KENNA PERFECT Inserts – Heat-Resistant Alloys & Titanium 

Tool Tips: 

Grade KC5510 

Grade KC5510 is your first choice for finishing to medium machining in heat-resistant materials and 

titanium. The PVD coating has been specially formulated to address the high heat generated when 

machining these materials. Processing speeds can be doubled over conventional TiAlN coated 

products. The fine-grain tungsten carbide substrate offers excellent strength and deformation 

resistance and is ideal for the positive sharp geometries utilized in machining these materials. 

Grade KC5525 

Grade KC5525 utilizes the same high-temperature PVD coating as grade KC5510 combined 

with a higher cobalt, fine-grain tungsten carbide substrate to add additional strength to the cutting 

edge. Grade KC5525 is your first choice for interrupted cuts. 

GG-FS 

The ground high positive -FS geometry is ideal for finishing cuts where size control, finish and 

minimization of part deflection are considerations. In combination with grade KC5510 finishing 

cuts at 250 to 350 sfm are possible greatly reducing processing time. 

MG-MS 

The precision molded -MS geometry utilizes a micro-finished edge preparation to increase edge 

toughness for medium machining applications where sharp edges are not required. In combination 

with advanced grades KC5510 and KC5525, metal removal rates can be greatly increased while 

maintaining process security. 

Grade KY1540 

Replace whisker ceramics with KY1540 and pay less for the same or better performance. The 

toughness of KY1540 enables it to be used at high ceramic speeds where only whisker ceramics 

have been run in the past, and at higher feed rates. KY1540 can also effectively run at speeds lower 

than whisker ceramics (< 500 sfm) when speed is constrained by machine capability or fixturing. 

14

KENNA PERFECT Inserts – Heat-Resistant Alloys & Titanium 

Tool Tips: 

Grade KY2100 

Kyon 2100 is compositionally designed to minimize chemical interaction with the workpiece material. 

KY2100 excels at high-speed milling and finish turning of high-temperature alloys. 

Ceramic Inserts, Geometry 

The strength and property retention of high-temperature alloys make it important to choose ceramic 

insert shapes that maximize edge strength. When possible, use round ceramic inserts for the 

best results. 

Ceramic Inserts, Edge Preparation 

For turning of high-temperature alloys, the general recommendation is to use a T-land width or hone 

size that is smaller than the feed rate. The exceptions to this rule are milling, turning with heavy 

interruptions, or turning hardened materials (>50 HRC). In those instances, it is recommended to use 

a T-land width greater than the feed rate. 

Pre-chamfering 

Pre-chamfering parts in the initial and intermediate stages of machining can greatly increase tool life 

by reducing the shock that occurs when entering the cut and breaking through scale. 

High-Pressure Coolant 

When machining heat resistant alloys, high-pressure coolant can be used to reduce the high heat 

generated at the cutting zone. This allows for higher cutting speeds with similar tool life. Typically, 

speeds can be doubled with properly applied high-pressure coolant. 

15

New Cutting Tool Technologies 

Grades KC5510 and KC5525 

Kennametal’s newly developed advanced PVD 

TiAIN coated carbide grades KC5510 and KC5525, 

in high positive rake geometries GG-FS and 

MG-MS, have overcome many of the problems 

associated with machining heat-resistant alloys 

and titanium materials. These new products are 

revolutionizing productivity in finishing and medium 

machining of super alloys. Cutting speeds as high 

as 400 sfm can be attained with finishing grade 

KC5510. Typically, speeds can be doubled over 

a conventional PVD product with no impact on 

tool life (see figures 1 and 2). 

CNGG-432FS KC5510 

Tool life: 26.5 minutes

Tool life: 7.5 minutes

Grade KC5510 is an advanced PVD coated 

fine-grained tungsten carbide grade specifically 

engineered for the productive yet demanding 

machining of high-temperature alloys. The finegrain 

tungsten carbide (6% cobalt) substrate has 

excellent toughness and deformation resistance. 

The advanced PVD coating allows for metal 

cutting speeds double those of conventional PVD 

coated materials. 

Grade KC5525 utilizes the same advanced PVD 

coating as grade KC5510 combined with a finegrain 

tungsten carbide (10% cobalt) substrate. 

The higher cobalt content provides added security 

in interrupted cuts while the fine grain tungsten 

maintains deformation resistance. 

In conjunction with grades KC5510 and KC5525, 

Kennametal has engineered two new chip control 

geometries specifically designed for machining of 

superalloys. The GG-FS geometry is precision 

ground for optimal performance in finish cuts where 

low forces are required and dimensional control is 

critical. The MG-MS geometry is designed for medium 

to heavy cuts and is precision molded for 

added economy. Both geometries are high positive.

In developing these products, Kennametal 

conducted extensive metal cutting tests internally 

and in conjunction with our customers. In over 

100 tests, these new high-performance products 

outperformed the competition 95% of the time. 

Figures 3-11 (pages 19-21) document tool life in 

minutes, helical cutting length in feet, and volume 

of metal removed in in 3 for grade KC5510 

CNGG-432FS and CNMG-432MS. Materials 

machined were ~6 inch diameter bars of Inconel 

718 (39 HRC) and Ti-6Al-4V (30 HRC). Feed rates 

and depth of cuts employed in these internal tests 

are indicated in the test results. End-of-tool-life 

criteria used are .012 flank-wear, nose wear, or 

depth of cut, and .004 crater depth. Use this 

metalcutting data as a benchmark for planning your 

machining operations to realize optimum economy. 

Calculate the helical cutting length based on the 

feed rate, workpiece diameter and length of cuts. 

Determine the optimum cutting speed from data in 

the following charts. 

Note that when machining Inconel 718, grade 

KC5510 in CNGG432-FS geometry delivers tool life 

as high as ~50 min at 200 sfm, .005 ipr, and .005 

doc (fig. 3). This insert can be run even at 400 sfm, 

with good tool life. For carbide tools, these speeds 

represent a 100% plus improvement in productivity 

over conventional PVD coated tools. Under the 

conditions employed, the maxiumum amount of 

metal removed is over 6 in 3 .

High-Temperature Materials 

Metallurgy 

High-temperature materials are alloys that are 

generally used above ~1000°F (540°C) because of 

their ability to retain strength at high temperatures. 

These materials are also referred to as 

“superalloys”. They are usually classified into three 

groups: iron-nickel-, nickel-, and cobalt-base alloys. 

The properties are developed by a combination of 

cast or wrought processing (e.g. forging) followed 

by heat treatment. Chemical composition and 

processing steps are keys to obtaining optimum 

properties. The processing may include solution 

annealing or solution annealing followed by aging 

or precipitation hardening treatment. The purpose 

of solution annealing is either to homogenize an 

alloy or dissolve all second phases in the matrix to 

produce maximum corrosion resistance or to 

prepare an alloy for subsequent aging treatment. 

The precipitation (aging) treatment involves heating 

the solution-annealed alloy to a predetermined 

temperature and holding it at that temperature until 

precipitation of one or more phases occurs. 

Superalloys are extensively used in aircraft engines 

and industrial gas turbines for power generation. 

They also find application in petrochemical, oil, and 

biomedical industries due to their excellent 

corrosion resistance. 

Titanium alloys are also included in this category in 

view of their high temperature strength, high 

strength/weight ratio, and corrosion resistance. 

They are used in the aerospace, medical, and 

chemical industries. 

Iron-Nickel-Base Alloys 

Iron-nickel-base alloys are the weakest of the 

superalloys at elevated temperatures. They owe 

their high temperature strength to solid solution 

hardening (hardening produced by solute atoms 

dissolved in the alloy matrix) or precipitation 

hardening (hardening produced by precipitate 

particles). The most common precipitates are 

gamma prime, γ’, Ni 3 (Al,Ti) [e.g. A-286], and 

gamma double prime, γ” (Ni 3 Nb) [Incoloy 909]. 

Alloys such as 19-9DL and Haynes 556 are solid 

solution hardened with molybdenum, tungsten, 

titanium and niobium. 

Iron-nickel-base alloys are primarily used in the 

wrought condition for gas turbine disks and blades. 

Most wrought alloys contain high levels of 

chromium to provide corrosion resistance. 

Nickel-Base Alloys: 

Like iron-nickel-base materials, the nickel-base 

alloys are either solid solution strengthened or 

hardened by intermetallic compound precipitation in 

a face centered cubic (fcc) matrix. Alloys like Inconel 

625 and Hastelloy X are solid solution strengthened. 

The solid solution hardened alloys may get 

additional strengthening from carbide precipitation. 

Alloys such as Inconel 718 are precipitation 

hardened. A third class of nickel-base superalloys, 

typified by MA-754, is strengthened by dispersion of 

inert particles such as yttria (Y2O3) coupled in some 

cases with γ’ precipitation (MA-6000E). 

Cast nickel-base alloy (Inconel 718). Nickel-base alloy, Hastelloy B, 

solution annealed. 

Nickel-base alloy, Udimet 720, 

as forged. 

28


Nickel-base alloys are available in both the cast 

and wrought forms. Highly alloyed compositions 

such as -Rene 95, Udimet 720, and IN100 are 

produced by powder metallurgy followed by forging. 

For the above wrought alloys and for cast alloys 

(e.g. Rene 80 and Mar-M-247), the strengthening 

precipitate is γ’. For Inconel 718, the strengthening 

precipitate is primarily γ”. 

Alloys such as Inconel 725 containing niobium, 

titanium, and aluminum are strengthened by both γ’ 

and γ” precipitates. 

Cobalt-Base Alloys 

Cobalt-base alloys are generally stronger and 

possess superior corrosion resistance at 

temperatures above 2000° F (1093° C). They are 

strengthened by a combination of solid solution 

hardeners (iron, chromium, and tungsten) and 

carbides (titanium, tantalum, hafnium, and niobium). 

These alloys are available in cast or wrought form. 

The cast alloys such as Stellite 31 are used in the 

hot sections of gas turbines (as air-foils, i.e. blades 

and vanes). A typical wrought alloy is Haynes 25. 

The wrought alloys are produced principally as 

sheet and are used in combustor parts. 

Titanium Alloys 

Pure titanium (Ti) undergoes a crystallographic 

transformation from hexagonal close packed, hcp 

(alpha, α) to body centered cubic, bcc (beta, β) 

structure as its temperature is raised through 882° 

C. Alloying elements such as tin (Sn) when 

dissolved in titanium do not change the 

transformation temperature, but elements such as 

aluminum (Al) and oxygen (O) cause it to increase. 

Such elements are called “α stabilizers”. Elements 

that decrease the phase-transformation 

temperature are called “β stabilizers”. They are 

generally transition metals. Commercial titanium 

alloys are thus classified as “α”, “α-β”, and “β”.The 

α-β alloys may also include “near α” and “near β” 

alloys depending on their composition. 

Alpha (α) Alloys 

Pure titanium and titanium alloyed with α stabilizers 

such as tin and aluminum (e.g. Ti-5Al-2.5Sn) are 

classified as α alloys. They are non-heat treatable 

and are generally weldable. They have low to 

medium tensile strength, good notch toughness, 

and possess excellent mechanical properties at 

cryogenic temperatures.

29


Beta (β) Alloys 

Beta (β) alloys contain transition metals such as V, 

Nb, Ta, and Mo that stabilize the β phase. 

Examples of commercial β alloys include 

Ti-11.5Mo-6Zr-4.5Sn and Ti-15V-3Cr-3Al-3Sn. 

Beta alloys are readily heat treatable, generally 

weldable, and have high strengths. Excellent 

formability can be expected in the solution treated 

condition. However, β alloys are prone to ductilebrittle 

transition and thus are unsuitable for 

cryogenic applications. Beta alloys have a good 

combination of properties for sheet, heavy sections, 

fasteners, and spring applications.

and a fine alpha-beta matrix structure. 

Near α alloy Ti-6%Al-2%Sn-4%Zr-2%Mo showing alpha grains 

and a fine alpha-beta matrix structure. 

Beta alloy Ti-3%Al-8%V-6%Cr-4%Mo-4%Zr. 

Alpha-Beta Alloys 

These alloys feature both α and β phases and 

contain both α and β stabilizers. The simplest and 

most popular alloy in this group is Ti-6Al-4V, which 

is primarily used in the aerospace industry. Alloys 

in this category are easily formable and exhibit high 

room temperature strength and moderate hightemperature 

strength. The properties of these 

alloys can be altered through heat treatment.

Machinability of Superalloys 

High-Temperature Alloys 

Generally, the high-temperature alloys have poor 

machinability. The very characteristics that provide 

high temperature strength in these materials are 

responsible for their poor machining behavior. 

Among the super alloys, iron-nickel-base alloys are 

easier to machine than the nickel-base and cobaltbase 

alloys under similar conditions of heat 

treatment. For aerospace applications, the surface 

condition of the machined workpiece is of concern 

because of the role it plays in the useful life of the 

component under cyclic loading. Great care is 

taken to ensure that there is no metallurgical 

damage to the component surface after the final 

finishing pass. 

The accompanying table compares the physical 

and mechanical properties of nickel-base and 

titanium alloys with those of AISI 4340 alloy steel. 

The nickel-base alloys have high tensile strength 

at high temperatures (650° C), lower thermal 

conductivity, and similar density and Young’s 

Modulus (measure of stiffness) as alloy steels. 

The titanium alloys have even lower thermal 

conductivity, lower stiffness, and lower density than 

the nickel-base alloys. These characteristics affect 

their machining behavior as indicated below.

Expert Application Advisor 

Factors Affecting the Machinability of Superalloys 

• Their high strength at cutting temperatures 

causes high cutting forces and generates more 

heat at the tool tip (compared to alloy steels). 

• Because of their poor thermal conductivity, heat 

produced during machining is transferred to the 

tool and increases the tool tip temperatures. 

High tool tip temperatures contribute to 

oxidation and diffusion of the tool material into 

the chip leading to cratering and excessive flank 

wear. 

• The presence of hard, abrasive intermetallic 

compounds and carbides in the microstructure 

causes severe abrasive wear on the tool tip. 

• The high capacity for work-hardening in 

these materials causes depth-of-cut notching 

on the tool. 

• The chip produced during machining is tough 

and continuous, which requires good chip 

control tool geometry. 

Speed is the single most important factor that 

determines tool life. Feed rate and depth of cut are 

also important factors. A copious amount of coolant 

is required with carbide tools to reduce temperature 

build-up and tool wear.

Machinability of Titanium Alloys 

Machining of titanium alloys is as demanding as 

cutting of other high temperature materials. 

Titanium components are machined in the forged 

condition and often require removal of up to 80% 

of the weight of the workpiece. 

The high chemical reactivity of titanium alloys 

causes the chip to weld to the tool leading to 

cratering and premature tool failure. The low 

thermal conductivity of these materials does not 

allow the heat generated during machining to 

dissipate from the tool edge. This causes high tool 

tip temperatures and excessive tool deformation 

and tool wear. 

Titanium alloys also retain strength at high 

temperatures and generate high heat and cutting 

forces. In addition, heat and cutting force are 

concentrated in a small chip contact area on the 

rake face of the tool. The low elastic modulus of 

these materials causes greater workpiece 

deflection that results in tool vibration, tool chatter, 

and poor surface finish. In addition, the high 

work hardening tendency of titanium alloys 

causes high cutting forces that may lead to depthof-cut 

notching. 

Alpha (α) titanium alloys have low tensile strengths 

and produce low cutting forces. In contrast, 

significantly higher cutting forces are generated 

during machining of α-β and β alloys. 

A generous quantity of coolant with appropriate 

chemistry, should be used to minimize tool tip 

temperatures and rapid tool wear. Positive rake 

sharp tools will reduce cutting forces and 

temperatures and minimize part deflection.

Nose Radius Selection and Surface Finish 

for Conventional Inserts 

1 

2 

3 

4 

Nose radius and feed rate have the greatest impact 

on surface finish. To determine the nose radius 

required for a theoretical surface finish, use the 

following procedure and the chart above. 

1 Locate the required surface finish (rms or AA) 

on the vertical axis. 

2 Follow the horizontal line corresponding to the 

desired theoretical finish to where it 

intersects the diagonal line corresponding 

to the intended feed rate. 

3 Project a line downward to the nose radius 

scale and read the required nose radius. 

4 If this line falls between two values, choose 

the larger value. 

• If no available nose radius will produce the 

required finish, feed rate must be reduced. 

• Reverse the procedure to obtain surface 

finish from a given nose radius. 

NOTE: Peaks produced with a small radii insert (top) compared 

to those produced with a large radius insert (bottom).

53

Insert Edge Preparation 

Edge Preparation for Kennametal’s Advanced Cutting Tool Materials 

Edge preparation is the term for the intentional 

modification of the cutting edge of an indexable 

insert to enhance its performance in a 

metalcutting operation. 

Ceramic cutting tool materials have a much 

higher hardness, but lower toughness, compared 

to conventional carbide materials. Because of this, 

ceramic materials have good bulk strength but 

lower edge strength versus carbide. 

To optimize performance of ceramic cutting tools, 

it is critical that tool material, workpiece material, 

and machining conditions be considered during 

edge preparation. To achieve optimum edge 

preparation, make the minimum amount of 

modification necessary to distribute forces 

sufficiently enough to prevent chipping and 

catastrophic insert failure. Edge preparations for 

standard inserts made with specific ceramic grades 

are determined by target applications and listed in 

the KENNA PERFECT insert selection system. 

There are three choices of edge preparation for 

ceramic materials: 

There is a tradeoff to the benefits of edge 

preparation. Increasing the width “T” of the T-land or 

the angle “A” increases the overall cutting forces 

acting on the inserts. This can negatively affect 

the wear rate of the insert and/or deformation of a 

thin-walled workpiece. 

For most high-temperature alloy turning applications, 

use a T-land width smaller than the feed rate. For 

heavily interrupted turning, hard turning (workpiece 

>50 Rc), and milling applications, use a T-land 

width larger than the feed rate 

2. Hone 

Hones protect the insert cutting edge by 

eliminating the sharp edge and distributing the 

cutting forces over a larger area. Hones generally 

are recommended for continuous or finishing 

operations; however, depending on the workpiece 

material, they can be used for interrupted or 

heavy cutting. 

1. T-land 

2. hone 

3. T-land plus hone 

1. T-land 

T lands protect the insert cutting edge by directing 

forces into the greater part of the insert, rather 

than to the smaller cross section of the sharp 

edge, during the metalcutting process. This helps 

prevent chipping and catastrophic failure. 

3. T-land plus hone 

In aggressive applications, such as interrupted 

turning, chipping can occur at the intersection of 

the T-land and flank surface of the ceramic insert. 

Eliminate this condition by applying a small hone 

at the intersections while leaving the other attributes 

of the T-land unchanged.
