Thru Coolant 

Turning, Boring 

and Threading 

Tools 

Dorian Tool’s Jet-Stream Thru Coolant Cutting Tools use a 

patented thru-coolant locking clamp which is precisely aimed to 

direct high pressure, high velocity coolant exactly onto the cutting 

edge of the carbide insert, from a short distance of ¼”. 

This controlled Jet-Stream coolant, directed onto the insert chip 

interface (right under the chip and over the insert cutting edge) will 

dissipate the generated heat very effectively as well as lubricate 

the cutting edge of the insert, causing the chips to hydroplane 

over the insert surface instead of adhering to it. As a result, the 

insert will operate at a constant low temperature, with a clean 

and undamaged cutting edge, changing the way metal is cut. 

Higher speeds and feeds can be achieved, with a better 

surface finish, tolerance control and machining performance. 

The insert life is extended up to 200%.

Performance is Improved With: 

• Extreme Lubrication at the cutting edge 

• Extreme Heat Dissipation at the cutting edge 

• Constant Low Cutting Edge Temperature 

• Greater Chip Control and Evacuation 

• Chip Breaking at High Pressures 

• Smooth Cutting Action and Surface Finish 

• Increased Speeds and Feeds 

Why The Dorian Jet-Stream 

The advanced and unique technology of the Jet-Stream Thru 

Coolant System, offers the ability to process the coolant supplied 

from the machine’s pump with maximum efficiency, speed 

and volume. The speed and volume of the coolant coming out 

of the Jet-Stream nozzle directly onto the insert cutting edge 

will improve machining performance. 

Anyone who is even casually involved with metalworking 

knows that cutting tools generate large amounts of heat, which 

is detrimental to the usable life of carbide inserts. 

To overcome this problem with standard turning tools, the operator 

aims the coolant by hand at the tool using snap together 

plastic beads or copper tubing. Every operator does it differently, 

and during machining operation the coolant lines are 

frequently pushed out of alignment so that the operator has 

to manually readjust the aim of the coolant, often every time 

they change a part. One coolant manufacturer estimates that 

40% of the time the coolant doesn’t hit the tool or the part. 

Even when the coolant hits the tool there is no directional control; 

it typically comes from the top and hits the chips before it 

can reach the insert’s cutting edge where heat is accumulating. 

Real process control from setup to setup and throughout a production 

run is virtually nonexistent. 

Improved Productivity: 

The Jet-Stream Thru Coolant System will immediately improve 

machine performance with higher sfm (surface footage), 

extended tool life, ability to hold closer tolerances, and 

improvement of surface finish. The Jet-Stream tooling will 

excel because it makes machining simple and easy for materials 

ranging from low carbon steel to high temper alloys, exotics 

and aerospace materials. 

How to Optimize Productivity: 

A minimum of 70 psi is required for the Jet-Stream to show 

improvements in machining performance. To reach optimum 

results, higher coolant pressure and volume are necessary. 

Maximum performance will be achieved at 1000 psi with a coolant 

volume of ½ gpm (gallon per minute) per machine horsepower. 

Example: A 15 HP machine will need a coolant pump of 

1000 psi with 7.5 gpm of coolant volume. 

How To Guarantee Results: 

• DO NOT exceed the insert machining data. 

• DO Not take too deep of a cut without the proper 

coolant pressure and volume. 

• If the chips are not breaking your machining data 

or insert are incorrect. 

• Make sure you have a large enough coolant pump on 

the machine to supply sufficient coolant volume when 

high and super high pressure is required.

Internal 

The most popular threading and grooving system in 

the industry. The toolholders and boring bars are to 

be used with threading or grooving inserts, for either 

external or internal applications, in right or left hand 

cutting direction. 

• Two (2) types of locking systems available: 

• "M" - Multi lock system for TNMA style insert 

• "S" - Torx screw locking system for TNMC style 

insert 

On edge 60° triangle threading inserts have three (3) 

cutting edges. The insert is mounted on the side or end 

of the threading holder or boring bar. The same insert 

can be used for either OD or ID threading, in right hand 

or left hand cutting direction. 

• "A" style with straight hole for "M" style holder and 

boring bar 

• "C" style with double countersink for "S" style holder 

and boring bar 

The on edge system offers a complete selection of 

thread, API, and groove form inserts. 

The most compact system designed for external or 

internal threading applications, for right and left hand 

cutting direction. The great advantage of this system over 

others, is the ability to thread the smallest bore diameters 

allowed in single point threading operation. 

The three (3) cutting edge insert is locked down in horizontal 

position over the holder or boring bar, allowing 

the chip to flow without restriction. 

The laydown threading system offers the most complete 

selection of thread-form insert line in inches (TPI), metric 

(ISO), and API with single and multi thread form, in full 

or partial thread profile. 

The unique clamping design of DorNotch, makes it the 

most rigid threading system. The insert nested on the 

side of the holder or the end of the boring bar is held 

extremely secure with a top clamp, forcing the insert 

down and against the walls of the pocket. This assures 

the best tool life, a chatter free surface finish, and a 

precise workpiece quality. 

DorNotch threading and grooving holders and boring 

bars are built with precise quality. They are available in 

many sizes, making the DorNotch holders and boring 

bars the perfect choice for heavy duty threading applications, 

for either OD or ID applications, in right hand or 

left hand cutting direction. 

The DorNotch threading and grooving system offers 

a large selection of thread, API, and groove form 

inserts.

• As a rule of thumb, divide the total number 

of infeed passes required for a single tooth 

insert by the number of teeth on a multi-tooth 

insert to find total infeed passes needed. 

• Find accumulated infeed depths for multiples 

of the tooth number 

(For 3 teeth find a p 

for passes 1, 3, 6, 9, etc)

Dwell tool in bottom of cut no more than three revolutions. 

Back Turning 

Insert center height should be kept at the center line of the 

workpiece to .005 above the centerline 


Maximum depth of cut should be kept below .110 for .250 IC 

inserts and .150 for .375 IC inserts 

Wide Grooves 

Plunge both sides of the groove width first. 

Plunge the center area to clean out the remaining material. 

If angled walls are required for the groove, perform as a final 

operation. 


See profiling to finish the groove. 

Profiling 

Rough the profile as if cutting a wide groove. 

Plunge from each end and turn to the center of the profile in 

order to ensure wall perpendicularity 

If using a radius insert, depth of cut should not exceed the 

insert radius size.

Full Profile vs Partial Profile for Laydown Threading 

Full Profile Partial Profile 

• Threads remain concentric since both the major and minor 

diameters are machined at the same time 

• Final pass machines the thread crest- No Deburring! 

• Thread dimensions match industry standard 

• Fewer passed required- saves time and improves productivity 

• Stronger insert for longer tool life 

• A variety of pitches may be created by a single insert 

• Provides for creating thread forms that are not 

industry standard 

• Requires a separate finishing pass to machine the thread 

crest and deburr the thread 

Single Tooth vs Multi-Tooth for Laydown Threading 

Single Tooth

Insert 

Infeed 1 

Single Tooth

Pros Cons Pros Cons 

• Available in either full or partial 

inserts for greater variety of 

thread pitch option 

• Good chip control 

• A large number of passes is 

required to machine a full depth 

thread 

• Multiple teeth require a smaller 

number of passes to create a full 

depth thread 

• Increased tool life 

• Better productivity 

• Large clearance is needed to 

accommodate the full row of teeth 

• Extremely high cutting forces 

result from the large insert 

engagement length 

Special Considerations for Laydown Threading 

Thread Compatability 

Internal and external threads can have different 

variables, such as depth and radii. This can lead to 

the incompatability of the threads. 

Distance 

between tooth 

Thread Cutting Rake 

The rake for Dorian's threading external toolholders 

is 10° and the rake for Dorian's internal threading 

bars is as follows: 

Insert Size 11, 16, 22 - 15° Insert Size 27 - 10° 

This difference in the rake angle for the internal and 

external threading tools allow for the radial clearance. 

Insert Configuration 

Inserts and threading tools should always match. The 

insert for an internal right hand boring bar must be an 

internal right hand insert. 



Standard Thread Helix Angles 

Simplified Formula 

λ 

P = Pitch 

D = Major Dia. 

TPI = Threads Per Inch 

λ = Helix Angle 

λ = arctan 

λ = 20/PD 

Example: 

D = 1.18 

P = 16 TPI 

λ = 

P 

π x D 

20 

16 x 1.18 

P = 1.0 

TPI 

= 1º 

Standard and Slanted Shim Seats for Laydown Threading 

Toolholders pockets have a built in 1.5º helix angle. This angle may be adjusted to better match the thread helix angle by simply changing the Shim Seat. 

Negative helix is usually used when threading RH thread with LH holder or LH thread with RH holder.

• Minimum threading dia. .950" 





Miniature Threading Bars Take Over Where Taps Leave Off 

• Small Hole Capacity - to a minimum of .226 / 6mm. 

• Greater productivity through better tool utilization - 

For CNC turning centers and manual lathes and a wide range of workpiece 

materials. Also, creates less machine load than taps. 

• Better finish - Miniature threading bars result in thread 

geometry and closer tolerances. 

• Fully threads a blind hole - Threads deeper 

than a tap and never gets stuck. 

TYPICAL CNC APPLICATION 

• One Set-up 

• Two Threads 

Two threads, NPT 1/8"-27, in one operation on a CNC 

lathe with bar feeder. The whole part is produced in 

one set-up, therefore, increasing productivity. 

The Miniature and 

Ultra MiniatureThreading bars are replacing 

taps with many advantages. The small inserts and the low 

speed coated grades available make threading to a minimum 

diameter of .236 in or 6 mm possible. 

06IR-A60-DVP656- All these taps, 

and more, can be replaced cost effectively with 

only this one insert.

six models for any milling, drilling, tapping and face 

milling operations. The Universal CNC Adjustable 

Angle Heads have two positioning axes and are offered 

in ER25 and ER32 collet toolholding systems.

expensive 4th & 5th axis rotary tables. The 90º CNC 

Adjustable Angle Heads have one positioning axis 

and are offered in ER16, ER25 and ER32 collet 

toolholding systems as well as CAT/ISO/BT 40 taper 

toolholding system. 

Dorian Tool offers a wide range of knurling tools to 

cover most knurling applications. Since the introduction 

of Dorian’s modular knurling tool system, knurling has 

never been easier. The knurl tools range from cutting to 

forming a knurling pattern. The cutting style knurl tools 

have revolutionized knurling. It is faster and requires 

less pressure to create a knurl over forming. A wide 

range of knurl wheel pitches are also available.
