Improved Coolant Thru
Two coolant holes for effective chip
removal and cooling of cutting edge
New Slanted Insert Design
Provides exact insert location for
high repeatability
Simple Clamping System
Simple and fool-proof, the new clamping
system uses one large screw to secure the
insert in the holder
Applications

Calculation of N [RPM]
N = 1000 x V c
π x D
Vc = N x π x D
1000 Vc
N - Revolution Per Minute [RPM]
V c - Cutting Speed [ft/min]
D - Workpiece Diameter [inch]
