Thread Mill Inserts for Threading on CNC Milling Machines

THREAD MILL INSERTS
FOR THREADING ON CNC MILLING MACHINES
USING HELICAL INTERPOLATION PROGRAMS
ADVANTAGES OF MILL THREAD TOOLS

Same toolholder and insert can produce right and left-hand threads
A single insert & toolholder can produce a given thread on many diameters (external & internal)
Most inserts are double sided, having two cutting edges.
Thread is produced in one tool pass.
Mill Thread tools are capable of producing taper threads.
Improved productivity thanks to increased cutting speeds and multitooth type carbide inserts
Threading to one pitch of a shoulder in a blind hole.
Longer tool life thanks to special multilayer coating process
Lower tooling costs, considerably less expensive than using taps and dies
Since lower machine power required, smaller machine can produce larger threads in single operation with less idle time and tool changes.

Inserts are compatible with Kennametal, Stellram, Xactform & Iscar Holders!
GRADE MT7 - Sub micron TiAlN multi layer coated grade general purpose for all materials
