Where ADKT inserts are used

The 85° parallelogram is the common shape for 90° shoulder milling cutters, which are also used for face and slot milling.

ADKT is a positive (15° clearance) 85° parallelogram milling insert. It has a countersunk hole for a clamping screw. The chipbreaker is on one face only. The positive geometry keeps the cutting forces down.

Use the insert format, size and corner configuration specified by the cutter manufacturer; check the pocket and clamping system before ordering.
