Where WCMT inserts are used
Inserts of this format are used in indexable drills. The drill maker states which insert goes in the centre pocket and which in the peripheral pocket; some drills take the same insert in both.
WCMT is a positive (7° clearance) 80° trigon drilling insert. It has a countersunk hole for a clamping screw. The chipbreaker is on one face only.
Send us the drill model and we confirm the insert.
