Insert, APMT1135PDER-M Carbide, Tormach

This is my third time ordering these carbide inserts for running plastic parts on my Tormach, and the high polish face really cuts down on built-up residue. They hold an edge noticeably longer than the budget ones I tried before.

The polished face on these inserts makes a huge difference in chip flow on aluminum—finish came out almost mirror-clean. They’ve held up through a solid batch of plastic parts without any edge wear I can notice.

I’ve been running these through some 6061 aluminum parts and the polished face makes chip evacuation noticeably smoother, leaving a cleaner finish than my usual inserts. They hold an edge well on plastic too, so I’ve stopped switching tools between materials.
