200 Series

Tool 200i500Y040C

Aluminum loves to weld itself to cutting edges, especially when you need clean walls on deeper pockets. Push the feeds to clear chips fast enough and suddenly you're work hardening. Back off and heat builds up anyway.

The 200i500Y040C handles this through controlled chip thinning.
Three flutes distribute cutting load while the high helix angle moves chips out before they can reheat and stick.
TiB₂ coating adds thermal barrier properties without the aluminum affinity that makes AlTiN coatings counterproductive.
The coating lets you hold feeds in interrupted cuts where uncoated tools would load up.
Corner radius measures R0.04".
That small radius strengthens the cutting edge enough to handle demanding passes while keeping corner definition tight for precision work.
Built for aluminum, copper, and plastics where built-up edge kills surface finish.
