100C Series

Tool 100Ci156LA

Small diameter work in tough alloys tests your setup and your tooling. The 100Ci156LA handles 0.1563" cuts in steel, iron, titanium, and nickel alloys without the chatter or premature wear that derails tight-tolerance jobs.

Four flutes keep cutting forces balanced while chipbreaker geometry fractures chips before they can pack the flutes or pull heat back toward the spindle.
This matters when you're holding tenths on small features where heat buildup kills surface finish and dimensional stability.
TiAlSiN coating adds thermal barrier protection at higher cutting speeds without building up on the edge like some coatings do in sticky materials.
The R0.004" corner radius strengthens the cutting edge against microfracture while maintaining sharp entry characteristics.
