200 Series

Tool 200i500LC

Aluminum wants to stick to your cutter, especially in the half-inch range where horsepower and heat both go up. Built-up edge turns what should be a clean cut into a tearing operation, and once it starts, the part finish is gone.

The 200i500LC addresses this with three-flute geometry that drops chip load per tooth while keeping production feed rates intact.
Lower chip loads mean less heat generation and reduced tendency for aluminum to weld to the cutting edge.
The TiB₂ coating adds hardness without the aluminum affinity problems you get with AlTiN.
Aluminum simply doesn't want to stick to titanium diboride the way it does to other coatings.
R0.008" corner radius strengthens the cutting edge without sacrificing sharpness.
High helix angle moves chips out before they can cause trouble.
