200 Series

Tool 200i313S015C

Edge chipping on thin-walled aluminum parts usually traces back to impact loading at entry. Sharp corners hit the workpiece like a chisel instead of transitioning smoothly into the cut, especially on 5/16" tooling where deflection amplifies the problem.

The 200i313S015C carries a 0.015" corner radius that distributes cutting forces over a broader contact patch.
Impact loading drops, tool life extends, and part finishes improve because the edge isn't constantly work-hardening from shock.
Three flutes maintain reasonable chip load while the high helix geometry moves chips out before they weld to the flutes.
TiB₂ coating handles the demanding passes where uncoated carbide would wear too quickly.
The coating stays chemically neutral with aluminum.
No adhesion issues like you get with AlTiN.
