Tool 100m060A

Heavy roughing cuts in steel generate heat that kills tools fast. The 100m060A manages that thermal load through two complementary approaches: TiAlSiN coating and corner geometry designed for sustained contact.

TiAlSiN coating handles oxidation temperatures that exceed what TiAlN can manage, particularly in the 1800-2000°F range common in aggressive steel machining.
The aluminum content forms a protective oxide layer that actually strengthens as cutting temperatures rise.
Four flutes distribute chip load evenly, preventing any single cutting edge from carrying excessive thermal burden during side milling and roughing operations.
The R0.15" corner radius eliminates the sharp transition where fractures typically initiate under high feed rates.
That radius also spreads cutting forces over a larger contact area, reducing local stress concentrations that lead to premature edge failure in titanium and nickel alloys.
