100 Series

Tool 100i156LFA

Small diameter work means higher spindle speeds and more heat generation per unit of cutting edge. The 100i156LFA addresses this with TiAlSiN coating that maintains hardness at elevated temperatures while reducing friction between chip and tool face.

At 0.1563" diameter, four flutes provide the chip evacuation you need without compromising rigidity.
The R0.004" corner radius eliminates the stress concentration of a sharp corner while maintaining definition in profiling operations.
In steel and iron, that small radius extends tool life by distributing cutting forces over a slightly larger contact area.
TiAlSiN holds up well at the elevated surface speeds typical for this diameter in steel.
Less thermal variation means less edge degradation variation between parts.
The coating also reduces built-up edge formation in titanium and nickel alloys where chip adhesion becomes problematic.
