240 Series

Tool 240i313C

Small diameter aluminum work puts edge durability ahead of raw cutting speed. At 0.3125" cutting diameter, heat concentration becomes the primary concern as surface footage climbs with spindle RPM. The TiB₂ coating addresses this by reducing friction at the chip-tool interface while maintaining the sharp edge geometry needed for clean aluminum cutting.

The 240i313C balances chip evacuation with edge strength in confined spaces where conventional flood coolant may not reach effectively.
Two flutes clear chips without compromising the 0.3005" neck diameter required for deep pocket work.
The 0.004" corner radius eliminates the stress concentration of a sharp corner while preserving edge sharpness.
Designed for aluminum, copper, and plastics where surface finish and dimensional accuracy matter more than material removal rate.
The geometry works best on machining centers with adequate spindle speed capability.
