Tool 240i156C

Small diameter aluminum work amplifies every machining mistake. Heat buildup happens fast when there's nowhere for chips to go, and edge chipping becomes inevitable when interrupted cuts demand more from the geometry than it can deliver.

The 0.1563" diameter puts this tool in territory where thermal management and edge protection become critical.
Two flutes provide the chip clearance needed for high-speed aluminum removal while maintaining sufficient core strength for small-diameter work.
The R0.004" corner radius eliminates the sharp corner that would otherwise chip under interrupted cutting conditions common in aluminum fabrication.
TiB₂ coating adds a thermal barrier that keeps cutting temperatures controlled during the extended tool life cycles that small tooling demands.
The coating also reduces aluminum adhesion, preventing the buildup that leads to poor surface finish in soft materials.
