5/32" 4-Flute TiALN Single-End Square End Mill

This 5/32" diameter Skookum carbide end mill features a four-flute design, square cutting end and TiALN coating for precise milling in demanding shop environments. Its 5/16" length of cut and compact 2" overall length provide a rigid setup for controlled profiling, slotting and flat-bottom machining.

Stable Cutting with Heat-Resistant TiALN Protection

The four-flute geometry provides multiple cutting edges for smooth finishes, stable material removal and productive feed rates where chip clearance permits. Its square end creates flat-bottom features and defined corners, while the TiALN coating improves heat and wear resistance when machining materials such as steel, stainless steel and cast iron.
