1/4" Six-Flute ALL4 Square End Mill

This Canadian-made 1/4" carbide end mill features six flutes and a square cutting end for stable, productive machining with an excellent surface finish. Its ALL4 coating provides exceptional resistance to heat, abrasion and wear when machining high-temperature alloys and stainless steel.

More Cutting Edges for Productive Finishing

The six-flute geometry provides more cutting edges for efficient machining and smooth surface finishes in applications where chip evacuation is less demanding. Its stub-length construction improves rigidity, while the square end produces accurate shoulders and flat-bottomed cuts.
