Niagara Cutter 17010459 Cobalt Steel Square Nose End Mill - 2.000" Cutting Diameter, 8 Flutes, 30° Helix, Weldon Shank - Uncoated Roughing End Mill for Metalworking, Milling, and CNC Machining - Perfect for Industrial Manufacturing and Precision Engineering Applications

Multi Flute / M42 8 percentage Cobalt Steel.

Roughing end mills have chip-breaking cutting edges that remove material in less time than conventional end mills

Fine-pitch tooth design is suitable for machining high-temperature alloys

Square end creates sharp, unrounded cuts and has a corner chamfer to strengthen the cutting edges

Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel

Number of flutes varies by diameter for optimum feed and cut rate
