Duramill 56316 Double End HSS(Co) Milling Bit is a 3/4" diameter cobalt-high-speed-steel cutter with two usable ends. The tool measures 5-1/2" in overall length and carries the part number 56316. Built from HSS(Co), it provides wear resistance for metalworking milling tasks, and the double-end design lets you rotate to a fresh cutting edge when one end wears, effectively extending tool life.
