Description

The 60 degree angle on G137 countersinks will chamfer holes for special fasteners with 60 degree heads. The countersinks, even of large diameter, can be held in conventional holders and chucks, thanks to the reduced plain shank. With a bright finish to prevent workpiece material from sticking to the cutting edge of the tool, you can be sure of a clean and accurate finish. Manufactured from premium High Speed steel, G137 countersinks can be used to machine a wide variety of materials including steels, stainless steel and aluminium and their versatility is further enhanced as the tools can be used in machine applications where the countersink is held directly in the spindle.
