3 Flute Straight Shank Countersinks

Sherwood countersinks are a chatter-free cutter that produce an excellent burr-free finish it is capable of deburring and countersinking in one stroke with no "back-off" of tool.
Countersinking a hole leaves an angled conical, chamfered recess on the finished job, for a tapered head bolt or screw to seat correctly into this angled form. Countersink bits can be used for deburring holes as well.
It will also countersink aluminium with no secondary bulge.
Ideal for special applications and exotic materials, a choice of hard coatings is available.
