Working geometry
The drilling section makes the hole and the countersink forms an angled recess at its opening.


Designed to drill and countersink holes.
The solid-carbide cutting section provides rigidity and wear resistance at the working edge.
This Mastercut 90° drill and countersink is designed to drill and countersink holes.
The drilling section makes the hole and the countersink forms an angled recess at its opening. Check the pilot and countersink dimensions separately when selecting the tool. The solid-carbide cutting section provides rigidity and wear resistance at the working edge.
The 1/8 in cutting diameter and 1/8 in cutting length define the working section of this version. Its 5/16 in shank fits a holder or collet matched to that diameter.
