Cemented carbide countersinks are processing tools which drills pointed is cylindrical cone or plane, a countersink cut tapered countersink drill.

Cemented carbide countersinks plane, cylinders, cones, and other surface machining on the end face of the hole. The processed hole machining cylindrical countersunk holes, conical countersunk holes and the end face of the boss, use cemented carbide countersink drill.

Counterbore tools cemented carbide countersink drill, mainly the following:

(1) Cylindrical the countersink drill: mainly used for countersink cut cylindrical countersink. Cylindrical counterbore drill main cutting action is the end face of the blade, the bevel angle of the spiral grooves is the rake angle. Cemented carbide countersinks front guide post, guide post hole diameter of the workpiece already close clearance fit to ensure good centering guide. This guide column is detachable and can guide post and cemented carbide countersink drill made one.

(2) Cone the countersink drill: mainly used for countersink cut tapered counterbore. Different from the cone angle of the conical countersunk hole in a workpiece, the taper angle of the tapered counterbore drill (2φ) 60 °, 75 °, 90 ° and 120 °, wherein the most used is 90 °.

(3) End countersinks: end countersinks designed to countersink flatten port surface. The end face of counterbore drill can ensure the perpendicularity of the end surface of the hole with the bore centerline. When the machining diameter is small, in order to make the shank to maintain certain strength, can be a section of diameter of the toolholder head and the machining hole for the clearance fit to ensure a good guiding effect.

Cemented carbide countersinks standard tools, can be chosen according to the type of counterbore can also be changed with a twist drill ground countersink drill.
