Tork Craft Countersink Set 5Pce Set Carbon (8,12,16,19Mm C/W Hex Shank Adaptor)

The odd number of flutes reduces chatter on steel, brass and aluminium. Also used for plastic and wood application.

A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or
below the surface of the surrounding material. A countersink may also be used to remove the burr left from a
drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges.

Regardless of the name given to the cutter, the surface being generated may be a conical chamfer (plunging
applications) or a beveled corner for the intersection of two planes (traversing applications).

Application:

• DIY
• Construction
• Deburring, smoothing holes in steel, plastics and wood plate.

Features

• The chamfering effect of the countersink allows the head of the countersunk bolt or screw to sit flush with the
  material.
• Effectively removes burrs and sharp edges left after drilling or tapping.
• Gives the conical chamfer finish on plunging applications and a bevelled corner for the intersection of two
  planes in traversing applications.
