Anti-vibration through hole, tip, hexagonal shank, cutting edge

Hexagonal shank

Hexagon shank of a de-burring cutter has six sides for added grip The hexagonal shank provides a surface for the machine chuck (or drive handle) to grip the cutter securely.

The shank has 6 flat sides which makes it easier to be gripped/held. Hexagonal shanks are usually measured across their flats.

The shank is a nominal size of  1/4” drive, this means it will fit in most three jaw drill chucks.


Tip of a de-burring cutting cutter allows for centring The tip of the cutter helps the tool to find the centre of the machined hole to give an equal and accurate chamfered edge.

Cutting edge

Cutting edge of a deburring cutter is only on one edge of the elliptical hole The cutting edge removes any burrs and leaves the edge of the machined hole with a chamfer.

     When a tool has only one sharp edge for removing material,  this edge is called the cutting edge. If the tool as multiple cutting edges in a spiral, these are called flutes.

Elliptical hole

Elliptical hole/anti vibration through hole, has only one cutting edge, and is designed to remove material as it cuts. The elliptical or anti-vibration through hole removes freshly cut material away from the cutting edge, preventing the tool becoming clogged.

The position of the hole in relation to the head of the tool means that it cuts cleanly and without chatter.

An elliptical hole is an egg shaped hole,  or tilted/out of round hole.
