Deburring cutters

Hand-held

If needed, the deburring cutter can be used by hand as the hexagon shank will fit into a 1/4″ (6.35mm) drive handle. This allows for the deburring cutter to be used in the same way as a hand-held deburring tool.

Mole grips are sometimes used to hold deburrers but this is not advised

Mole grips

Mole grips are a form of pliers – the jaws can be locked into position whilst the shank of the deburring cutter is gripped in the jaws.

Although this holding method is widely used, it is not recommended, as the shank of the deburring tool can sustain damage, which may affect the tool’s performance later on in its lifetime.
