Description

CARP parting tool diamond point 19 mm

A 19 mm high CARP parting tool diamond point. The shape of this tool reduces frictional heat. This is good for the chisel and for the wood. A parting tool is mainly used for inserting dimensions in the workpiece. When sharpening the chisel, make sure the sharpness stays exactly on the thickest part of the chisel. At the thickest point the chisel is 4 mm wide.

Handle
A handle for a woodturning tool is sometimes long and sometimes short. Depending on the function of the tool. A bowl gouge or roughing gouge needs a long handle, a spindlegouge needs to be manoeuvrable and so a short handle is useful. Furthermore, it is useful to easily recognise the handles when they are hanging in the rack.

CARP tools

Carp tools are made of hardened HSS M2 steel. They are forged and/or milled, then hardened to 63-64 HRC, then ground and polished.

Harden

How good a chisel is depends largely on the hardness and toughness of the steel. So a lot of attention is given to hardening chisels. This is a lengthy process. It starts with heating the steel. This is done in absolute vacuum. Then the chisels are hardened in 3 steps, before undergoing another process of heating and cooling. Here, temperatures of up to -185 degrees are reached (in liquid nitrogen). Quality is strictly monitored. Between 5 and 10% of each batch of chisels is tested for hardness and toughness.
