Crown Diamond Parting Tools - Cryogenic Steel Turning Tools

Parting tools cut parallel-sided grooves into your work piece. They are suitable for use in marking beads on the work piece, or separating a work piece from its waste mounted in the chuck to make removal easier once removed from the lathe.

Diamond parting tools are a relatively recent development. The diamond shape provides a reduced chance of the parting tool jamming when in use as the full edge is not in contact with the timber, allowing movement.

Blade length=165mm

Handle length =245mm

About Crown Cryogenic Steel

The Crown Cryogenic range are high quality turning tools with a difference. Using cryogenically treated tools means that now you can turn more and sharpen less often. The tools are made from M2 Steel that are heat treated normally then taken down to temperatures as low as -185&degC which changes the molecular structure of the steel.

The two main crystals in tooling steel are the larger and softer austenite and the smaller, more stable martensite. Normal heat treatment seeks to transform the austenite to martensite to produce steel with good wear characteristics and an amount of ductile properties.

The cryogenic process greatly enhances and accelerates the austenic transformation. Another benefit is that at these extreme temperatures, fine &lsquoeta&rsquo carbides are formed within the carbon structure. Growing very slowly and only at these very low temperatures, &lsquoeta&rsquo carbides are extremely small and act as a &lsquofiller&rsquo between the other crystals in the metal.

The combined effect of heat treatment and cryogenic processing is to produce a refined crystal structure in your hand tool that will give a lifetime&rsquos service by producing a blade that will retain its edge longer and give a superior &lsquofeel&rsquo in use.

All Crown Cryogenic Turning Tools are finished with beautiful black Ash handles.
