They are widely used for forming tenons with a peeling cut and rolling beads on a spindle. This name comes from the motion of the tool while shaping a bead. You can use the tool to cut a pair of convex surfaces back to back, which constitutes a bead if the spacing, curvature, and so forth are correct.  \u003c\/p\u003e\n\n\u003cp\u003eBlade length = 185mm\u003cbr\u003e\nHandle length = 254mm\u003c\/p\u003e\n\n\u003ch3\u003eAbout Crown Cryogenic Steel\u003c\/h3\u003e\n\n\u003cp\u003e\u003ciframe allowfullscreen=\"\" frameborder=\"0\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/_h5XyzNWy-4\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe 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°C which changes the molecular structure of the steel.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eThe cryogenic process greatly enhances and accelerates the austenic transformation.  Another benefit is that at these extreme temperatures, fine ‘eta’ carbides are formed within the carbon structure.  Growing very slowly and only at these very low temperatures, ‘eta’ carbides are extremely small and act as a ‘filler’ between the other crystals in the metal.\u003c\/p\u003e\n\n\u003cp\u003eThe combined effect of heat treatment and cryogenic processing is to produce a refined crystal structure in your hand tool that will give a lifetime’s service by producing a blade that will retain its edge longer and give a superior ‘feel’ in use.\u003c\/p\u003e\n\n\u003cp\u003eAll Crown Cryogenic Turning Tools are finished with beautiful black Ash handles.\u003c\/p\u003e\n","brand":"Crown","offers":[{"title":"Default Title","offer_id":45917227483303,"sku":"247-AKW","price":119.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/7287\/4151\/files\/620659-247-KW-2_20web.jpg?v=1723031172","url":"https:\/\/www.timbecon.com.au\/products\/crown-bead-parting-tool-6mm-m2-cryogenic-steel-woodturning-tool","provider":"Timbecon Pty Ltd","version":"1.0","type":"link"}
