With the Tormek drill bits sharpening attachment DBS-22 we can now sharpen our drill bits (3-22 mm) with the highest precision. The optimal point can be set according to each drilling requirement, which depends upon the drill size and material. we can completely restore worn drills as well as broken drills to a perfect shape.

4-Facet Point : We create a 4-facet point which gives the ideal cutting performance since the chisel edge gets a point instead of being almost flat as on many drills. A 4-facet point will not walk and the thrust force required is considerably reduced compared to a conventional cone point drill. A precision sharpened 4-facet point generates less heat and the life of the drill is therefore also prolonged. Independent tests show that a tormek sharpened drill lasts up to 4 times longer than a brand new conventional drill bit. Uddeholm tooling ab, 2010. 15 mm deep holes were drilled in toughened steel with 6 mm drills. With rotation speed 1326 R.P.M and 0.15 mm feed per rotation, the Tormek sharpened drills lasted on average 327 holes while the new drills with an s-shaped point lasted 72 holes
Controlled Sharpening : By working with the laws of physics and cooling the edge continuously, the risk that the steel becomes overheated and loses its hardness or gets micro cracks is eliminated. we have full control all the time and can see how the sharpening proceeds
