The complex geometry of a drill bit point makes it very hard to free hand sharpen it correctly. The Drill Bit Sharpening Attachment DBS-22 makes it possible to sharpen drill bits on your Tormek Water Cooled Sharpening System with the highest precision. You create a 4-facet point which gives the ideal cutting performance. The optimal point and clearance angle can be set according to each drilling requirement in regards to drill size and material. You can restore completely worn drills as well as broken drills to a perfect shape.
Unlike conventional drill bit sharpeners, Tormek sharpens with water cooling which is gentle on the steel. Overheating of the steel is usually not noticeable, but the consequences are that the drill will dull rapidly and may even break. 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.
With a 4-facet sharpening 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. It generates less heat and the life of the drill is therefore also prolonged. The attachment can be set at any point angle between 90° and 150° and at four different clearance angles. This flexibility enables you to give the drill the geometry that works best for each drilling operation. You can for example minimize the burr, which occurs on the exit side of a drilled hole by increasing the point angle and decreasing the clearance angle.
The drill holder as well as the guides are made with the highest precision to ensure that the lengths of the two cutting edges will be equal within close tolerances. This is an essential requirement so that the cutting edges will work equally and bore a round, straight hole, which is not larger than the drill diameter. Copes with drills from 3 mm (1/8") to 22 mm (7/8"). Fits all Tormek models.
