Drill Bit Sharpening Attachment
With the patented Tormek Drill Bit Sharpening Attachment DBS-22, you can sharp-
en your drill bits with the highest accuracy. It copes with drills from 3 mm (
1/8
"
) to
22 mm (
7/8
"
) and with point angles from 90° to 150°. The optimal clearance angle
can be set to 7°, 9°, 11°or 14° according to the drill size and type of material to be
drilled. Water cooling eliminates overheating and micro cracks and at the low RPM
you have full control over the grinding operation. No dust or sparks are produced.
The drill is ground with a
4-facet point
, which
gives very good cutting performance. 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 prolonged. The 4-facet geometry causes
the drill to bore a straighter and rounder hole with
closer tolerances.
All the components are made with high precision
which ensures that the lengths of the two cutting
edges will be equal within close tolerances. This
is an essential requirement so that the two edges
will work in the same way and so that the drill will
bore a round, straight hole, which is not larger
than the drill diameter.
