Diamond drills
-
Galvanic hollow drill bit
Because the drill bit is made completely of diamond granules, the life-time compared to other only coated (and that sparsely) diamond bits is hundred-fold higher, because the drill can be used till the end.
(A merely coated drill is worthless once the few diamond granules at the front side are broken out.)
The shaft is cylindrical with the respective drill diameter.
Drill length approximately 30..40 mm.
Can be clamped into every chuck.
Without holder and ejector.
