Rubi M14 chamfer drill bit for regrinding and refining drill holes in tiles, porcelain stoneware and ceramics
06985: round diamond chamfer drill / finger cutter
06987: conical diamond bevel drill bit
Perfect addition to any drill bit SET.
Especially for enlarging or changing the diameter and shape of a previously drilled hole. Also ideal for smoothing, polishing or cleaning the inner edges of previously drilled holes.
The diamond particles are bonded to the bit body using vacuum soldering technology. The high diamond concentration ensureshigh resistance to friction and temperature. The diamond particles used in the grinding tools have a grain size of #50/60.
The body of the round finger burr is perforated to improve cooling during grinding work.
Thanks to their M14 threaded connection, the burrs can be used with all grinding machines on the market at speeds between 6,000 and 11,000 rpm.
NOTE:
Diamond grinding bits are NOT suitable for drilling holes
