The new  coated dowel drills developed by Sistemi in order to put on the market an higher level of dowel drills compare to all the others we have seen on the market so far.

Thanks to their longer tool life, up to 4 times better than the same uncoated bits, and their productivity up to 6 times better, the  are considered the most economic dowel drills for automatic machines on the market, considering the less number of grindig operations, thus less downtime for changing tool.

The diamond like carbon (DLC) coating makes the  dowel drills the best choice when working with hard and abrasive material, hard wood, chipboad and laminated panels, Trespa and melamine.

EXTRA PERFORMANCE - EXTRA TIME -
