   of the material and the formation of
   “microcracks.”

	Proper cleanliness and filtration of
   coolants is important in order for
   the coolant to maintain its beneficial
   properties, and also to avoid a
   reduction in coolant pressure or the
   possibility of clogging the coolant
   channels in coolant through drills.

	Reducing the nozzle size helps maximize the cooling benefits of the unique double margin design on the Hi-PerCarb drill
   by increasing velocity. Aim the nozzles in line with the secondary flute located between the two margins as well as the
   flute for best results.
