A 100% increase in tool life is the main benefit claimed for Guhring’s Wave Form straight shank drills.
The Wave Form is ground on to the point and into the flutes, which weakens the chips on the point and breaks the chips into flutes. This increases performance as the cutting process is easier and cutting forces are reduced. It offers improved coolant delivery and retention and short chips, even in long-chipping materials which are difficult to machine.
The drills are available in stub or jobber lengths, bright finish, TiN or Movic coating, and in standard GT100 (deep hole) or stainless steel flute design.
