Amana Tool Ball Shape 3/8" D x 5/16" CH x 1/4" Shank Double Cut SD Burr Bit for Die-Grinders – 6 3/4" Long

Thank you for shopping with us!

Double Cut (DC) burrs utilize a cross flute of exactly half the number of standard flutes in an opposing helix. Benefits include rapid removal of a broad range of materials combined with excellent operator control. It does this by incorporating a cutting rake angle that gives great " bite" into the material, and yet is not so aggressive that the operator fatigues quickly after using it in a hand piece. A DC flute geometry gives better performance in low RPM applications, but still performs well at high RPMs.

Applications: To be used with air or electricity-driven hand die-grinder with a typical collet mechanism or knee mill with an air-driven spindle speeder such as an Air Turbine product. An air speeder can bump spindle.

(Carbide brazed to steel shank.)
