Benefits of the Double Cut (DC) flute include rapid removal of a broad range of materials combined with excellent operator control. It does this by incorporating a positive 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. The steel shanks are ground, which sets them apart from our competitors. The solder joints are clean, with no excess solder gaping out from the sides between the carbide bud and the shankApplications:To be used with air or electrically driven hand die-grinder with a typical collet mechanism or knee mill with an air-driven spindle speeder such as an Air Turbine product. Use of a quality spindle speeder may greatly improve performance of miniature tooling.
