High Helix cut for use on:
Aluminum, Magnesium alloy, Plastics, Hard rubber, Zinc alloy.

For best results use with OptiCut-NF Lubricant or Wax Stick.

The high spiral design of these burrs allows more continuous contact between the tool's cutting edges and the work piece. The improved shearing action minimizes vibration and bounce - resulting in a cutter that provides more control, fast stock removal and improved surface finish.
