9/16" X 1" Annular Cutter - 6% Cobalt

These unique cutters reduce time and power requirements by cutting larger diameter holes at the periphery leaving solid slug in the center.

Our high speed steel cutters contain high tungsten content to increase abrasion resistance resulting in a tough tool with long lasting durability. In addition to an already great tool we add 6% Cobalt on top to increase heat resistance. This M35 Cobalt Cutter has a gold finish and is designed for increased hardness for tough jobs. 

  • Give the lowest cost per hole
  • Cut on curved surfaces 
  • Allow overlapping cuts on existing holes
  • Stay sharp much longer
  • Leaves a burr-free hole
