Annular Cutters and Carbide-Tipped Hole Saws

CS Unitec's annular cutters and carbide-tipped hole saws produce holes 3x faster than twist drills and leave clean, burr-free holes. Flutes run the length of the cutter for efficient chip clearance, less chatter, decreased cutter breakage and increased drilling productivity without pre-drilling or step-drilling. Annular cutters are available in hardened High-Speed Tool Steel, Titanium Aluminum Nitride (TiAlN), Tungsten Carbide, Carbide and Cobalt.

Benefits of CS Unitec’s Annular Cutter Design:

  • Double-action tooth geometry cuts, splits and ejects chips more efficiently
  • More accurate holes with increased cutting speed
  • Minimmized tooth load and tool wear for long life
  • Tapered inner wall for smooth, easy slug ejection
  • Center pilot pin for internal lubrication and slug removal

Adapters and extensions available to fit most drill and magnetic drill models on the market.
