Cyclone Premium Annular Cutters are available in stock for immediate delivery. Available in 2 depth sizes: 25.4mm (short) and 50mm (long) and range from 12mm to 65mm diameters.
Cyclone Premium Annular Cutters are made of S630 Tungsten-molybdenum high speed steel with an aluminium alloy. Tough with excellent cutting properties, for a wide variety of uses. They can be heat treated up to 68 RC and they still have tempered hardness and are guaranteed to outperform annular cutters made out of HSS, Cobalt, or Tini Coated Cutters. This is because...
The Tini Coating on HSS annular cutters increases the cost of the cutter but only enhances the cutter's appearance.
HSS M-2 Annular Cutters can only be heat treated up to 64 RC before they become too brittle.
Cobalt Annular cutters can only be heat treated up to 66 RC before they become too brittle.
A higher RC rating without brittleness means more holes cut per sharpening.
