Save Time and Increase Productivity

Our preform expertise allows for major portions of carbide to be removed while still in the green state. Compared to the hard state, drilling of coolant holes, prefluting, and grinding different diameters happens in a fraction of the time. We leave a minimal amount of grind stock which saves you grinding wheel life, and increases machine capacity. All of these features save you money. Blanks include:

  • Flats
  • Chamfers
  • Keyways
  • PCD Pockets
  • Preformed sharpening angles
  • Straight Flutes
  • Spiral Flutes
  • Coolant holes (in any location)
  • Stepped Diameters
  • Centers (male or female)
