Description

  • Four large right spiral polished flutes permit higher feeds and speeds
  • Carbide tips brazed to hardened tool steel body
  • 118º included chamfer angle
  • Rigid design provides maximum support for the carbide tips
  • Tool diameter tolerance: plus .000", minus .001"

Options

  • Modified tool diameter
  • Modified metric tool diameter
  • Closer tool diameter tolerance
  • End chamfer other than 118º included angle
  • End cutting or corner radius
  • Shortened shank or reduced shank diameter
  • Flat(s) or tang on shank
Coatings available:
  • TITANIUM NITRIDE - TiN
  • TITANIUM CARBONITRIDE - TiCN
  • ZIRCONIUM NITRIDE - ZrN
  • AL TITANIUM NITRIDE - AITiN

Use

  • Designed for economically enlarging cored, punched, or drilled holes - can remove up to 30% of the tool diameter
  • The balanced cutting action of the core drill removes considerably more material than a reamer, often eliminating the need for a final reaming or boring operation
