  • Application
  • Item Features
For use on grinding and finishing applications
  • Super premium 118 deg split point drill bits - bronze oxide (gold) finish
  • Made from heavy duty high molybdenum, hardened steel for increased consistency and greater wear resistance
  • Flutes are ground to extremely tight tolerances for increased accuracy and consistency in the point and split grinding process, resulting in more accurate hole sizes
  • Flutes have a thin nitro carburized surface to provide extra wear resistance along the cutting edge of the point
  • Special flute form enhances chip ejection, reduces drill retractions (wood peckering) and improves coolant flow to the tip
  • Split point provides the drill with self-centering/non-walking characteristics by giving the drill two starting points
  • Split point also reduces the thrust required to penetrate the workpiece
  • The superior bronze oxide (gold) ground flute finish reduces friction, allowing outstanding drilling performance with less operator pressure
  • JET offers Torque Drive® three ground flats on the shank to provide a strong positive chuck grip virtually eliminating the potential for the drill to slip in the chuck
  • The thin web of the JET-KUT® Gold prentice bit permits fast feed rates which make it ideal for drilling work on hardened steels such as 304, 306 and 316 stainless steel
