SST+ 135° 1/2" Prentice

For high tensile steel, fits in a 1/2” chuck

SST+ ½” Prentice are heavy-duty large diameter drill bits for use in portable drills, drill presses and magnetic base drills with ½” chuck capacity. Their extra hard tips allow for the drilling of many more holes between re-sharpenings. They are made with a cobalt blend for longer life.

Features

  • 3 flats on shank prevent slippage inside chuck
  • Drills more holes, faster
  • Exclusive point geometry eleminates pre-drilling
  • Special bronze SST surface treatment

Materials

  • Mild steel
  • Non-ferrous metal
  • Stainless steel
