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
