- Item Features
- Application
- Constructed of M-2 high speed steel for the best combination of strength, heat resistance and wear resistance
- Black oxide/gold provides a polished finish and prevents chip building, galling and welding on a workpiece
- It is commonly used in several applications on low carbons, stainless steel and iron based ferrous metals
- Round shanks with flats are ground flat on three sides for increased chuck grip, reducing slippage and help centering the drill in the chuck
- They are used with portable drills and drill presses on ferrous and non-ferrous materials
- 3-flatted shank design provides better chuck grip and reduces slippage
- Ideal for use in keyless chucks
- All Silver & Deming bits are 6 in long and feature a 1/2 in reduced shank that fits all 1/2 in drills
- 1/2 in reduced shank with 3-flats grips securely
- Standard 118 deg point for use in wood, metal and plastic
- 118 deg conventional point is not self centring
- Best for stationary drills
- Performs better in softer materials vs hard metal
