Usage
The HSS Ø12.5mm drill bit is designed for precision drilling in unalloyed and alloyed steels, cast iron, and other metals up to 900 N/mm². It is suitable for workshops, maintenance tasks, and industrial settings.
Advantages
- Makes clean, accurate holes in a wide range of metals
- High resistance to heat buildup during extended drilling sessions
- Flexible construction reduces breakage risk under moderate stress
- Suits both handheld drills and drill presses due to standardized design
- Requires periodic sharpening for optimal performance over time[7]
Specifications
- Material: High-speed steel (HSS), DIN 338 standard[3][5]
- Point angle: Typically ground at 118°, ensuring effective cutting in metal[1][5]
- Total length: Approximately 151 mm; flute length about 101 mm (tolerance may vary by manufacturer)[3]
- Cylindrical shank compatible with standard chuck systems[6]
How it works
This HSS drill bit operates by spinning at moderate-to-high speeds while the sharp cutting edges remove material from metal surfaces. Use appropriate pressure and speed settings based on the workpiece hardness to extend tool life and achieve precise results.[1][7]
