Usage
Designed for precise drilling in both alloyed and unalloyed steels, cast iron, sintered iron, non-ferrous metals like aluminum and copper, as well as tough plastics. Ideal for workshop and maintenance applications requiring clean, accurate holes in metal.
Advantages
- Manufactured from high-speed steel (HSS) with titanium nitride coating for increased surface hardness and reduced friction.
- Twist drill geometry in accordance with DIN 338 ensures optimal chip removal.
- Split point tip at 135° allows easy centering and minimizes wandering on hard materials.
- Straight shank sized to fit standard drill chucks for reliable power transfer.
- The titanium coating prolongs tool life but requires use of coolant during drilling to ensure durability.[1][3]
Specifications
- Straight-cut twist drill made from fully ground HSS according to DIN 338; bright gold finish due to the titanium nitride layer.[1][3]
- Titanium nitride coating enhances wear resistance; cross-ground tip manufactured per DIN 1412C tolerances.[1]
- Total length: approximately 109 mm; usable flute length: about 69 mm; diameter: Ø7.5 mm.[3]
- Suitable for materials up to a tensile strength of max. 900 N/mm² (MPa); precise diameter tolerance maintained by advanced grinding process.[1][3]
How it works
The bit is mounted into a compatible drill; its sharp split-point geometry starts cuts precisely while two flutes evacuate chips efficiently. Titanium nitride reduces friction and requires the use of cooling fluid when drilling hard metals or operating continuously.[1][3]
