Ø0.5 metal drill bit with a straight shank
0.5 mm metal drill bit HSS DIN 338 is used for precision drilling of microholes in structural steels, cast iron, and nonferrous alloys; in practice, also used as a Ø0.5 mm metal drill bit, it maintains a stable cutting path and accuracy within IT12 tolerance grade.
The nominal diameter is 0.5 mm. The 118° point angle supports reliable entry into the material, while ground helical flutes ensure consistent chip evacuation during right-hand cutting. The homogeneous, high-purity high-speed steel (HSS) core provides wear resistance and lasting cutting edge sharpness. The length conforms to DIN 338 (jobber length), and the appropriate slenderness ratio promotes process stability. The drill bits are designed for conventional lathes, milling machines, and drilling machines, as well as specialized computer numerical control machine tools.
- Repeatability of IT12 tolerance grade — dimensional stability is demonstrated by a Ø0.5 mm drill bit for steel with properly selected speeds, feed, and rigid clamping.
Precise entry and axial alignment — the 118° geometry reduces wandering and stabilizes the start of drilling. - Even hole wall surface finish — polished flutes reduce friction, promoting low surface roughness and a clean exit edge.
- Cutting edge life — homogeneous HSS extends operating time between resharpenings in single-part and short-run production.
Compliance with DIN 338 facilitates mounting in standard chucks, and the resulting holes qualify for IT12 workshop fits according to PN-EN ISO 286; as a result A Ø0.5 mm metal drill bit ensures a predictable diameter, maintained axial alignment, and stable microhole geometry.
