Drill fi 1 with cylindrical shank
HSS DIN 3381 mm metal drill bit is designed for drilling nominal holes in structural steels, cast iron and non-ferrous alloys; in workshop realities, also used as fi 1 mm metal drill bit, it provides a stable cutting path and maintains the IT12 grade dimension.
The nominal diameter is 1 mm. The 118-degree apex angle balances cutting forces and facilitates a smooth entry into the material, while helical, precision-ground grooves promote continuous chip evacuation in the right cutting direction. The drills are designed for conventional lathes, milling and drilling machines, as well as specialized CNC-controlled machine tools. The high-purity high-speed steel core is characterized by wear resistance and edge stability. Length execution according to DIN 338 (normal length) and cylindrical shank are conducive to work in standard chucks. Emulsion or oil mist cooling, micrometer feed, high RPM and rigid clamping are recommended.
- Secure entry into the material - 118-degree geometry reduces drift at the start and stabilizes the drilling axis.
- Repeatable IT12 grade - dimensional stability maintains fi 1 mm drill bit for steel with properly selected speeds, feed and rigid clamping.
- Uniform hole surface - polished chip channels reduce friction, which promotes low wall roughness.
- Edge durability - homogeneous high-speed steel slows wear in unit and short-run cycles.
Compliance with DIN 338 and reference to EN ISO 286 enable the holes obtained to be qualified for workshop fits; consequently, the fi 1 mm metal drill provides predictable diameter, alignment and a clean exit edge in typical micromachining tasks.
