Drill fi 1,2 with cylindrical shank
HSS DIN 3381.2 mm metal drill bit is designed for drilling nominal holes in structural steels, cast iron and non-ferrous alloys; in workshop applications, used m.in. as a fi 1.2 mm metal drill bit, it maintains dimensional repeatability in IT12 grade.
The working diameter is 1.2 mm; the 118-degree tip angle ensures smooth entry and even blade loading. Spiral, precision-ground grooves promote consistent chip evacuation in the right cutting direction. The core made of high-purity homogeneous high-speed steel maintains edge sharpness and wear resistance. The length design corresponds to the normal length according to DIN 338, and the cylindrical shank works with standard chucks. Process stability is supported by high speeds, micrometer feed, precision clamping and emulsion or oil mist cooling - in typical operations for a 1.2 mm metal drill. The drills are designed for conventional lathes, milling and drilling machines, as well as specialized computer-controlled numerical control machine tools.
- Stable axis start - 118-degree geometry reduces drift and organizes the drilling path.
- Even wall surface - polished chip channels reduce friction, lowering roughness and risk of burrs.
- Repeatability of IT12 grade - dimensional retention is ensured by proper parameters and rigid clamping, as confirmed by the fi 1.2 mm drill bit for steel in batch and unit machining.
- Edge durability - homogeneous HSS extends the service life between sharpening.
Compliance with DIN 338 and reference to PN-EN ISO 286 enable qualification of the holes obtained for workshop fits; thus, predictable diameter, alignment and stable hole geometry are maintained in typical micromachining tasks.
