Ø0.7 metal drill bit with a straight shank
0.7 mm metal drill bit HSS DIN 338 is designed for precision microdiameter machining in structural steels, cast iron, and nonferrous alloys; in workshop applications, it also performs well as a Ø0.7 mm metal drill bit, providing a stable cutting path and maintaining dimensions within tolerance grade IT12.
The nominal diameter is 0.7 mm. The 118° point angle facilitates centering and even loading of the cutting lips, while the precision-ground helical flutes ensure continuous chip evacuation with right-hand cutting. The core of homogeneous, high-purity high-speed steel increases wear resistance and edge stability. The length corresponds to the standard length according to DIN 338; under these conditions, when drilling as a Ø0.7 mm drill bit for steel, it is easier to maintain workshop diameter tolerances at high spindle speeds, with micrometer-scale feed, rigid clamping, and cooling with emulsion or oil mist. The drills are designed for conventional lathes, milling machines, and drilling machines, as well as specialized computer-controlled CNC machine tools.
- Stable centering — the 118° geometry reduces wandering on entry and stabilizes the drilling path.
- Smooth hole surface — polished flutes reduce friction, promoting low hole wall roughness.
- Edge durability — homogeneous high-speed steel provides consistent tool life in one-off and short-run production cycles.
- Repeatability of IT12 tolerance grade — dimensional consistency supports Ø0.7 mm metal drill bit with properly selected speeds and feed, and rigid clamping.
Compliance with DIN 338 facilitates mounting in standard chucks, and the resulting holes meet workshop fit requirements in tolerance grade IT12 according to PN-EN ISO 286, maintaining a predictable diameter, axial alignment, and a clean exit edge.
