RUKO HSS drill bits, pack of 10, self-centering, Ø 3.5 mm, extra short and ground.

The Ruko-251035 drill bit is a pack of 10 extra-short HSS (High-Speed Steel) entry drill bits, specifically designed to offer optimal performance in assembly work on thin-walled materials. Shorter than the DIN 1897 standard, these drill bits are ideal for drilling sheet metal, flat and profiled iron, guaranteeing high resistance to breakage. Their design allows for efficient use in hand drills, facilitating work in confined spaces.

The drill bits feature a tapered point with a split point, conforming to DIN 1412 C, which ensures good centering and requires little pressure during drilling.
