RUKO HSS drill bits, pack of 10, self-centering, Ø 2.5 mm, extra short and ground.

The Ruko-251025 drill bit set is a pack of 10 extra-short HSS (High-Speed Steel) face drill bits, designed to deliver exceptional performance in assembly work on thin-walled materials. Shorter than the DIN 1897 standard, these bits are ideal for drilling sheet metal, flat and profiled iron, ensuring high resistance to breakage. Their design allows for efficient use in hand drills, facilitating work in confined spaces.

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