kwb 248660 HSS-R kierrep pora 6 mm DIN 338, brunattu, 1 kpl

Drilling precise holes in metal requires a bit that stays sharp and cuts cleanly without wandering. The kwb 248660 HSS-R twist drill bit solves this with a rolled high-speed steel body, a 118° point angle, and a black oxide finish that reduces friction and improves chip flow. Its DIN 338 dimensions ensure a standard 93 mm overall length and 57 mm flute length, making it compatible with most drill chucks and ideal for general-purpose metalworking.

Who is it for

This drill bit is built for metalworkers, maintenance technicians, and serious DIYers who need reliable performance in steel, cast iron, non-ferrous metals, and plastics. Whether you are drilling mounting holes, preparing for tapping, or doing light fabrication, the 6 mm diameter covers a wide range of common tasks.

Tips

Use a cutting fluid or light oil when drilling steel to extend bit life and improve hole quality. For best results, start with a center punch to prevent walking, and reduce feed pressure as the bit exits the workpiece to avoid burrs.
