RUKO LOS-HSS-G 15,0 mm kierreporanterä HSS-G DIN 338

Precision drilling in metal demands a bit that stays sharp, runs true, and clears chips efficiently. The RUKO LOS-HSS-G 15.0 mm twist drill bit is ground from solid high-speed steel (HSS-G) to DIN 338, delivering clean, accurate holes in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics. Its bright, uncoated finish and 118° point angle provide reliable cutting performance for general-purpose workshop and maintenance tasks.

Who is it for

This drill bit suits metalworkers, maintenance technicians, and serious DIYers who need a durable, full-size 15 mm bit for handheld drills or pillar drills. It is ideal for creating precise holes in steel plates, profiles, and machine components where a standard twist drill is required.

Tips

Use a cutting fluid or lubricant when drilling steel to extend bit life and improve hole finish. For deep holes, withdraw the bit periodically to clear chips. Ensure the drill is securely chucked and run at appropriate speed for the material.
