RUKO SPB-TL3000 11,5 mm DIN 338 HSS-G špirálový vrták

Drilling precise holes in steel, cast iron, non-ferrous metals, plastics, and wood requires a drill bit that stays sharp and cuts cleanly. The RUKO SPB-TL3000 11.5 mm twist drill bit is fully ground from high-speed steel (HSS-G) to DIN 338, delivering reliable performance for general-purpose drilling tasks.

Who is it for

This drill bit is ideal for metalworkers, machinists, and serious DIYers who need a durable, accurate bit for everyday drilling in a range of materials. Its 11.5 mm diameter suits applications requiring a mid-size hole, such as clearance holes for M12 bolts or pilot holes for larger diameters.

Tips

Use cutting fluid when drilling steel or cast iron to extend bit life and improve hole quality. For plastics and wood, reduce speed to prevent melting or burning. Always secure the workpiece and wear appropriate eye protection.
