RUKO SPB-TX-DIN338-HSS-TiN-Ø9.0mm Twist Drill Bit

Drilling precise holes in tough materials demands a bit that stays sharp and resists wear. The RUKO SPB-TX-DIN338-HSS-TiN-Ø9.0mm twist drill bit solves this by combining high-speed steel with a titanium nitride coating, delivering clean cuts in steel, cast iron, and non-ferrous metals.

Who is it for

Tips

Use a cutting fluid or lubricant when drilling steel to extend bit life. For best results, start with a center punch to prevent walking, and apply steady, moderate pressure at low to medium speed.
