RUKO ERB-HSSCo pistehitsauspora 6,35 mm A4-L:lle

Removing spot welds from high-strength steel and stainless steel sheet metal is slow and destroys ordinary drill bits. The RUKO ERB-HSSCo 6.35 mm spot weld drill bit is made from high-speed steel cobalt (HSSCo) with a 135° split point that self-centers on the weld and cuts cleanly without walking. The short 45 mm overall length and 12 mm flute length provide the rigidity needed for controlled drilling in automotive body repair and metal fabrication.

Who is it for

Auto body technicians, metal fabricators, and maintenance crews who regularly remove spot welds from sheet metal and need a drill bit that resists heat and wear in tough materials.

Main features

• High-speed steel cobalt (HSSCo) for high heat and wear resistance

Tips

Use a center punch to mark the weld before drilling to help the split point engage. Apply cutting fluid when drilling stainless steel to extend bit life. Drill at moderate speed and pressure; let the bit do the work.
