★ FAQ

Frequently Asked Questions

What materials can the 5%Cobalt HSS drill bit 3.75mm drill through? +
HSS (high-speed steel) drill bits cut mild steel, aluminum, plastics, and wood. They are NOT suitable for masonry, concrete, or hardened steel — use carbide-tipped or cobalt bits for those. Use cutting oil when drilling steel for better bit life.
Are these HSS or cobalt bits? +
Check the title — Ronix offers standard HSS (general steel/wood/plastic), HSS-G (ground, smoother cuts), HSS-CO (5% cobalt, for stainless and hardened steel), and HSS-TiN (titanium-nitride coated, 3× life). Match the bit grade to the material hardness.
What's the best drilling speed for steel with HSS bits? +
Approximate speeds: 6mm bit → ~1500 RPM in mild steel, 12mm → ~700 RPM, 20mm → ~400 RPM. Use slower speeds in stainless steel. Always use cutting oil to extend bit life and reduce work-hardening of the workpiece.
