Disable hammer action immediately when drilling metal—this aggressive mechanism will shatter bits and tear through metal unpredictably. For clean, precise holes, use sharp cobalt or titanium-coated bits at slow speeds with cutting fluid, applying steady, moderate pressure to prevent overheating.
This is a comprehensive guide about hammer drill metal drilling tips.
Key Takeaways
- Disable hammer function: Turn off hammer mode to prevent metal damage and ensure clean holes.
- Use sharp metal bits: Choose high-speed steel or cobalt bits designed specifically for metal drilling.
- Lubricate for longevity: Apply cutting fluid to reduce heat and extend bit life.
- Apply steady pressure: Use moderate, consistent force rather than excessive pressure that could break bits.
- Secure your workpiece: Clamp metal firmly to prevent slipping and ensure accurate drilling.
- Start with a pilot hole: Begin with a small pilot hole for better accuracy on larger holes.
- Clear chips regularly: Retract the bit frequently to remove metal shavings and prevent binding.
