Tips

For best results, use a center punch to mark the drilling location, especially on hard metals. Apply cutting fluid to reduce heat and extend bit life. Use appropriate speeds: lower RPM for steel, higher for non-ferrous metals. Ensure the drill bit is securely tightened in the chuck to prevent slippage.
