Benefits

• Consistent quality: Multiple bits of the same spec help manage wear and replace without shifting performance.
• Reduced start error: Step-point geometry helps ensure holes start where you want them, reducing rejects.
• Cost efficiency: Pack format lowers per-bit overhead and ensures you won’t run out mid-job.
• Versatility: Works well across a range of materials including soft metals, plastics and light alloys.

Extra Information

• Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat and prolong life.
• Begin with moderate RPM and feed; avoid excessive force which can deflect or break the bit.
• When drilling thin sheet, back up with scrap to prevent breakout on exit.
• Rotate usage among bits to balance wear and extend the life of the pack.

Specifications

Safety

• Wear eye protection — chips and small fragments can fly during drilling.
• Secure the workpiece firmly; avoid drilling handheld where slippage is a risk.
• Keep speeds and feed moderate — don’t force the bit.
• Use coolant or periodic breaks to avoid overheating the bit and workpiece.
