Key Features & Benefits
- Patented step-tip — eliminates pilot drilling for 15-20mm holes — straight to size in one plunge.
- 12.7mm reduced shank with 3-flat grip — fits any 13mm chuck and resists slipping under heavy thrust.
- Black-oxide finish — holds cutting fluid on the flute and improves chip flow and heat dissipation.
- Bonus Alpha Liquid Gold cutting fluid — 250ml of premium cutting lubricant included — extends bit life on stainless and high-tensile steel.
- Tuffbox Pro storage — reinforced site case keeps the set organised on the truck or job.
When to Use This Set
Use this set when you need to drill 15-20mm holes in steel plate, structural section or stainless and you only have a 13mm-chuck drill. The step-tip + reduced shank combination saves the pilot-drill step and the chuck-swap that big bits normally need.
