- Size: Ø3.00 mm x 10.00 mm overall length
- Tip geometry: 118° pilot with a 60° cone for stable centering and accurate hole starting
- Material: Premium HSS-E suitable for drilling steel, aluminium, and stainless steel
- Finish: Bright finish helps prevent material sticking to the cutting edge
- Double-ended design: Two drilling ends extend tool life and boost productivity
- Long-series: Extended reach ideal for deeper center holes and longer shafts
When starting holes in shafts or precision parts, this centre drill delivers true alignment and clean starts, minimizing wander and improving subsequent machining operations. The dual-ended design means you get more usable life from a single tool, reducing downtime and replacement costs. Made from premium HSS-E, it performs consistently across a range of materials—steel, aluminium, and stainless steel—while the bright finish helps reduce buildup on the cutting edge. The longer 10 mm reach is particularly valuable for deeper center holes and applications where space is limited, allowing secure holding and accurate centering in fixtures and chucks.
