⚡ At a Glance
- • Cutting Quality: 118° point edge, manufactured to DIN 7490, for cleaner starts and neater holes
- • Best for: Builders, carpenters and installers working on formwork and multilayer materials
- • Not ideal for: Heavy-duty masonry or hammer-drilling in reinforced concrete
Extra-long HSS shank, 6mm diameter with 600mm overall length for deep drilling. Manufactured to DIN 7490 with a 118° point edge and compatible with drills that have a 13mm chuck.
Reach deep cavities – with 600mm extra-long shank
A 600mm overall length places the cutting tip well beyond standard bit reach, while high-speed steel construction helps keep the shank rigid over long spans. The extra-long shank is designed specifically for formwork and sandwich materials where access is otherwise restricted.
Access deep voids and pass through multilayer panels without extensions, reducing time spent swapping tools during interior fitting, plumbing, heating and electrical runs.
Accurate starts and cleaner holes – thanks to DIN 7490 118° point edge
A 118° point concentrates the cutting action at the tip for a reliable centre and reduced walking at contact. Manufacture to DIN 7490 ensures a consistent point geometry across production batches.
Begin holes confidently on wood, plasterboard and thin metals, producing neater finishes and less tear-out for follow-up fitting or fixings.
Versatile across materials – with HSS construction and 13mm chuck compatibility
High-speed steel tolerates higher temperatures and offers a balance of hardness and toughness suitable for cutting wood, plastics and thin metals. Compatibility with drills that accept a 13mm chuck means a wide range of handheld drills can accept the shank.
Use one bit for formwork, boards, profile sheet and lightweight metal plates, keeping kit simpler for on-site trades.
