⚡ At a Glance
- • Cutting Quality: Clean, flat-bottomed holes thanks to a short centring tip and tooth-shaped peripheral kerf
- • Best for: Carpenters, cabinetmakers and DIYers needing accurate hinge and recess drilling in wood
- • Not ideal for: Drilling metal or very large diameter holes beyond its 12 mm size
Short centring tip with two main kerfs and a tooth-shaped peripheral kerf produces precise, flat-bottomed holes. Manufactured to DIN 7483G with a cutter hardness of at least 50 HRC, suitable for soft and hard woods, veneered wood and non-laminated chipboard.
Cleaner, flat-bottomed holes, thanks to short centring tip and peripheral kerf
Short centring tip includes two main kerfs and a tooth-shaped peripheral kerf to cut material evenly and reduce wandering during entry. The geometry isolates the central cut from the outer kerf so the bore finishes flat.
Accurate hinge cups and neat dowel seats become straightforward, reducing the need for hand finishing. Repeatable hole quality speeds up assembly and produces tidier visible work.
Longer cutter life, with a tooth-shaped design that reduces friction and heat
Tooth-shaped cutting edges limit the contact area with the wood, lowering friction and heat build-up during cutting. Manufacture to DIN 7483G ensures a cutter hardness of at least 50 HRC for wear resistance.
Less frequent re-sharpening or replacement keeps workshop downtime to a minimum. Users report the bit stays sharp after many cuts, maintaining consistent performance.
Straightforward compatibility, with an 8 mm shank for common chucks
Shank size is suitable for all drill drivers and bench drills that accept an 8 mm chuck, allowing secure clamping and stable rotation. No adapter required for compatible drills.
Quick to swap into standard drills and bench machines, enabling seamless transitions between tasks. Compatible fit reduces wobble, improving hole accuracy.
