The first extra-long twist drill bit with stepped drill bit tip geometry
Precise, circular holes without centre-punching
Up to 100 % faster than conventional extra-long HSS drill bits
Extremely comfortable drilling
- Eliminates pre-drilling despite the extra-long design, precise spot drilling
- Prevents the tool from running off-centre even during particularly deep drilling
- Significantly less effort required when drilling compared to conventional extra-long twist drill bits
- Simple drilling or enlarging of an existing drill hole
3-flat shank
- No spinning in the drill chuck: faster, more comfortable working
- Optimal power transmission
- Protects the drill chuck from damage
- Minimal effort required to loosen and tighten the drill chuck
Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable
Available exclusively from Würth
For blind holes, please note the extended drill tip (see dimension l3)!
Datasheets(X)
- Ideal for drilling thin-walled composite materials, e.g. in window construction (plastic profiles with steel core)
- High quality of drill holes and significantly longer service life compared to conventional wood boring bits.
- Perfect for cordless drill drivers as well as handheld and pillar drill and drill presses
- Universally suited for smooth as well as rounded and uneven surfaces
For optimum drilling progress and to avoid jamming, use “pecking cycles” for large drilling depths.
