Significantly longer service life compared to conventional auger drill bits
- Special surface treatment
- Offset drill head
- Specially adapted taper tap geometry
- Newly developed thread tip
Ideal in softwoods and all hardwoods (even in exotic hardwoods, such as Azobé/Bongossi)
Newly developed thread tip
Minimum force required due to independent feed with even less friction
New edge geometry
Perfect chip removal and directional stability for deep holes
Optimised spiral flute geometry
Hexagon shaft (above 7 mm diameter)
- No twisting in the drill chuck: faster, more comfortable working
- Optimum transmission of forces
- Protection of the drill chuck from damage
- Little effort required to open and close the drill chuck
Saves time
By using the Würth push-on countersink (above 12 mm diameter), drilling and countersinking are possible in one work step
Larger effective lengths
The Würth extension can be used from a diameter above 22 mm
Available exclusively from Würth
Datasheets(X)
The auger drill bit LONGLIFE & SPEED can be used either hand-guided or stationary (e.g. in CNC machining centres, timber framing centres) for the fast drilling of dimensionally accurate, deep holes in wood (e.g. rafters, beams). The cutting values in the speed table must be observed in this regard depending on the material.
