Features
The new bit-check generation from Wera
Utilising a unique combination of special material, hardening and precision manufacture
BiTorsion bits are designed to prevent premature wear and dramatically extend service life.
The patented Torsion zone absorbs peak stress loads that normally destroy bits.
Extra-tough bits suited to hard, metal jointing, threaded fasteners and general use.
The holder with quick-release chuck offers press-in auto-lock and rapid one-handed bit changes for insert and power bits.
The holder spin sleeve allows the steadying of the screwdriving
BiTorsion Diamond Coated (BDC) bits ensure safe working, especially driving screws into delicate materials or high-quality surfaces, preventing slipping.
Additionally, where screws are driven into resistant materials such as hard woods, concrete screws and ABS plastics diamond coated bits 'bite' into the fastener ensuring a secure fit and reducing cam-out effect.
This extends the life of the tool and ensures screws are fully driven home.
Comes in a fantastic easy to carry in the pocket outer case
For use with drill drivers (NOT FOR USE IN IMPACT DRIVERS)
