  • The Wera Bit-Check 12 Diamond 1, with Rapidaptor is designed for compact and organised tool storage.
  • 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. 
  • 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.
  • Wera Bit-Checks feature a compact design to safely store bits and bit holders in a case that provides fast and easy tool selection.
  • It is so slim that it can fit into your pocket. 
  • Drive and size are colour coded for easy selection of the right bit.
  • 1 x 1/4" x 50mm Rapidaptor Universal bit holder.
  • 3 x BiTorsion 25mm BDC Phillips bits: PH1, PH2 (x2).
  • 3 x BiTorsion 25mm BDC Pozidriv bits: PZ1, PZ2 (x2).
  • 5 x BiTorsion 25mm BDC TORX® bits: TX10, TX15, TX20, TX25, TX30.
