## Long description

Single Wera Torx T20 867/1 BDC SB SiS screwdriver bit made of alloyed tool steel with diamond coating. The bit is designed for use with 6.3 mm (1/4") bit holders and screwdrivers and features a BiTorsion (BDC) design with a softer torsion zone that reduces shaft hardness by about 20% compared with the tip. This construction reduces tip deformation under peak loads and extends the service life of the bit while the diamond coating improves grip in the screw head and reduces cam‑out.
Advantages
The BiTorsion design minimizes transient overloads during machine or powered fastening, preventing premature wear of the bit and reducing the risk of screw damage. Diamond coating embeds tiny abrasive particles on the tip surface to bite into the screw head for improved slip resistance without damaging the screw. Together these features increase tool life and productivity in repetitive fastening tasks.
Suitable for
 Machine and powered fastening with 6.3 mm (1/4") bit holders
 Professional assembly and industrial production environments
 DIY and repair tasks requiring reliable torque transfer and reduced cam‑out

How to use
Insert the T20 bit into a compatible 6.3 mm (1/4") bit holder or screwdriver chuck until it locks. Use the bit with appropriate torque and speed settings for the screw type and material. The BiTorsion zone will absorb torsional peaks during powered fastening; avoid excessive bending or side loads on the bit. Replace the bit when signs of wear appear to maintain fastening quality.
Usage recommendations
Use the bit primarily for machine or powered applications where repeated fastening occurs. Match torque settings to the screw and workpiece to avoid overstressing the bit. Store the bit dry and clean to preserve the diamond coating and inspect regularly for wear.
