Screwdriver Bit Set Wera BC 30 Diamond 1 30 pc(s)

The Wera BC 30 Diamond 1 is a 30-piece screwdriver bit set containing Phillips, Pozidriv and Torx tips with a 1/4" (25.4 / 4 mm) hexagonal shank. Bits feature tiny diamond particles on the tip for improved grip in the screw head and a BiTorsion elastic zone that diverts peak loads to reduce tip breakage and extend service life. The set includes a compact multi-component Bit-Check holder with colour-coded "Take it easy" tool finder for quick profile and size recognition and a Rapidaptor-compatible design for fast single-hand bit changes. The set is suitable for use with power screwdrivers and drills with a chuck.

Advantages

Diamond particles on the bit tips provide secure engagement with screws, lower contact pressure and reduce slipping. BiTorsion technology combines an elastic torsion zone and a softer BiTorsion section to absorb peak loads and prevent tip twisting under high strain, increasing durability. Rapidaptor compatibility allows tool-free bit attachment and easy one-hand removal by pushing the sleeve forward. The lightweight Bit-Check holder keeps bits compactly stored, holds them securely yet allows easy removal, while the Wera colour coding and clear imprint make profiles and sizes easy to identify.

Suitable for

• General assembly and repair work with Phillips, Pozidriv and Torx screws
• Use with power screwdrivers and drill chucks (1/4" hex shank)
• Professional trades and DIY projects requiring durable, anti-slip bits

How to use

Insert the required 1/4" bit into the screwdriver or drill chuck or into a Rapidaptor-equipped holder. For Rapidaptor users, attach the bit without actuating the sleeve and remove it by pushing the sleeve forward to release the bit for one-hand changes. Match the bit profile (Phillips, Pozidriv or Torx) to the screw head, apply steady axial pressure and drive at appropriate speed to avoid overloading. Store bits in the Bit-Check holder to keep them organised and protected.

Usage recommendations

Use the diamond-tipped bits where higher grip is needed to reduce cam-out; avoid excessive torque beyond the tool and screw ratings. Replace worn bits to maintain secure engagement and the protective benefits of the BiTorsion zone. Keep the Bit-Check free of debris to ensure reliable bit retention and identification.
