Wera 05057750001 conjunto de 20 bits de aparafusar com revestimento de diamante com suporte universal, encaixe sextavado de 1/4 polegada, comprimento 25 mm

This 20-piece screwdriver bit set from Wera delivers a comprehensive range of diamond-coated bits in a compact Bit-Check case, engineered for maximum grip and reduced cam-out in demanding fastening tasks. The set includes Phillips, Pozidriv, Torx, and Hex-Plus profiles, each with a torsion zone to absorb peak loads and extend bit life. A universal bit holder with retaining ring ensures secure bit retention and quick changes, making this set ideal for both power tool and manual applications.

Advantages

Diamond coating on the bit tips creates a micro-rough surface that bites into screw heads, virtually eliminating cam-out and reducing the required contact pressure. The torsion zone effectively cushions load peaks, protecting the bit from premature wear and breakage. Hex-Plus geometry offers a larger contact area in hex socket screws, preventing rounding and allowing higher torque transfer. The included universal bit holder with retaining ring holds bits firmly yet allows one-handed bit changes. The compact Bit-Check case provides organized storage and quick access, with clear labeling for each bit position.
