Wera ดอกไขควง 851/1 TZ (Torsion Zone), Phillips Bit PH1/PH2/PH3 x 25mm

Wera ดอกไขควง 851/1 TZ (Torsion Zone), Phillips Bit PH1/PH2/PH3 x 25mm "TZ" TZ bits are hard bits with torsion zone. Torsion bits absorb the damaging peak torque loads in the torsion zone. This prevents premature wear and enhances the service life of the bits. Premium bits for Phillips screws. Torque peaks are cushioned by the torsion shape. Premature wear is avoided and the service life of the bit is increased. Tough, for universal use. 1/4" hexagonal, suitable for holding tools as per DIN ISO 1173-D 6.3.
