Wiha Bits are engineered to DIN ISO 1173 and DIN ISO 3658, delivering torsion zones that absorb peak torques up to 40 Nm without tip deformation - measurably reducing cam-out on hardened fasteners. The precision-ground S2 steel tips maintain a dimensional tolerance of <0.05 mm across the full profile, covering PH, PZ, TX, TORX PLUS, HEX, SL, SQ, and TORQ-SET geometries from PH0 to PH4 and T1 to T100. Shaft diameters follow the 1/4 " C6.3, E6.3, and 1/2 " drive standards, with impact-grade variants rated to 450 Nm impact impulse for use with Wiha ImpactDrive and compatible pneumatic or cordless tools.

As an authorised Wiha distribution partner, esd.equipment stocks 495 bit references - individual bits, bit sets, bit holders, and finder magazines - all conforming to DIN ISO 2380, DIN 5260, and the applicable ASME B107 cross-references. Every variant is available ex-stock with same-day dispatch, backed by full Wiha manufacturer traceability for ISO 9001 and IATF 16949 procurement documentation.
