Wera 851/1 PH Impaktor Phillips Screwdriver Bits

This variant is the Wera 851/4 PH Impaktor bit in PH2, 50mm, supplied in a pack of 5. The extended 50mm length provides additional reach for deeper recesses, countersunk fixings, and applications where a standard 25mm bit simply won't reach. The PH2 profile covers the vast majority of everyday Phillips screws across construction, joinery, and general trade work.

Impaktor technology ensures these longer bits remain resilient under the extreme torque and vibration of impact drivers, resisting the torsional stress that causes premature failure in conventional bits. The diamond-particle tip coating grips the screw head tenaciously, preventing cam-out and surface damage.

Colour-coded for instant identification, these bits are a practical addition to any professional impact driver kit.

Features and Benefits:
• Impaktor technology engineered for impact driver use
• Diamond-particle tip coating prevents cam-out and slipping
• Extended length for improved reach in deep or recessed fixings
• 1/4" hexagon shank — Wera connecting series 4
• Colour-coded for fast profile and size identification
• Suitable for holders as per DIN ISO 1173-F 6.3
