Wera 851/1 PH Impaktor Phillips Screwdriver Bits

This variant is the Wera 851/1 PH Impaktor bit in PH3, 25mm, supplied in a pack of 10. The PH3 profile is designed for larger Phillips screws, typically found in heavy-duty structural applications, large carcass work, and industrial assembly. The 25mm length provides a compact, controlled option for situations where access is limited.

Wera's Impaktor technology makes these bits specifically suited to impact drivers, handling the intense shock loads and high torque that standard bits simply cannot endure. The rough diamond-particle coating on the tip grips the screw head with real bite, dramatically reducing cam-out and ensuring clean, consistent drives every time.

Colour-coded in line with Wera's Take It Easy system for quick identification by profile and size.

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