Tackle demanding fastening jobs with complete control using the Wera 851/1 imp DC sb SiS Impaktor Phillips bit. Engineered with Impaktor technology, it reliably withstands extreme torque peaks from cordless impact drivers, preventing premature breakage and extending service life. The diamond-particle coating bites firmly into the screw recess to reduce cam-out and slippage, significantly lowering the contact pressure required during heavy-duty fastening in timber or drywall framing. Featuring a standard 1/4" hexagon drive, a 25 mm length, and distinct PH2 profile identification, this bit delivers the strength and precision you need on every project.
High quality bits for Phillips screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Particularly suitable for use with customary impact drivers. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
