Wera 855/4 IMP DC PoziDriv PZ1 Bit de impacto com revestimento de diamante, sextavado 1/4 polegadas, 50 mm 05073961001

Cam-out and premature wear are the two biggest frustrations when driving PoziDriv screws under high torque. The Wera 855/4 IMP DC bit eliminates both: its diamond-coated tip bites into the screw recess, while the torsion zone absorbs impact peaks so the bit lasts far longer in impact drivers. This is the PZ 1 size, 50 mm long, on a standard 1/4" hex shank.

Who is it for

Professional tradespeople, cabinet makers, and serious DIYers who use impact drivers and demand bits that hold up. If you regularly drive PoziDriv screws in hard materials or high volumes, this bit will outlast conventional bits many times over.

Tips

For best results, use this bit in an impact driver rather than a standard drill/driver. The torsion zone is designed to flex under impact, so it may not perform optimally in a non-impact tool. Keep the bit clean and dry; the diamond coating is extremely hard but can be damaged by harsh chemicals. Store in a dry place to prevent corrosion of the steel body.
