Wera Diamond Coated 851/1 BDC Phillip #2 Insert Bit, 1/4-Inch Drive
Wera 851/1 BDC Phillip #2 bit for 1/4" hex drive is designed to significantly extend the life of the bit. BiTorsion Diamond Coated (BDC) bits ensure safe working, especially driving screws into delicate materials or high-quality surfaces.  Diamond coated bits “bite” into the fastener ensuring a secure fit and reducing cam-out effect, extending the life of the tool. Wera BiTorsion bits have a specially tempered torsion zone that diverts impact away from drive tip reducing the risk of breakage and extending bit life. BiTorsion bit holder in conjunction with BiTorsion bits significantly extends the bit service life. German engineered. Bit dimension: 1/4” hex drive; PH2 x 1". Wera – The Best Tools For The Job!
