Product Overview
The Wera 851/4 BDC bit (05059530001) is a Phillips PH1 bit with a blade length of 50 mm. The product is a spare part/accessory bit designed for screws with a Phillips head and is mounted in holder systems with a 1/4" hexagon drive. The Wera 851/4 BDC bit is specified by the manufacturer to reduce wear and improve grip in screw heads through two visible features: a BiTorsion zone and a diamond-coated tip.Design and Functionality
The bit has a BiTorsion zone which, according to the manufacturer's documentation, absorbs peak loads, thereby reducing the risk of premature breakage and increasing the bit's lifespan. The diamond-coated tip provides increased friction against the screw head, which reduces cam-out and ensures a more secure grip in the screw.- Profile: Phillips PH1
- Blade length: 50 mm
- Drive: 1/4" hexagon (Wera connecting series 4) — suitable for holders according to DIN ISO 1173-F 6.3
Documentation
For technical details and manufacturer information, please refer to the Wera datasheet: See datasheet from manufacturer.Typical Applications
According to the manufacturer's information, this bit is designed for use in screwdriving tasks with Phillips screws, especially in power tool applications where peak loads may occur. The BiTorsion system and diamond coating reduce the risk of slipping (cam-out) and protect the screw head, which is relevant in work situations where precise fit and low slip are desired.Specifications
