The black phosphate coating is corrosion-resistant and reduces friction, making operation smoother and the screwdriver bit life longer. The slotted head drill bit adopts magnetic design, which can absorb screws vertically or tilted, making it easy to remove and install screws in a small space. The special torque buffer design can absorb the vibration generated during operation, increase torque transmission, reduce head wear and extend service life. The impact slotted driver bit is precision machined for a consistent fit, and features a single slot design for use with Phillips or single slot screw constructions, provides higher torque, and is designed and constructed to withstand impact drills.
