HARFINGTON 2pcs SL4 Slotted Impact Screwdriver Bits 4mm Slotted Tip 1/4" Hex Shank 50mm (2") Long Magnetic Flat Head Phosphated S2 Steel Screw Driver Drill Bits Electric Power Tool

Magnetic flat head screwdriver bits are made of heat-treated S2 steel with a hardness of up to HRC60-61, providing excellent strength, hardness and durability. 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.Slotted flat head drill bits are suitable for furniture assembly, mechanical equipment installation, auto repair, home DIY projects, homemade furniture, construction, carpentry construction, etc. 1/4" drive hex shank is widely used in impact drills, electric screwdrivers, manual screwdrivers, power drills, etc.. Please check whether it is firmly installed on the power tool before use. Avoid using excessive force when tightening the screws to prevent the bit from being damaged or slipping out.
