HARFINGTON 3pcs TT27 Security Torx Head Screwdriver Bit 4.33" (110mm) Long 1/4" Hex Shank Magnetic Tamper Proof 6 Point Star Screw Driver Drill Bits S2 Steel Hole Tip Industrial Power Tools

Torx head with hole can be in close contact with the screw, making it more stable and less likely to slip during disassembly and assembly. The TT value indicates the size of the torx head. The larger the value, the larger the head, and the smaller the value, the smaller the head.Industrial grade security torx drill bit is made from specially heat-treated S2 steel for superior strength, hardness and durability, with a sandblasted surface for a textured effect for enhanced grip and corrosion resistance.The tamper proof 6 point star head of the screw driver is magnetized for easy use. Torx head driver with strong magnetism can stably absorb the screw vertically or obliquely, making it easy to fix the screw, especially in a small space. Precision CNC machined torx head, precise appearance, reduces head wear during high-intensity tightening operations.Special torque buffer design, when the vibration generated during operation is absorbed by this part, the torque transmission is increased, achieving the effect of protecting the screwdriver head and extending the service life.Magnetic torx drill bit wrench is specifically designed for driving screws into wood, metal, and other materials effortlessly. Can accurately tighten screws without damaging screws and security bit. 1/4" drive hex shank bits can be used with electric screwdrivers, manual screwdrivers, electric drills, etc. for electricians, mechanical repair work, and furniture installation.Make sure the torx bit is firmly inserted into the power tool chuck before operation. Avoid using excessive force when tightening the screws to prevent the bit from being damaged or slipping out. Store the screwdriver bit in a dry place to prevent rust and maintain its performance.
