Sealey Impact Power Tool Bits - T40 - 25mm - 3pc

These bits are specifically designed for T40 Torx (star-shaped) fasteners.

Yes, you can use them with a standard drill/driver, but they are optimized for the high torque and impact of an impact driver. For standard drills, ensure you use a lower torque setting to avoid stripping.

Impact grade bits are made from stronger materials (like S2 steel) and often have specific designs (like torsion zones) to withstand the shock and high torque generated by impact drivers, preventing premature breakage.

Ensure the bit is fully inserted into the fastener head, apply firm downward pressure, and use the correct size bit. Using an impact driver properly also helps maintain engagement.

The bits are forged from high-quality S2 steel.

These specific bits are 25mm in length.

Yes, their impact grade, S2 steel construction, and T40 size make them suitable for demanding professional automotive repair and maintenance tasks.

Ensure you are using the correct T40 bit size for the fastener. Verify the bit is fully seated in the driver chuck and that the driver is set to an appropriate torque/impact setting. Apply firm, consistent pressure directly inline with the fastener.

Inspect the tip for rounding, chipping, or deformation. If damage is present, cease use immediately to prevent further damage to the fastener and replace the bit. Worn bits reduce efficiency and increase the risk of cam-out.

Check that the impact driver has sufficient battery power or is properly connected to a power source. Ensure the bit is securely engaged in the fastener head and that the driver's impact mechanism is functioning correctly.
