KWB 121620 -ruuvauskärki, 3 kpl, teräs, T20, 25 mm

The KWB 121620 screwdriver bit set contains three steel T20 bits, each 25 mm long with a 1/4 inch (25.4 / 4 mm) shank. Designed for use with manual and powered screwdrivers that accept 1/4 inch hex bits, this compact set provides a standard Torx T20 tip for general fastening tasks. The bits are intended to deliver a secure fit in T20 fasteners while fitting common bit holders and quick-change chucks.

Advantages

The steel construction provides wear resistance for repeated use and maintains tip geometry for reliable engagement with T20 screw heads. The 25 mm length balances reach and control, making the bits suitable for confined spaces while still offering sufficient clearance for common screw depths. The 1/4 inch shank ensures compatibility with most bit holders, impact drivers, and cordless screwdrivers that accept hex bits.

How to use

Select a T20 bit from the set and insert the 1/4 inch hex shank into the bit holder or chuck of your screwdriver or driver. Ensure the bit is fully seated and locked if the holder has a retention mechanism. Align the Torx tip with the screw head, apply steady axial pressure, and operate the driver at an appropriate speed and torque for the material and fastener size. Withdraw the bit straight from the holder after use and inspect the tip for wear before storing.

Recommendations

Use the bits with compatible 1/4 inch bit holders and set torque settings on powered drivers to avoid cam-out or tip damage. Store the bits in a dry place and replace any bit that shows rounding or significant wear to maintain safe and effective fastening performance.
