Screwdriver Bit Set KWB 123244 3 pcs Torx T25 T30 T40 150 mm

The KWB Torsion bits set (3 pcs) contains three extra-long Torx bits (T25, T30, T40) with a length of 150 mm and a 1/4" (6.3 mm) shank. These bits are designed for access to deep or hard-to-reach screws and are made from TQ60 steel. A colour code on the bit heads helps to quickly identify sizes.

Advantages

The extended torsion zone at the tip absorbs peak loads by allowing controlled distortion of the bit tip, which reduces the risk of premature breakage and increases tool life. The extra-long 150 mm design provides reach into recessed screw locations, and the 1/4" E 6.3 shank ensures compatibility with standard bit holders and drivers.

Suitable for

• Reaching deep or recessed Torx screws
• Heavy-duty fastening tasks where peak loads occur
• Use with 1/4" bit holders, manual screwdrivers and impact drivers compatible with 6.3 mm shanks

Key specifications

• Bit types: Torx T25, T30, T40
• Length: 150 mm
• Material: TQ60 steel
• Shank: 1/4" (6.3 mm) E-shank
• Colour-coded heads for size identification

How to use

Insert the 1/4" shank into a compatible bit holder or driver. Select the required Torx size and engage the bit fully in the screw head to prevent cam-out. Apply steady pressure and rotate the driver at an appropriate speed; the torsion zone will absorb sudden peak loads during torque peaks. After use, store the bits in a secure holder to avoid damage.

Usage recommendations

Use these torsion bits for applications where higher torque spikes may occur. Match the Torx size to the screw head, avoid excessive side load, and replace bits showing significant wear or visible tip distortion to maintain fastening quality.
