Drill Bit Set Wiha 42125 5 pcs

The Wiha 42125 drill bit set contains five high-quality screwdriver-style drill bits each 49 mm in length with a hex shank designed for secure insertion into bit holders and quick-change chucks. Manufactured by Wiha, these bits are intended for a range of drilling and fastening tasks where compact bit length and a reliable fit matter. The set is appropriate for users who need consistent performance in both professional and home workshop environments.

Advantages

These drill bits combine short 49 mm length with a hex shank to provide good control in tight spaces and compatibility with most magnetic bit holders and impact drivers. The precision machining of the tips supports accurate engagement with screw heads and reduces cam-out, while the robust material and heat treatment increase wear resistance and longevity under repeated use.

How to use

Select the appropriate bit from the set and insert the hex shank into a compatible bit holder, quick-change chuck or cordless driver. Ensure the bit is seated fully and locked before applying torque. For controlled results in tight spaces use moderate speed and steady pressure; back the bit out periodically when drilling to clear debris and reduce heat build-up. Replace bits when tip wear affects engagement or when bending or chipping is visible.

Recommendations

For optimal life and performance, match the bit type and size to the fastener and application, avoid excessive side loads, and store bits dry to prevent corrosion. Use appropriate personal protective equipment when drilling or driving fasteners.
