Screwdriver bit set Bosch 3 pcs extra hard, Hex 3 mm, 49 mm length, 1/4 inch shank

The Bosch Screwdriver bit set (3 pcs) extra hard with Hex 3 mm tips and 49 mm length is a compact set of durable bits designed for precision fastening and repair tasks. Each bit has a 1/4" shank compatible with standard bit holders and quick-change chucks, supplied in a blister pack for convenient storage and transport. The extra hard material and tapered torsion zone make these bits suitable for repeated use where wear resistance and reliable torque transmission are required.

Advantages

Extra hard construction increases wear resistance and extends service life. The tapered torsion zone absorbs torque peaks to reduce the risk of breakage and bit deformation. Standard 1/4" shank ensures compatibility with most bit holders and quick-change systems. Compact three-piece set provides the common Hex 3 mm size for precision fastening applications.

How to use

Select the Hex 3 mm bit from the set and insert the 1/4" shank into a compatible bit holder or quick-change chuck. Ensure the bit is seated securely before applying torque. Use steady, controlled force and allow the tapered torsion zone to absorb sudden torque peaks. After use, return bits to the blister pack to keep them protected and organised.

Recommendations

Use the extra hard bits for jobs requiring durability and repeatability; avoid excessive lateral force and inspect bits regularly for wear to maintain secure screw engagement.
