Broca de atornillar Bosch extra dura

The Bosch Screwdriver Bit Extra Hard set contains 25 Torx T20 bits, each 25 mm long with a 1/4" hexagonal shank. Designed for durability and precision, the extra hard steel and a tapered torsion zone help the bits withstand high torque and perform reliably across a range of fastening tasks.

Advantages

The extra hard material increases wear resistance and extends service life. A tapered torsion zone absorbs torque peaks to reduce breakage. The uniform length and 1/4" hex shank ensure compatibility with standard bit holders and impact drivers. The bits are supplied in a compact box for organised storage and easy transport.

How to use

Select a T20 bit from the box and insert it into the 1/4" bit holder or driver chuck until it seats securely. Use appropriate torque settings on the driver to match the workpiece and fastener size. Allow the tapered torsion zone to absorb sudden torque spikes; replace bits if signs of wear or rounding appear.

Recommendations

Use with compatible 1/4" bit holders or impact drivers and set torque to the level appropriate for the fastener and material. Store bits in the supplied box and inspect tips regularly to maintain fastening precision.
