Conjunto de bits de chave de fendas Wiha 42127

The Wiha 42127 screwdriver bit set contains five 49 mm hex (imperial) bits with a 1/4" shank. Designed by Wiha, these bits follow the company's universal TY bit concept that selects bits by screw shape only. The set is intended to provide durable, precise engagement for a variety of fastening tasks and is suitable for use with manual drivers, power tools and impact screwdrivers where compatible.

Advantages

The TY bit concept allows one bit to fit both T-shaped and Y-shaped screws, simplifying bit selection. A patented torsion zone absorbs peak loads and extends service life significantly compared to standard bits. The bits feature a fluorescent coating that makes them easy to locate, including under UV light, reducing loss. Their 1/4" shank and 49 mm length make them compatible with common bit holders and drivers.

How to use

Select the appropriate TY bit for the screw head, insert the 1/4" shank into a compatible driver or bit holder, and engage the screw head. For power or impact tools, ensure the driver and application are rated for the screw type and size. Apply steady pressure and allow the torsion zone to absorb sudden torque peaks; replace bits once wear reduces fit or performance.

Recommendations

Use the bits with appropriate drivers and within the torque limits of your tools. Inspect bits regularly for wear and clean fluorescent coating as needed to maintain visibility under UV light. Store bits in a dedicated holder to minimize loss.
