Increases your efficiency: The specialist with a 120 times longer lifespan thanks to the optimized bit for Y-shaped screws. Reduces your costs: The bit is easily and quickly identifiable due to its yellow color marking, even in dark environments with UV light. Application: Suitable for fastening Y-shaped screws. Also compatible with impact and power screwdrivers. Until now, there has been a lack of clarity when purchasing bits regarding which bits are suitable for which applications. Wiha eliminates the complexity between the machine used, the screw case, and the wide variety of different bits. Thanks to Wiha's revolutionary bit concept, only the shape of the screw determines the selection of the right bit. Thus, the Y-bit is ideal for fastening Y-shaped screws with an angle other than 90 degrees between the thread and the screw head. With the patented extended torsion zone, the bit is also suitable for impact and power screwdrivers and has a lifespan 120 times longer compared to standard Wiha bits. Additionally, the colored bits are quickly and easily identifiable and can also be found in the dark with UV light thanks to the color coating. This reduces the number of lost bits and saves costs on replacements. DIN 3126, ISO 1173, Form C6.3. Contents: 25x Y-bit 25 mm TX 1/4 T20.
