Bosch Heavy Duty No. 1 Square Drive Impact Screwdriver Bit, 1 Piece, 3-1/2" SQ1

Bosch Impact Tough impact driver bits have been improved to offer 10 times the lifespan of ordinary impact bits. Thanks to an extended torsion zone, precision engineering, and heat-treated manufacturing processes, these bits deliver powerful torque and high strength, resulting in extended use and reduced wear. These impact-resistant bits comprise a range of screwdriver bits, double-ended bits, socket screwdrivers, sleeves, and bit holders suitable for a new generation of high-torque impact drivers. These bits also feature high-visibility sleeves for greater ease of use.
