Makita® Impact XPS® is new innovation in fastening with insert bits and fastening accessories built for the demands of the professional contractor. The ImpactXPS T40 Torx® 1" Insert Bits are designed exclusively for use with high-torque impact drivers, and are engineered to last up to 90-times longer than standard insert bits. High-strength steel delivers longer bit life, and the precision-fit tip is engineered to prevent "cam-out" and stripping. The torsion section of the bit flexes under load to take pressure off of the bit tip for increased durability. The high-quality steel construction is engineered for increased durability and features a matte nickel surface for best in class corrosion resistance. ImpactXPS T40 Torx® 1" Insert Bits are ideal for the most demanding jobs including deck building, framing, installing plywood subfloor, and more.
