Makita® Impact XPS® is new innovation in fastening with insert bits and fastening accessories built for the demands of the professional contractor. The ImpactXPS #1 Phillips 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 #1 Phillips 1” Insert Bits are ideal for the most demanding jobs including deck building, framing, installing plywood subfloor, and more.
