Makita's new XPS range with pulse torsion zone technology, is the next generation of premium fastening accessories for trade use, engineered to withstand the high torque provided by current impact drivers as well as for use in drill/drivers and screwdrivers. The Impact XPS series is expertly engineered to the highest quality for exceptional product life. Three unique features combined together to deliver 100x longer performance life Exact Fitment: Precision machined bit tips engineered to fit screws with minimal variance, thereby minimizing wear on the bit and screw. This helps prevent premature tip wear and the screw head from stripping. Pulse Torsion Ring and Zone: Pulse torsion rings are specially engineered to disperse impact energy through the torsion zone and direct to the bit tip. The torsion zone has been optimized to flex under load to transfer impact energy for improved bit life. The length combined with diameter of the bit, is a special formula to create an optimized torsion zone. This engineering works together for longer performance life. Unique Steel Blend: The unique carbon alloy steel composition of the XPS range is engineered for increased durability of the bits for longer life as well as minimizing premature damage of driver tip Insert & Power Bits: Impact XPS Insert & Power Bits features exact fitment, pulse torsion rings / zone and unique steel blend for up to 100 times longer performance life than standard bits Insert Bit Holders: Impact XPS Magnetic Insert Bit Holders are engineered to allow the torsion section of the bit holder to flex under load taking pressure off the bit tip for increased durability in high torque applications
