Order this Makita 3 in. IMPACT XPS T25 Torx Power Bit for delivery. Precision machined tips, pulse torsion rings, an optimized torsion zone and unique steel, combine to deliver improved overall performance and bit life. Lasts up to 90X longer than standard impact bits. Precision machined tips provide a superior full contact fit for improved holding power and longer life. Pulse torsion rings help to disperse impact energy through the torsion zone and off of the bit tip. Optimized torsion zone geometry facilitates an ideal transfer of impact energy for improved bit life. Unique steel composition is masterfully engineered for extended life compared to S2 and S6 alloys. Uniquely calibrated heat treating process for added durability. Matte nickel surface for best in class corrosion resistance. 12-sided bit collar for use with the ImpactXPS mag boost sleeve for added holding power. Engineered to withstand the extreme power of high-torque impact drivers and to last longer than standard impact bits.
