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
