Engineered for high-torque power tool applications, this 61-piece impact bit set utilizes a 1/4" hex drive and a tuned torsion zone to reduce tip stress. Each bit is manufactured with computer-controlled heat treatment to achieve a service life 120 times longer than standard bits. Furthermore, the CVM tool steel construction maintains a minimum hardness tolerance of 61 HRC +/- 1 to prevent cam-out and breakage during use.
