Shockwave Matrix Carbide impact driver bits have new-to-world innovation that solves the frustration of driver bit tips wearing out prematurely. The impact driver bits combine optimized Shockzone technology with new proprietary Matrix Carbide Steel to give this driver bit the ability to absorb the peak torques of impacts while also providing extreme wear resistance. Matrix Carbide Steel is a proprietary steel that contains evenly distributed carbide for extreme wear resistance. Nickel plated for best corrosion prevention. Bits feature a precise fit custom machined tip to prevent stripping and reduce wobble. This advancement in impact driver bit technology is backed with a Lifetime Tip Warranty. Designed for use with impact drivers and drill drivers.
