Shockwave Impact Driver Bits are engineered to be the most durable, best fitting driver bits on the market. The Wear Guard Tip delivers increased wear resistance which protects the fit over the life of the bit. The Shockzone is optimized for each tip type and length of driver bit to absorb peak torque and prevent breaking. Laser hardening at the tip creates an outer protective shield for improved wear resistance. The Custom Alloy76 has a customized steel and heat treatment per tip type to extend the life of the driver bits, providing up to 50X life vs. competitive impact driver bits. Shockwave driver bits are built to deliver extreme durability for the most demanding applications. Laser etched for easy identification. Designed for use with impact drivers and drill drivers.
