Our 14-in-1 multi-bit screwdriver with SHOCKWAVE Impact Duty™ driver bits is the most versatile multi-bit screwdriver. This multi-bit driver features easy-access in-handle storage which keeps bits organized, allowing you to quickly change bit sizes and types.

The wear guard tip delivers increased wear resistance which protects the impact bit's fit over the life of the bit. The shock zone is optimized to absorb peak torque and prevent breaking. The driver bits are made from custom alloy76 steel and a proprietary heat treatment process to extend bit life, providing up to 50X life versus other impact driver bits on the market. The removable SHOCKWAVE Impact Duty™ magnetic bit holder has a 1/4 in hex shank, making it impact ready for maximum jobsite versatility. The screwdriver handle is backed by a limited lifetime warranty.
