The Milwaukee SHOCKWAVE™ Locking Bit Holder has been engineered to be the strongest locking holder on the market. This auto-locking design fits all 1/4in hex bits. It has a small-profile, quick-release collar for easy one-handed bit tip change.

It has 2 magnets for maximum magnetic transfer and holding power, this also helps prevent drops. As with all SHOCKWAVE™ impact duty accessories, each bit holder features optimised SHOCKWAVE™ geometry to provide up to 30x longer life and absorb 3x more torque to prevent from breakage.
