Q: Will this adapter work with my impact driver and drill?
A: Yes! This adapter features a standard 1/4-inch hex shank that fits all impact drivers, drills, and drill/drivers with 1/4-inch hex chucks or standard keyless chucks. It's compatible with Milwaukee, DeWalt, Makita, Ryobi, and all other major power tool brands. Simply insert the hex shank into your tool's chuck and tighten securely.

Q: Can I use this adapter with regular sockets or do I need special impact sockets?
A: While this adapter works with both regular chrome sockets and impact sockets, we strongly recommend using impact-rated sockets when using this adapter with an impact driver. Impact sockets are specifically designed to handle the high torque and repetitive impacts, preventing cracking or shattering. Regular chrome sockets may fail under impact driver use and could cause injury.

Q: What's the difference between this and a cheaper adapter?
A: Milwaukee Shockwave adapters feature hardened steel construction that's specifically engineered to withstand the extreme forces generated by modern high-torque impact drivers. Cheaper adapters often use softer metals that can twist, crack, or break under heavy use. The precision machining ensures proper socket retention and reduces wobble, while the impact-rated design provides long-lasting durability that cheaper alternatives can't match.

Q: How much torque can this adapter handle?
A: While Milwaukee doesn't publish specific torque ratings for this adapter, it's designed to work with professional-grade impact drivers that can generate 1,500+ in-lbs of torque. The Shockwave construction handles the demands of automotive work, heavy equipment maintenance, and industrial applications. For best results and longest life, match your socket size to the fastener size and avoid using oversized sockets on small fasteners, which can cause excessive stress.
