About This Product
This drill chuck adapter is a lifesaver if you want to use standard twist drills with your SDS Plus hammer drill.
It's got a clamping range of 1.
5 to 13mm (that's 1/16 to 1/2 inch), so it covers most common drill bit sizes.

The thread mount is 1/2-inch-20 UNF, which fits a ton of drill models and brands.
The all-metal construction means it's tough and durable – no cheap plastic parts that'll crack under pressure.

The classic keyed three-jaw design lets you lock bits in quickly and securely, and it works with impact drills, rotary hammers, and other power tools.
Perfect for centering, drilling, tapping, and reaming operations.
Just screw the adapter onto your drill, pop in the bit, and you're good to go.

A couple of things to keep in mind – don't use it counterclockwise, and switch your drill to hammer mode for best results when using it that way.

Also, it works best between 500 and 3500 rpm.

Solid tool for anyone who wants to get more versatility out of their hammer drill.
