This chuck is easy to tighten and provides an audible and tactile indication that it is tightened around the drill bit! Seems to be built sturdily and will stand up to heavy use.

Excellent chuck. Very strong and built with high quality materials. Very strong jaws. Has a ratcheting clutch like action and sound to it when hand tightening the chuck. Easy to loosen as well. Never comes loose when you are using it. Stays tight on your bit during all actions. When I got this unit, I took off the SDS adapter shaft and put it on a regular keyed chuck. I've heard that using a keyed chuck with a hammer drill, is better overall, rather than using a keyless chuck with a hammerdrill. I'm sure that it would have worked just fine with a hammerdrill though. So I put just the keyless chuck on my regular 1/2" drill, and I used the SDS adapter shaft on a keyed chuck for use with my hammerdrill. Easy to mount this chuck, and easy to use. In my opinion, this is the best keyless chuck I have ever used, and I have used many many others of different brands and sizes. Can't go wrong with the quality and design of this chuck, and having the SDS adapter shaft is a great tool to have on hand as well.

Worked great with my Bosch Bull Dog Hammer Drill.

This is just what I needed to be able to use my smooth shank drill bits in my SDS Plus drill. This adapter is very handy to keep around the workshop. This tool is not easily found in local hardware and tool stores. Better to buy it here and have it on hand when you need it instead of going out to hunt it down when you need it.

This is probably the best quality SDS Plus keyless chuck on Amazon. That being said it does the job for me but I noticed some runnout at the end of my drill bit when I ran my cordless hammer drill. It has never effected my work because I wouldn't be doing precision work with a cordless drill anyway. Also, as noted in other reviews, when the chuck is in the drill, it has the ability to move about a quarter inch axially in either direction. This does not effect any or my drilling operations because you will always be pressing into the workpiece and so you really don't notice it when drilling.Pros:-overall quality-keyless design-decent priceCons:-the chuck has some runnout to it. not intended for precise applications.-it can oscilate back and forth in the hammer drill (probably not an issue to most people)

I feel like this is almost a necessity to have with the hammer drill. My ryobi drill burnt out and having this attachment has saved me on multiple occasions since I haven’t gotten a chance to grab a new drill yet.

Did exactly what it said, nothing more nothing less. Works well, grips tighter than my old keyed chick and feels like it will last forever. You get what you pay for
