I wanted a spare key for my Powermatic drill press. This works perfectly. I like the yellow rubber coating because it makes it easier to locate. To find the chuck key that fits your chuck, make sure you have the right number of teeth (this one has eleven) and the the same top head diameter (this one is 8mm). This is a great value and is very well made. Highly recommend.

Spare chuck keys for my hanging rotary tool because no one puts it back where it belongs
