Not as described!
Used only once, never again! Product locks but as soon as impacting starts it WILL release whatever you have in the "lock"!!! Lost a fairly expensive drill bit going into a hollow space! Now I've contacted Milwaukee about it to have no response in return! Go with another brand, whatever you do don't get this overpriced tool!

      I used this to extend the reach of a 1 1/8 inch ship auger bit to install 3/4 inch rigid conduit in a garage. The ship auger bit was held very tightly and had minimal wobble, allowing me to keep the holes lined up to easily install the conduit. The QUIK-LOK worked great to keep the auger bit where it is supposed to be and easy to remove when done. Great quality tool as I expect from Milwaukee.

        I can only give this a 4-star rating as I haven't used it yet. I have owned the 6" & 18" and I give those 5-star ratings. Easily insert & remove any compatible tool and have used extensions together for more length. Can now make a hole up to 1.25-5in(dia.) x 3in-3ft deep(long). Caution, they get heavy the more you add.
