Customer Reviews
Rated 4 out of 5 by from Nice tool poor instructions Poor explanation. I spent time trying to unscrew the set screw until I found out that the set screw must be left alone. I am glad I found out online before I bought an allen wrench to remove the set screw and ruin the tool. It is a great tool once I learned how to use it.

Rated 4 out of 5 by from Great product, once use explained I agree with other commenters, it should not be necessary to remove the smaller set screw. This screw holds small ball bearing and spring that make the quick-disconnect feature work. Because of inadequate instructions with point-of-sale packaging, I too, took out the smaller set screw (larger set screw holds twist drill) only to have the ball bearing fall to floor and I never did see a spring. I had to return the original item to my retailer. I wonder how many get returned before Milwaukee Tool will agree to improve packaging instructions for what is otherwise a great product.

Rated 5 out of 5 by from Easy to Use and Strong This was included in the Milwaukee 14 piece bi-metal hole saw set. Simply pull back the collar, thread on the hole saw and push the collar back. The threads are very good quality and clean, so the hole saw spins on effortlessly. Best of all, NO TOOLS REQUIRED! There is no need to remove the allen screw, it just destroys the arbor.

Rated 3 out of 5 by from Lost parts My only complaint would be that the set screw design for holding the arbor in place is not intuitive. One of my workers lost the ball bearing and spring the first time useing it. I'll purchase a new arbor and give specific instructions to workers who might try to use it in the future.

Rated 4 out of 5 by from Use I know it's not that intuitive, but to use this you need to pull the collar to expose the shank where your hole blade will fit. Once you screw it on, then push the collar back to lock the blade in place. Took all of 1 minute to figure this out and there's no need to remove the allen screw. Good luck folks and hope this helps.

Rated 1 out of 5 by from Can't get it to work I removed the Allen screw and can't get the bit and the arbor back together again. So I can't use it. Very frustrated and disappointed.

Rated 4 out of 5 by from So glad I read the reviews! I bought the 4" hole saw for sutting light fixture boxes and the quick change arbor to fit it. It says pull to release on the package, but fails to mention you must first loosen the allen screw in the tool free design statement. Didn;t feel so dumb after reading the other comments in the reviews.

Rated 3 out of 5 by from Don't pull the arbor apart!! Do not dis assemble the arbor right out of the container. I have other hole saws with a common arbot that screws into place and relies on flats on the threaded shaft to prevent rotation of the saw blade. The problem with this design is that it uses a detent designed with a ball bearing, spring and small allen head screw that forces the ball bearig into a groove on the arbor shaft. If you pull the arbor apart like I did, the ball bearing and spring fall out. Fortunately, I found the ball bearing right away. Unfortunately, it took me 15 mintues of chinese puzzle playing and looking on line for documentation (which I couldn't find on the Milwaukie web site) before I determined that there must be a spring as part of the detent design. Luckily I found the spring and assembled it with some lock-tite blue to hold the screw in place.Now the arbor works well, but the saw blade still has a little play in the rotation because you have the pins on the sliding collar have to align with the holes in the base of the saw blade. I hope this saves a few headaches... Milwaukie, either change the desigh or put some directions on the cotainer, a "do not disassemble" or other thing that prevents us idiots from assuming this kind of mistake.
