Great product, once use explained

10 years ago
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.

Yes, I recommend this product.

Hey Milwaukee, anyone home??

The mystery of the set screw on the outside of this thing was first described in this forum 5 years ago, and has been the subject of reviews ever since. Eventually, 22 days ago, a Milwaukee representative responds with "We would like the opportunity to investigate your feedback further"! Really? If the fact that people are removing a set screw that should not be removed - because THERE ARE NO INSTRUCTIONS otherwise - is not enough information, certainly the post by T_Soup 6 months ago ("How It Works, With Technical Info") should make it very clear. Please, include instructions in the package and do something to prevent the set screw for the locking pin from being easily removed. This tool is nice, but Milwaukee seems to have slid far downhill - so 3 stars.

No, I do not recommend this product.

Dissapointed

7 years ago
I have had excellent results with the smaller hole saws on the fixed arbor. Recently I bought a 1 3/8 hole saw and had to buy the larger slide arbor. This was a disaster. The hole saw screwed down within a half turn of bottoming out, and the drive pins engaged properly. But the hole saw is still wobbly on the arbor. I cut a hole in 16 gauge steel and got a very messy cut, larger than the 1 3/8 with ragged edges. The saw was obviously loose on the shaft and described a wide ragged cut rather than the clean cuts I am used to with the fixed smaller arbor that screws down tight. This looks like a poor design to me. I recall an older model with a hex nut that tightened up behind the drive pins. Do I have a defective arbor or am I doing something wrong ?? I would certainly not buy this again.

Great, until I lost the set screw.

Like many reviews, I really liked this setup, but not knowing any better I started playing with the set screw, I thought I had it all dialed back in, but after using it a couple times, and realizing the saw threads were just locking down, I checked the set screw. Sure enough, the innards (set screw, spring, ball bearing) are all gone, so now it's time to try to find replacement parts. I'm saying I would recommend it, but only if I could tell that person to be careful with the set screw.

Yes, I recommend this product.

How It Works, With Technical Info

6 years ago
OPERATION AND CONSTRUCTION A hole saw is screwed onto 5/18-18 threads on the end of the arbor. A 1/4" pilot bit in the end of the arbor guides the drill. The pilot bit depth is adjustable for different length saws and is held in position by a 1/4-28 by 3/16" long set screw. It uses a 1/8" Allen key. Expose the set screw by pulling the collar down. The saw is prevented from turning when in use by two pins on a sliding collar. The collar is locked in the up position by a spring loaded latch. You just slide the collar up and down, no tools required. You shouldn't need to touch the spring loaded latch, but if you do and the pieces fly all over the place, here's how it's constructed: a 1/8" ball bearing, a 1/8" OD spring (approximately 0.2" long), and a 8-32 by 1/8" long set screw. The set screw uses a 5/64" Allen key.

Yes, I recommend this product.

Maybe in a pinch

4 years ago
Like everyone else lost spring and bearing, stripped the hex nut in the process. It looks as if it were designed to fall apart requiring another trip to store to get the replacement arbor. The real problem is the time I loose trying to make it work. I have more to do than maintain a tool that I use infrequently. I would prefer a Festool or Makita, tool companies that seem to take pride in making tools that are high quality and thought through.

No, I do not recommend this product.

Good idea, terribly executed.

I love the idea to put pins through the blade so the threads don't jam and removal is easy. Great. But the set screw/spring/bearing thing is possibly the most boneheaded tool design in history. Obviously we all lost the parts. Obviously. Why not just a longer set screw, or if the spring compression is needed to keep things tight then design those parts as one piece so it's harder to lose. Awful.

just got it home trying to determine how it goes together with the saw part, saw the allen nut and guess what, removed it to see if it made a difference, saw a small ball bearing fly, never knew there was a spring til I came on this site.. not sure I would recommend (it at this point) this fr a DIY, there should be a few more instructions provided with it.taking it back to store tomorrow.
