BEAT OUT 20 OTHER MANDRELS WE USED DRILLING 2000 HOLES

Reviewed in the United States on March 12, 2018

Verified Purchase

IM A COMMERCIAL PLUMBER, WE HAVE TO DRILL A LOT OF LARGE HOLES, ABOUT 2000 HOLES ON ONE JOB, AND IVE TRIED EVERY ARBOR SOLD HERE IN THE USA, THIS ONE IS SO FAR THE BEST OF ALL. THE SCREW THAT HOLDS THE PILOT BIT IN, IS A LARGER HEX THAN THE REST, BUT ALSO HAS A LARGE SLOT THROUGH IT, WHICH MAKES IT EVEN EASIER TO CHANGE ON THE FLY. THE HEX SCREWS ON ALL OTHER QUICK CHANGE MANDRELS, STRIPPED OUT AFTER ONE USE, THIS ONE HAS OUT LIVED 20 OTHER MANDRELS.WE USED THIS ON 1.5" UP TO 5" SUPER HOG DRILL BITS

Good arbor. Fits hole saws from multiple manufacturers.

Reviewed in the United States on May 2, 2017

Verified Purchase

This DeWalt arbor worked great. I particularly like the way the cap is shaped. It's easy to retract and hold while spinning a hole saw on or off the arbor.

I happened to have three hole saws that were all close to 4", and none were DeWalt. See pic. Everything fit perfectly. The Irwin, Milwaukee, and Lenox hole saws all installed easily on the DeWalt arbor. Interchangeable. Maybe you knew that already but here's the pic to prove it.

This arbor fit nicely in the 3/8" chuck on my Hitachi drill. That said, a 4" hole saw in wood is a torque-hungry monster. A 3/8" drill may be able to handle a couple holes, with care. Cutting holes in drywall for recessed lights, etc., could be done with a drill that size. If the project is bigger than that, a 1/2" drill is the way to go, for safety, neatness, and wear and tear on the drill.

Serviceable Arbor...But can't be used with 3/8" drill chuck

Reviewed in the United States on January 26, 2018

Verified Purchase

The problem with this arbor is that it can only be used with a 1/2" drill. Its 7/16" hex shaft is too big for a 3/8" drill. This is a big disadvantage for drilling 4" holes in ceilings for recessed lighting cans where a 3/8" drill is more than adequate. In looking at Dewalt's 3/8" arbor, it claims to be only usable with small hole saws and doesn't describe the thread size it uses for the hole saw engagement. Also, the photo used on the Amazon site for the Dewalt 3/8" hole saw arbor is actually the picture for Dewalt's 7/16" arbor. Thus there is no way to reliably order a Dewalt arbor for a 3/8" drill to fit a hole saw with a 5/8"-18 engagement thread. I gave up and ordered a Milwaukee 49-56-7250 Hole Saw Large Arbor 3/8" Q/C, Ergo Grip.

DEWALT DW1803 Heavy Duty 7/16-Inch Shank Quick Change Mandrel-does it work?

Reviewed in the United States on July 18, 2019

Verified Purchase

I love how easy it is to mate this to a hole saw bit. You tighten it down until the two locking pins engage. No more using a wrench and a back up wrench to secure mandrel to hole saw. This allows for easy removal pull back on quick release(think air hose connection) then unscrew it. The lockup is very secure will not spin the mandrel on the hole saw bit at all. I will only buy hole saw bits that support the dual pin lock going forward. I usually try to include any negatives but so far there has not been any.

First Dewalt product that utterly failed me.

Reviewed in the United States on July 19, 2019

Verified Purchase

This the first Dewalt product that utterly failed me. Just using it to drill grommet holes into a desk, the inner drill bit bent almost immediately. I am older, use a battery powered drill, have skinny arms, and basically do not test the strength of most heavy duty items by my own strength. I tried to beat the drill bit back into shape on an anvil but we all know that's not going to work because it has to be perfectly straight. Perhaps I get a defective one but the bit did not live up to its heavy duty billing in my case. As a result the outer hole saw wobbled and scratched the heck out of my desk. Very disappointing.

Solid and does the job

Reviewed in the United States on December 26, 2016

Verified Purchase

Used it with hole saws ranging from 2" to 5.75". Mostly, I want to address the 1-star reviews—those who are breaking the pilot bit are doing so because they're not pre-drilling a smaller pilot hole first. Second, those who are breaking the 2 pins are most likely using an impact drill or hammer drill; I've learned that lesson. My point is that many users are blaming the product for their misuse.

Quick - As Advertised!

Reviewed in the United States on January 12, 2016

Verified Purchase

I've only ever purchased cheap hole saws and shanks from my local discount tool store. I've had hit and miss luck with those. Usually they end up wearing loose and the hole saw begins to wobble. When purchasing this, I had a hard time believing you could "quickly" swap hole saws with this thing and that they would still be held on tightly. Let me just say, this thing works amazingly well.

It attaches with threads that screw into the back of the hole saw blade. Once you get about 1/4" in, you pull the silver colored part away from the the back of the hole saw blade and screw another 1/4" or so. When you release the silver part, it releases 2 pins that will line up with the hole saw blade to lock it into place. Quick, easy, no tools required and it is SOLID. I am very happy with this product and would not hesitate to purchase it again.

Finally, a quality arbor with no wobble

Reviewed in the United States on September 13, 2020

Verified Purchase

For the last several years I've been using two different types of quick release mandrels from another big name, neither of which would create a tight connection to their own hole saws or anyone else's. On every saw, the mandrel would bottom out before it got to the next set of holes, so I had to back up a quarter turn or so to seat the pins. Wobble, wobble, wobble by design. I ordered this one based on the reviews, and I'm so glad I did. It's an all around better mouse trap. The others are in the trash.

Complete crap.

Reviewed in Canada on October 25, 2020

After first time use, the bit started falling out from the center. Second time using it (to drill holes for pot lights, both times, nothing crazy) it started sinking through the mandrel so that it was not even as deep as the hole saw. Completely useless garbage that I will never buy again!

Great DeWalt product

Reviewed in Canada on March 3, 2020

Verified Purchase

Someone’s review stated that this mandrel doesn’t fit a 3/8” chuck. It fits my 3/8” DeWalt drill’s chuck without any issue at all, and apparently fits everyone else’e 3/8” chuck as well. Mandrel’s quick release works beautifully.

Bought it by accident but kept it anyway

Reviewed in Canada on November 20, 2018

Verified Purchase

Needed a mandrel to mount my hole saw and got this. Unfortunately my hand drill only took 3/8" shanks and this one is a 7/16" one. Guess I didnt read carefully the specs. But I decided to keep it rather than return it. It'll be useful down the road.

Mandrel performed as well as I could hope for.

Reviewed in Canada on January 25, 2019

Verified Purchase

Although, I used it on a relatively small hole - 2 inch - the mandrel worked great and there was no problem with the hole saw tightening up - it was removed without difficulty - I expect that it will work equally well when I use it on some 4 inch holes in the future.
