7/16 in. Quick Change Large Hole Saw Arbor No Wobble W/ W/ Pilot Drill Bit

[This review was collected as part of a promotion.] I can’t say enough praise for my Milwaukee Large Thread Quick Change Arbor. It quickly installs cutting different sized accessories from 1 1/4” to 6 7/8”. I really think it’s awesome because no wrench is necessary to tighten the attachments. Would highly recommend this as a great addition to anyone’s tool set.

[This review was collected as part of a promotion.] This quick changer arbor is excellent. I've purchased many different brands and none compared to this one. This arbor holds the Hole dozer in place and extremely solid. There are no worries of this Arbor breaking or wearing out any time soon. The bit is extremely sharp and drills through the wood and Corian like a breeze. The bit is solid and I also have no worries of it breaking under normal use. I would definitely recommend this arbor to anyone in any field. I love it and threw out the other one's I owned.

Makes the machin impact drill wanna dance lol so smooth

Can't use the hole saw without it. Once I figured out how to secure it to the round blade, all went well.

First off, Milwaukee needs to put some instructions on the packaging, see below (and pics) on how to use this hole saw. I bought the 4 1/8" hole saw to bore holes for dryer, bathroom & kitchen 4" exhaust vents. I thought the 4" would work, but the plastic vent shaft is actually a hair over 4" so a 4" hole saw is really too small. It's actually a tight fit even with the 4 1/8” hole saw. If you have a job that will require you to attach the venting hose as well as a hose clamp that you need to put on first, and then install it, like for a soffit, then you'll need a larger hole saw. I was able to do the 3 holes I needed with the 4 1/8", but I should mention that I had access to the soffit from the inside because the ceiling drywall in my new addition wasn't up yet. In the older part of my house I wanted to add a soffit vent to a bathroom, but ended up having to go 10' out to the side eve because the soffits where not accessible to tighten the hose clamp. When drilling vinyl siding you'll have to move the inner drill bit out to about 1" past the outer hole saw to keep the saw from wondering. At first I couldn't find the set screw as my older model had it closer to the end, then I realized that it's behind the tightening nut, so loosen that all the way first, then push the 2 pin collar towards the tip to access Allen screw. It takes an 1/8" (or 3mm in a pinch) Allen wrench. I found the large 1 1/8" nut really only needs to be tightened by hand as the pins really drive the saw & there is a rubber O ring between the two parts to keep enough friction on the collar. If you will be using this every day & not changing the size of the saw, then go ahead and wrench it down, but I'm constantly using different sizes and rather not have to carry a large 1 1/8" wrench or adjustable wrench around. So thank you Milwaukee for adding the rubber "O" ring. The hole saw did a great job of quickly digging right thru double thickness 3/4" 60 year old plywood which was VERY hard. The plug that was left in the saw was easy to remove with a flat head screwdriver as the access holes around the side of the saw are well placed. There are also two 5/16" holes at the back of the saw if you have a really stubborn plug & need to use a punch, dowel, bolt, head of a nail or small blade screwdriver to get it out. This Arbor can chuck in a regular 1/2" drill or Milwaukee's proprietary drills & extensions. (which are great BTW with their lock) If you found this review helpful please click on the thumbs up button, thanks! MikeTheReviewer Pics The 4 1/8" hole saw is just a hair larger than the plastic soffit vent, a 4" would be too small Attached hole saw for a 1/2" drill. Set the depth of the 1/4" inner pilot drill using an 1/8" Allen wrench (3mm will work in a pinch) Screw the inner thread into the back of the hole saw about 2 turns Seat the 2 pins on the collar into the larger outer hole saw Final step hand tighten nut onto the collar, or use an adjustable or 1 1/8" wrench. Use a screwdriver in a side hole of the saw to tighten against.

solid, just a run of the mill arbor but it's fine
