My package has no allen wrench with it. But I see others say they have wrench inside the package....

It should come with an allen wrench. you need it to change the inner drill bit. It would be a PIA to have to run out to get one on the job. Packaging error is my guess.

is this something an electrician would use?

Excellent for carpenters, plumbers and electricians.

Can it be used to cut acrylic?

Yes. Just as any other plastic type material be sure to cut in reverse for a cleaner cut. Then when half way through stop and then cut from the back side for the cleanest cuts.

Considering using the smaller dozer bit to bore an opening through an electrical box recessed in drywall and nailed to a stud. Reasonable/fire risk?

I would definitely be sure all power is off to the box and have an appropriate fire extinguisher on hand. Also do you know what's behind the box. As long as you follow proper safety rules you should be ok. Also make sure you check local codes. You don't want to do anything that's illegal.

Milwaukee in name only
I own this kit. Basically, the only quality here is the arbors, and maybe the hard case. The hole saws themselves are poorly made. They are seamed together, and the tooth that aligns with the welded seam sticks out further than the other teeth, thus increasing the hole diameter. If accuracy is important to you, these hole saws won't work for you at any price. I only used one bit, and noticed the unusual wear, so I asked Milwaukee for a replacement. They did send a replacement (eventually). I have since inspected the other bits and noticed that the seam problem was common with most of them. I've used several sizes now, and I can honestly say that they don't cut any faster than the HF specials I've used for years. Based on every positive thing I've ever heard or read about Milwaukee tools, I doubt they manufactured these hole saws themselves.

missing 2 pilot bits
In the description it is suppose to have 5 pilot bits but there is only 3 in the box. The carboard covering the case describes it as having 3 pilot bits but than I don't see anyway to count the kit as 21. Can't find this in the store so I'm very disappointed by the inconsistancy. Tools look really good though otherwise.

My yes buy is hinged on the fact you need an organised selecton of saws. This is a very nice kit for both the pro and the handyman. This kit allows me to get to a job and install recess lighting or door hardware. It even has a saw or 2 we used in radio installation work. It comes with 2 arbors and spare pilot bits. The kit also comes with a recommended rpm guide for saw size and material type. I tested mine on aluminum both dry and oiled. I don't recommend oiling but cooling the saw by just using proper speed. Quality of the saws in the kit is the same as the individual saw packages that hang on the hook.

Fantastic upgrade !! I have a collection of miscellaneous hole saws, which I acquired based on project need. Unfortunately, it seemed like I needed a new bit on a regular basis particularly when I was working on my new game room or garage. I picked out this bit set because it has such a wide variety of hole saws and the larger ones have positive locking mechanism, which makes a huge difference when cutting larger holes. The fact that this set comes in a single plastic case makes it easier to carry around the house or garage. The saws themselves seem to hold up well.

This set has 13 sizes of hole saw, and two sizes of arbor. Also included are spare arbor starter drill bits and a very nice plastic case. The larger arbor needs to be used with the larger hole saws. Sawing through any wood is a breeze with these. Removing the plug, which can be a hassle with other hole saws, is made easy by the multiple approaches provided, which help keep the saw cool while being used. See my video for how easy it is.

I received the Milwaukee 21 piece Hole Dozer, item 49-22-4171, the other day. I got this for my husband’s birthday because for years he has always had an incomplete set that didn’t have a case to keep them organized and all in one place. This takes care of that problem and offered him more sizes than he had. It has 13 hole saw sizes, 2 arbors that were easy to change, an Allen wrench and 3 pilot bits. He liked that it had a big enough slot to get a screwdriver in to remove the plug. They can used on wood, metal, pvc and more. He loves the kit, was impressed on the quality of the product and is looking forward to using them. Attached is a picture of the first hole he drilled! I would highly recommend this kit.

(What's this)
This kit contains 21 pieces. There are 13 hole saws ranging from ¾ inch to 5 inches, two arbors and three additional pilot bits. One of the arbors is for the larger hole saws and the other is for the smaller. The larger arbor has a push on and pull off locking feature that locks into the holes on the larger saws. The arbor is screwed on and then the lock feature is engaged. The large arbor is used with saws 1 ½ inch and larger saws. The small arbor is the standard screw on. It is used with 1 1/8 inch and smaller saws. A supplied Allen wrench is used to remove the pilot bit and to insert a new one. The arbor screw for release of the pilot bit is tight the first time and it takes some effort to loosen it. The saw has plug release holes on the sides for easy removal of the cut- out material. The saws are advertised for multi material use, including wood and metal. I have not used it yet on metal but cuts fast and easy through wood. This kit does not have all of the saw sizes available, but it has most of them. Impressive arrangement of sizes. The molded carry case keeps the saws organized and easy to transport. A little expensive but should last a long time. The saws have a limited lifetime warranty against saw tooth breakage.

(What's this)
Over the years, I’ve gathered a miss-match collection of hole saws. Some inherited from my father, others when I needed a certain size and ended up buying one at a time. I always wanted a complete set, and now I have one. One of the best features of the Milwaukee hole saws are the large clean-out slots to pull the plugs out. I also like the way the saws are stacked in the case, to minimize wasted space. I do have an older drive arbor (don’t know the brand) that uses a detent system to engage and disengage the drive pins. I like this better than the Milwaukee system that requires you to spin a nut down to hold the drive pins into position. However, it’s not a big deal. Another feature Milwaukee calls out is their “Rip Guard” tooth design to prevent breakage. A couple of my other brands have broken teeth (see picture). Milwaukee includes a chart for desired drill speeds in different metals, with the different sized hole saws. I wish this would have been printed on a hard plastic, instead of just paper. They didn’t suggest it, but I always use cutting oil when cutting holes in metal. Helps keep the cutter cool, and last longer. Anyway, this is a very nice set.

Milwaukee Hole Dozer General Purpose Bi-Metal Hole Saw Set (21-Piece) is a great set of hole saws. The kit come with 13 hole saws sizes ranging from ¾ “to 5”. Five pilot drill bits, two arbors an Allen wrench. It also come in a nice hard plastic carrying case. The saws are marked in standard and metric. They have two holes on the side for removing the plug one near the top for thinner ones and a longer one for thicker ones. Each saw is backed by the Rip guard limited lifetime tooth break warranty. Even though it says bi metal saws it cuts through wood with ease. I use them on wood most of the time. I highly recommend these saws.

I have been using Hole Dozers for years, purchasing them individually a needed. They can be used on metal, wood, plastics and most building materials. This set has 13 hole saws, along with 2 arbors (requires 3/8” or larger drill chuck) and 3 additional pilot drill bits (1/4” dia). Also included is a hex key used for setting the pilot drills to the arbors. The hole saws have multiple oblong leverage holes (plug jacks) to aid in removing the cut plugs. Multiple leverage holes are provided around each hole saw – the number will vary depending upon saw diameter (see photo) These saws are coated with a low friction thermoset paint - when compared to non coated hole saws, these are noticeably faster - this coating along with the 8% cobalt in the saw material probably contributes to the ease of use. Putting a hole saw onto the 3/8” arbor is straight forward, just spin it on to seat. The 7/16” large quick change arbor does require another step: 1) spin the hole saw onto the arbor to seat: 2) back off the hole saw to align the collar pins with holes in the bottom of the hole saw and push the collar to engage the pins, an internal spring & ball bearing detent keeps the collar in position. Although these hole saws have a limited lifetime warranty against tooth breakage (due to defective material or workmanship) – no warranty card nor any written documentation was included – Milwaukeetool.com has the warranty information. 21 piece set: 13 hole saws, 2 arbors, 5 pilot bits, 1 hex key
