Made in the USA, the Milwaukee Hole Dozer Hole Saw features Rip Guard, the strongest tooth form in the industry, backed by the Rip Guard Limited Lifetime Tooth Break Warranty. Each tooth is built with more steel behind the cutting edge for added strength. The Rip Guard warranty on tooth breaks is a first for the hole saw industry. The added tooth strength along with 8% cobalt give added life to the teeth, allowing for increased productivity on the jobsite, as well as continued hole quality. The Hole Dozer™ includes Plug Jack™, an all access slot design that allows for full access during plug removal. The Plug Jack™ gives access lower into the cup for thick material and higher towards the teeth for thin material. With multiple positions to apply leverage and better plug access, Plug Jack™ increases productivity and eliminates wasted downtime between holes. For fast, tool-free change-outs, use Milwaukee's universal Quick-Change Arbors. 49-56-7210, 49-56-7240, 49-56-7250, and 49-56-9100.

Rated 5.0 out of 5.0 by Newbie First time installing a deadbolt into a wooden door. Watched a fantastic door installation professional install my deadbolt , paid attention, purchased a second deadbolt and decided to install on my own. Purchased this kit. Wonderful installation of my deadbolt. Easy and quick. Ladies we, can do this. May 13, 2015
Rated 5.0 out of 5.0 by Works Well Putting in some new doors. Can cut holes manually but this just makes it easier. I have used it on two doors so far and it has worked without a problem. April 7, 2015
Rated 4.0 out of 5.0 by best at it i bought this to enlarge 10 door handle holes to accept new door hardware. it worked great. i would recommend buying a larger abor bit to go along with it, it comes with an adapter but i spend more time trying to remove the adapter then i did install the door knobs. it couldn't be easier to set up and drill, the hardest part is cutting out the mortise for the latch to sit in.

Rated 4.0 out of 5.0 by simple to use My first attempt at drilling a door for a lockset, after reading reviews for other brands this one was the priciest but had the overall best reviews. It was simple to use and the results were better than I expected. Because the housing is made of plastic I can understand how it might wallow out after a few uses, if I had to do this on a regular basis I would opt for something more professional, but for the DIY this worked fine.

Rated 3.0 out of 5.0 by Functioned with some help. I purchased this kit in order to expand the knob/lock holes on two older front metallic foam filled doors from the old 1 1/2" to the new standard 2 1/8". While I understand that was not the original design of this equipment, I had read several places of people using them for such. I found two problems with the kit. First, the clamp is not strong enough to hold the guide in place when drilling a metal door and it resulted in the bit and guide sliding out of position when starting the drill. The rubber non slip pads were good enough though that by adding an extra wood clamp to the edge of the guide it worked well. Probably not necessary for a wood door, but definitely a must on a metal door. Secondly, the inner part of the guide slides back and forth to accommodate either a 2 3/8" or 2 3/4" offset from the edge of the door. However, this does not lock into place well enough and would move back and forth when trying to start the bit. I was able to hold the inner portion in place with my thumb when starting the bit, but made alignment slightly more difficult. Overall, with the simple fixes it worked for what I needed it to do.

Rated 4.0 out of 5.0 by Worked very well. I always wanted to try to install a blank door. I had a house that needed 6 new doors so I purchased this kit. It got the job done, The only thing that was different than the ones cut at the mill is the boring bit for the latch was a lot larger than it needed to be, The plastic housing did wear some during the cutting process so I feel that it is probably good for 20 doors before it would need to be replaced.

Rated 3.0 out of 5.0 by This tool is not necessary I have never drilled a door knob before so I thought I should buy the most expensive jig to prevent messing up a steel door with wood core. I purchased the Ryobi model which turned out useless because of the spring clips that did not hold the jig securely. I didn't even try using it in fear of messing up my door. After I purchased the Milwaukee jig, I realized that I could have just drilled the holes without the jig. Before I even used the jig, I used a speed square to line up the knob hole and latch hole to the existing strike plate hole (on the door frame) In order to insure accuracy I did position the jig and used a pencil to show where the center of the circle was for cutting. I used a punch to guide the drill bit. The jig hole was larger than the hole cutting blade so it really didn't help you to drill a perpendicular hole. I still had to hold the drill perpendicular to the door (top to bottom, left to right) and the jig did not do that for me. I supposed a drill press would have taken care of this but I didn't want to buy one just for that purpose. The large cutting hole was made from plastic and basically got enlarged by the hole saw bit. Pieces of red and black plastic were everywhere after I was done, rendering the jig useless for more than one time use. Now that I have drilled my 1st door, I now realize that I can use a speed square and accurate ruler, all you have to do is buy the hole saw and a 1" blade bit. The mandrel with the guide bit does help to drill the hole from the other side (to prevent splintering the door) I should probably post a youtube video showing how easy it is. Fortunately the 2 hole saws and mandrel are only $10 cheaper than buying the whole kit so the savings is not substantial. June 3, 2014
Rated 5.0 out of 5.0 by great I bought a new number entry lock for my 1973 condo door. I didnt know the hole sizes changed with age so I had to figure out how to get it cut wider. I have never done something like this before and was s bit scare of ruining my door. I googled the item and watched their YouTube instruction video. I bought it and it worked great. I was very impressed. December 17, 2014
