It should work well with a fiberglass door.

What is used for the door frame?

Asked by Njc May 9, 2020

Answers

This kit does not include any tools for installing the strike plate on a door frame. I would recommend buying a door with the area for the strike plate already routed out. If that is not an option for you then you'll need to chisel out the strike plate area on the door frame yourself or hire a professional to do it.

Does this help to enlarge the existed hole?

It didn't work for me. The clamp doesn't stay in place and when it moved, the saw also moved and damaged the surface of the door next to the hole.

The pilot bit was snapped. What is the size of it? Need to buy 1 to replace.

Asked by MuMu October 14, 2019

Answers

This tool was supposed to be for DIY idiots like myself, and it worked for the most part except one of the larger drill bit got jammed and I couldn’t replace it with the smaller drill bit. Actually took the piece to Ace Hardware, where they put the piece in a vice and was finally able to detach it with a plumbers wrench. The holes were cut very cleanly though. PRO TIP: I think about the hole that the bolt retracts into.

Can this be extended to work on a 2" thick door?

Asked by David April 15, 2019

Answers

I checked the one I bought about a week ago. The jaws will open to 2", however, there are rubber pads on both side of the jaws to protect the door. I think the maximum door thickness is more like 1 7/8 and it may be a tight fit then.

NOT for exterior door ise
I would not recommend this at all, got the knob hole drill in with some extra effort, but when it came to the deadbolt hole, it was a nightmare, barely cut the one side an jammed numerous times when it hit the other side, had to finish the hole from the other side an still would jam an even snatched the drill from my hand, do not buy fr metal doors...

Perfect installation guide!
Worked perfectly to cut the proper holes for my door. The set comes with eveeything you need to be able to properly install a door knob. There are two settings on the guide to be able to cut holes for all standard door knobs. Very easy to use

Worked exactly as it was supposed. Much better than ones I’ve used in the past. I used it on a steel door and had no problem drilling clean, even holes on multiple doors

This Milwaukee Door Lock installation hole saw set (49-22-4073) is great up to one little critical point: the 2 1/8" hole saw doesn't really cut a metal door. I showed the Milwaukee rep at store HD 4040 the evidence, including the cookies cut out (barely) and the worn-out hole saw after just ONE hole. On the cover it states "metal" stating that it will work for a metal door. My rating: 5 stars for the jig, and 1 star for the hole saw. I can't recommend it unless you only do wood doors. * The jig is slick - takes out all of the guesswork. * If you do metal doors a lot (I do) you will want to order 49-56-9210 or similar. * They conveniently added some drill bits for the screws. Be careful when opening the package or you will lose them (loose). Since I do these types of doors a lot, I kept the jigs (which is handy) and ordered the upgraded hole saw (49056-9210). I am adding a picture of the worn-out teeth on the hole saw.

Don't trust the clamp
It feels secure until you start, then it spun out of place and nearly ruined my door. Thankfully, the door wasn't ruined because this sub-par hole saw couldn't saw all the way through. So, a terrible clamp doesn't do as much damage if the hole saw is just as bad. I should've gotten the Ryobi door kit (I didn't because it screws in place instead of clamp.... joke's on me, I may need a new door in attempting to avoid two screw holes).

Worked pretty well. A hole is drilled in my door, so it accomplished its purpose. I didn't expect the amount of kickback the drill would have and twisted my wrist a little. Rookie mistake I suppose. Like some other reviewers, I got some plastic shavings from the inside of the larger hole. Make sure you have fully inserted the bit before you start. I think mine must have just been mostly in but not completely. Doesn't seem to have harmed the tool. Also like some other reviewers, I found it absolutely impossible to unscrew the five parts that came together to form the larger drill bit assembly. I finally managed to separate the arbor from the rest of the parts, but the other four I think are together for life. For those who desperately try the hex hole, it only releases the pilot bit. Anyway, after the workout of trying to disconnect that, I connected the edge hole bit directly to the arbor and it worked fine. I have not tried to unscrew it though...

Fantastic! Takes out all the guesswork!! Easy to adjust and stays in place ordered it on the web a few days ago for what I thought was going to be a difficult job for an 87 year old. Could have never done the job without it! We always depend on Home-depot and actually built our house 35 years ago with Home-depot!

I had a number of old solid doors to update by adding knobs in place of latches. This kit helped immensely in that process. I did notice during use that some of the plastic would grind off of the cuff and while it was a concern at first it never impacted the usefulness of the device.
