IRWIN 2-3/4 in. L Bi-Metal Door Lock Installation Kit 1 pc.

Saw a youtube video on this and decided to try it....worked great.

Great little tool. Sure makes putting a deadbolt in a door easy.

This product was packaged well and it worked great on my Steel door . It cut right through with no problems whatsoever so ever ! Everything lined up great as well !! My new dead bolt went right on with no issues ! I do recommend this product for metal and wooden doors .

I bought this Irwin Door Lock Installation Kit this week. WOW, what an innovative tool that helped me installed 3 sets of locks very quickly and easily in our rental property in Western Australia. Congratulations and thanks to the Team at Irwin for this ingenious design. I highly recommend this kit. I had 2 other Door Lock Installation kits but this one rendered them redundant.

I have had this jig for over 5 years now and have installed over a 100 locks. I think al lot of the complaints I see are do to forcing the hole saw. Drill in half an inch the back out and extract the saw dust. once pilot bit is through opposite side of door pull drill out and drill from the opposite side to prevent tear out.

I've seen all of the negative reviews on this product and I just don't get it. Almost all of the issues and problems discussed in these reviews could've been solved or never would have happened with a little knowledge of tools and reading the instructions. This is not a heavy duty kit meant for daily work, but it is capable of being used to install several locks. The small "router" bit is a little gimmicky and doesn't work great, but other than that, this inexpensive kit will get the job done.

Worked great on both wood doors and metal doors to keep the 2 holes in line and square with each other. Where it fell short was when you tried to use the router template with the router bit. The router bit just chewed up the plastic template. The template need to be made out of aluminum. I was able to jet out a template from 3/16" AL and got it to work. I didn't buy it for the router template, but I thought it would be a novel idea to try, it failed.

Bought this kit to install new door handle and deadbolt to metal door. Attached the 2-1/8" hole saw to the bit/mandrel and it screwed right down. Didn't know it came apart so it would fit into the 1". Had a heck of a time getting the piece I cut out of the long hole saw. Bolt pate template for router is plastic and it melted half way through the job. Should be made of metal. I would be willing to pay more bucks if this kit came as an all metal unit. As it stands I could only use it for one door. They have a great idea but needs to be improved.

Had this given to me by a family member, and the day came when I finally got to try it. we decided to put a deadbolt on the door leading to the garage. Worked ok on the inside of the door. However when I tried the outside of the door, all it hole bit was able to do, was scrap off the paint. nothing left in the bit to finish the Job. One side of an external door and done. I will still us the template to finish the job, but will need a new hole bit

This is a great idea and was a great product, until the 1" hole saw didn't thread onto the mandrel. Apparently when you use the larger hole saw the adapter tightens and you need to remove it before you use the small hole saw. Good luck unless you have a drill press. I call it a terrible product when you have to go the store and buy and SECOND hole saw to replace the one that doesn't work. Major fail for Irwin.
