KATA 1-3/8" - 1-3/4" Door Lock Installation Kit for Wooden Doors with Guide Template,Door Lock Hole Saw,Carbon Steel

This is a great kit and has given me exactly what I needed to convert some older doors into modern hardware. I had to redrill the latch bore because it was too small in all of the doors, and sometimes had to redrill the recessed hole for the latch because it wasn't lined up or deep enough. Attaching it to the door with screws before drilling kept everything steady and made the process much faster. Sometimes the nut that holds the saw in place comes a little loose, but I just need to be careful to tighten that more before use.

I was doing this for the first time as a DIY and the results turned out better than I had expected. There are some concerns when using it such as the hole guide being wobbly if you are using the guide extended. I extended the guide to 2-3/4" backset and there really is no locking mechanism (at least that I could see via instructions), so preferably pre-drill the center point before going straight in to avoid misplacement. The hole saws worked well but I do see them not lasting if you are doing a lot of doors. As some have mentioned also, make sure you double check and measure that its centered because it doesn't exactly fit flush, and sometimes has gaps on both sides. I won't fault the product though because it got the job done.

Perfect for door locks drilling correct size.I am happy
