You can use a router table with a drill press. If you're not sure about this option, I would recommend reading my post on making a cnc router table
In this post we are going to discuss how you can install a cnc router machine with drive system which is quick and easy option to drill holes in your door lock. The most important part of making a good door lock is correctly drilling the holes. You don't want to ruin your lock trying to use a bad router bit
You will need to make sure that the hole is straight enough for the screw head of your new lock, so you will have to make sure that it's perfectly aligned with your existing lock installation or else you may end up having problems with your new lock installation!
