These will be compatible with each other, right?
These will be compatible with the correct bushing also known as a template guide. I checked the description on Milwaukee's site and all it says is that it has an "4-point PM bushing", which is talking about the plunger, not the template guides. I didn't see it in the package contents. If it isn't there you may need to get a bushing that fits the jig plates. Milwaukee has a set that would have all the bushings you would need for this jig if you were to buy more plates for your jig. It runs around $40 on Amazon.
