I have a large project to do which involves cutting 12″ precise holes in 3/4″ maple plywood. I need to cut hundreds of holes which means a saber saw is ruled out.
I’m looking for a tool that will produce productivity. Any suggestions?
Thanks.

Rig up a jig for your router with a center hole in the work piece and pin on the jig to fit.
I agree on the router. If you have hundreds of holes, go to a machine shop and have them make an aluminum template ... should last longer than plywood.
I'm sorry, I thought you wanted it done the right way.
Yep, router jig. The only way to go. Some routers actually come with a circle jig, but I've always just made one out of plywood.. Although I can see where an aluminum one might be a bit more stabile and last longer.

Router with an outside template large enough to clamp down.Use straight bit with bushing or top bearing flush bit. With bushing you have to make template larger to accomadate bushing diameter.

ROUTER . THE ONLY WAY.
I'm throwing in with some of the rest here. Router and template. If it's higher production speeds you're after, the plate with hole is the way. Invest in a carbide upcut spiral, you won't believe the difference in feed speed and cleanliness of cut.
If it's really high speed production you're after, hire it cut on CNC equipment.

Upcut spirals are nice for drilling or cutting from the back. I prefer a downcut spiral for fine veneers or inlay work - less splintering and tear out on the face of the material.
Another vote for router and jig.

True indeed. I'm assuming 1/4 dia. bit, probably have to take two passes to get through 3/4 material, so first pass would feed chips into cut if using down spiral. Possibly better to cut from back if possible.
A little more info about job and available equipment might be helpful.PJ

No point in sweating thru all that work with a handheld tool. Find a large woodworking or cabinet shop that has a CNC router and have them do it. It will be much quicker, very accurate, and you'll probably be surprised at the price. Most of the shops that have those machines have huge lease payments on them and are happy to take in work. A good way to find a shop that has CNC is to call a couple of small cabinet shops and ask... lots of cabinetmakers farm out machining to the bigger guys. You could also find the distributors that deal in Komo, Busellato, Morbidelli, etc... call and ask them who has equipment in your area.
