This is a little trick I use cutting holes with a hole saw .
The way I do this is by marking the hole outline with the hole saw first and then drill another hole inside or outside of the cut line depending on which part is the waste material .
By drilling the small hole it gives the hole saw an escape route for the saw dust which makes the process faster and pretty much eliminated the burning of the wood especially with plywood where a lot of glue is present .
Doing this will also help the hole saw stay cooler keeping it from warping and burning the hole inside face .
