I drilled several holes in my desk to put some grommets using a 7/8" hole saw bit. Unfortunately, I realized afterwards that the hole was supposed to be 1" to fit my grommets.
Then, despite knowing better, I used my 1" hole saw bit in an attempt to make the holes the correct size. Although I was able to make the hole larger, the new hole did not come out clean at all.
The obvious solution to this would be to clamp a piece of plywood behind the hole to use as a pilot. However, the position of the holes make this solution pretty unfeasible - they are in the back of the shelf of a large hutch - i would need to get a very long piece of wood with some huge clamps in order to make that solution work (unless I am missing something):
What is the best way of fixing this? I could get the next larger size of grommet (1.5") and make the hole larger, but which bit would be the best for this task? I have never used a Forstner bit - but it looks like it might be promising. Thoughts?
