I installed a new butcher block counter top that overhangs about 1/4" too far. Now the stove is kinda squeezed too tight.

The problem is if I remove the counter top to trim it I will have to redo a lot of finishing work I did on a seam. I want to trim it in place.

I tried to practice trim a scrap piece of the counter top with a cheap flush trim router bit from amazon I bought a while back and it was a fiasco. Glad I didn't practice on the one I need.

Any suggestions or ideas to do it right or brands of flush trim bit to buy?

I want to flush trim it to the existing installed cabinet box.
