I am shopping for a surfacing bit for a router planing sled. I have found a few that are about 1 1/4" in diameter and am wondering if I should go bigger. My router has never given me issues with lack of power before but I'm wondering where its limitations lie. Its a 12 amp 2.25 HP craftsman with speeds from 10k to 25k rpm. Also wondering if it would be able to run some raised panel bits. Thoughts?
