I just got my hands on an affordable Bosch router table and installed it flush into my workbench. I'm currently using a basic corded Dewalt 1/4" router with it. My first project is cutting rabbets for some picture frames, but I'm running into issues. When I push the red oak stock (3/4"x3/4") through, there's a lot of chatter, and it feels like the router grabs and cuts unevenly. This happens no matter how slow I go or whether I'm cutting 1/4" deep or 1/8" deep. I understand that 1/4" might be pushing it in one pass, but I thought I'd give it a shot. I'm using a 1/4" shank, double flute straight bit. What's the best speed setting for hardwood with this setup? Should I be using a different bit for rabbets? Any tips would be greatly appreciated!

Yeah, a bit of clatter is usual, but it sounds like yours is over the top. Are you routing the rabbet in the individual pieces rather than the whole assembled frame? The direction you feed the stock is key, but that can get tricky if you’re working with completed frames. As for speed, a fast setting is typically good for the bit you’re using. A 1/2" shank bit would cut smoother than a 1/4" if you have access to one. You mentioned the depth of cut, but how wide are you making those rabbets? It sounds like you might be burying the bit too deep, which can cause issues with chip removal. There are definitely several variables in play here. Let me know if you have more info, and I’d be happy to help you troubleshoot further!
Good point about the depth vs. width! Definitely try to make sure those chips have space to escape—too deep and you could be causing a jam with all the wood shavings. Keep an eye on your feed speed and adjust your bit height accordingly!
Thanks for the input! Just to clarify, when I cut, the rabbet width is either 1/4" or 1/2", and the actual depth the bit protrudes is around 1/2". I’ve set the bit ahead of the fence and am pushing the stock along the fence (from right to left). These are just straight pieces, not assembled frames yet. I thought the bit might be dull, but it’s barely used, only for shallow cuts before. Any other advice?
