I need to make a 5/8” groove, 1” deep, several feet long, in the underside of a workbench.

Can I use make multiple passes with a straight bit, or do I need to buy a upcut spiral bit?

Yes, you can do this with a simple straight bit. In fact, that may be the preferable way to do it. I say that because with some wood, an upcut spiral will create a little more tear out at the edges.

I would recommend taking no more than 1/4” with each pass and keep moving at a slow but steady pace. If you stop, you will create a burn mark.

Finally, nothing is more important that using a sharp bit.

I’d do it in several passes with a straight bit. Same thing if I was using a spiral bit. It’s about how much wood you’re removing at one pass, you don’t want to overwork your router. You also don’t want to travel too slow. (leads to burning)

I usually travel about a foot in ten seconds. If the router slows too much I lessen the depth of cut, but keep the feed rate up so I don’t burn.

Have your say...
