I need some help understanding this I have been looking at router speed control box. I have never used them and I’m thinking that this will help with burning and tear out. But I’m not sure how to figure out what speed to use with what bit is there a chart that tells you. I like to make stop chamfer and I’m get burn at the end I know you have to keep moving but I do slow down so I don’t over shot the stop. I’m thinking a router speed control box will help with this I’m thinking I might be right but not sure.Also has any one used the freud quadra bits yet and what do you think of them. Thanks for reading and you help

A lot of router bits show the recommended speed on the paperwork accompanying the bit or in the listing information on their web site. Basically, the larger the bit diameter, the slower you want to run them. This website has a router speed Chart that shows basic recommended speeds based on diameter.

Cheap bits wont go far on hard woods, I had the cheap menards set- useless except on pine.

>>>A lot of router bits show the recommended speed on the paperwork accompanying the bit…....

Those are typically maximum speeds, and not ideal speeds. For bit’s 1/2”-1” diameter, around 16,000 rpm is a good starting point.

If you’re getting burning, you may need to feed the wood faster into the bit. Regardless of the rpm, if you feed to slow, you’ll get burning. Some woods are more susceptible to burning, especially cherry.
