Finding a Router bit used commonly in RV Construction

There's a type of router bit, its used regularly in RV construction for cutting out Windows and vents in panel/plywood/etc... when RV's are constructed.

Usually a full sheet is installed on a wall, once its glue has set, a router is plunged in to cut out the wood over the window or other opening.

What kind of router bit is that? What is that normally called?

From when I watched them do it years ago, it seemed to have a roller or something of some kind on it to keep it from cutting into the framing when they removed the wood for the openings.

Very common flush trim bit. Any woodworking store & most hardware stores carry them.

They are called "bearing guided xxx"

Very common bits designed for template and sign work.

Sears may have them but unknown quality anymore.

Google production router supplies for starters.

Hobbyist here so no clue to current offerings or better/worse companies but there may be others that could provide direction

Many of the bits and different size bearings are interchangeable so that you're able to get the cut you require.

x2 on the flush trim bit, but there has to be some sort of a template for the bearing to ride on while the blades remove the material. Also, a bearing supported bit that has plung capabilities will have the bearing high on the bit with the cutting blades below it. Again that bearing has to have a pattern template to follow to have the blades remove the desired material.

The flush trim bit will have a bearing on the bottom. Grizzly and major tool stores sell them. You might also be able to get'em online or at Lowes/Home Depot.

I buy many router bits from here: MLCS Router Bits and Woodworking Products.

There is a guy that sells decent Yonico bits on Ebay that while not super premium, work well for general work. I have a bunch of them too: Flush Trim 1 2" w x 3 4" H Router Bit Shank Bearing 1 4" Shank Yonico 14123Q | eBay

There is a top bearing bit also. The bearing is closest to the shank. I have seen bits with two bearings, both top and bottom. There are several suppliers. Some of those are WoodCraft, Rockler, CMT, Amana, Freud, & MCLS. I like Amana which are made in the USA. You can search for many of those online through Amazon.

X2 like IC2 said about MLCS,I have been dealing with them for many years, I'm only about 45 minutes from their show room. You can get a flush trimming bit with the bearing on top, make sure you get a bit with a 1/2" shank. If you put to much pressure on a 1/4" shank it will break. If you can precut the opening with a saber saw, and trim with you router, less strain on bit, it's easier to work with the template on top, always work the router left to right facing the edge you are cutting.

I agree with pre-cutting most of the material. Then, use the router bit to remove the remaining material. Trying to make the entire cut with only the router can be tough/dangerous depending on the material being cut. There may be some exceptions to this, but removing most of the waste material is a pretty good rule-of-thumb.

Yes, there is a correct direction for a hand-held router. From left to right prevents the router bit from grabbing the material and pulling the router out of your hands.

The proper direction will also give you a MUCH smoother finish.

When selecting a router bit, look for the types of materials that bit can cut: wood, metal, plastic, etc. Router bits can be made out of different materials (HSS: High Speed Steel, Solid Carbide, Carbide-Tipped) and it can make a difference for quality of cut, the type of material you are routing, and longevity of the bit.

Practice, practice, practice.
