A: I tried cutting 1/4" Plexiglass with a router to use it as a template and gave up. The bit melts through the Plexiglass and the plastic then wrapped around the bit. Perhaps I moved the router too slowly. Then there were little shards of plastic left on the workbench. These had to be removed to avoid scratching up other work pieces. There must be a better way to cut it but I haven't found it yet. I don't know what bit would make a difference, these being no worse than any other. I have tried cutting Plexiglass on a table saw and band saw and they're okay as long as you need only straight cuts, but it gets real messy with the hot shards (eye protection!). My best results are cutting it using a special tip that fits in a soldering gun or some wood burning tools. Otherwise, these bits perform adequately in wood for any straight bit with its known 1/4" shank limitations. In general, I prefer using 1/2" shanks whenever possible. If your collet choice is only 1/4", these bits will perform. Just make sure that the bit is very tight in the collet and limit the cutting depth to no more than 1/4" per pass with 1/8" even safer.

A: You certainly can't use them in a table saw like you would a dado, but you could certainly use them in a router to cut a dado. To cut a very deep dado you might to make several passes.
A: Yes, but: These are 1/4" shank bits. If they aren't very, very tight in the collet, then they can migrate out and destroy your work piece. 1/2" shank bits have 4 times the collet surface area and will better tend to stay in the router. In addition, if the bits get a little dull, this is more likely to happen and they can also snap off from the shank. Whenever possible, you will want to use 1/2" shanks. In a pinch, these bits will do.
A: Mstevem, thank you for your interest in the RYOBI Straight Router Bit Set. Yes, you can use a router to make a dado joint.

A: In your router you can use them for whatever you like
A: Hello Tom, Thanks for your question on the RYOBI Straight Router Bit Set (5-Piece) A25RS51. These bits are for cutting grooves or edges and do not have bearings. Thanks for asking! - Eve
A: They are universal. Will work with any brand.
A: I am using them with a Craftsman Router.. The bits are all pretty much universal - they will work great with any router as far as I know..
A: I have used them with Ryobi, Dewalt, and Milwalkee equipment.
A: Thank you Mge for your inquiry. The RYOBI A25RS51 are designed with a 1/4" shank, we recommend verifying compatibility with your router manufacturer to avoid coverage issues. ~Best Regards, Ashley
A: These bits have the standard 1/4-inch shaft. They will work fine in any router with a collet that accepts 1/4-inch bit shafts (which includes most routers). Even my biggest router which is made for 1/2-inch shaft bits also has an adapter to allow me to use bits with the smaller shafts.These work fine in all three of my routers, none of which are Ryobi brand.
