WREOW Tongue and Groove Router Bit 1/4" Shank Grooving Router Bit Wood Milling Saw Cutter New Woodworking Tools 3 Teeth T Shape,2 pcs

These bits are amazing. I’m using them on my second project right now and still no splintering so no need to sharpen them yet. I’ve used them on soft and hard woods and they do fantastic on both. For the price, I can’t see how you can get better than Yonico. I use them for all of my router bits. I’m not an expert and I would buy a better bit if I used them daily or even weekly.

Works like magic, already did some jobs with it and it perfectly match. It looks like high level product build to stay after us. Materials are good and it's very stable. I like this one and going to buy some more of it.

Seems to work well. Using it to redress some edges.

Ok

These are dangerous! The shank is too long for practically all routers. There is no list on compatibility of these bits to what router they should be mated to. I plugged mine in and tightened it and turned it on only to have it shoot out with dangerous speed. You may be able to cut the shank to the right length, but there are no instructions as to if this is even an appropriate fix. I am frustrated that I have to pay $5 to return such garbage, but I guess it is worth it if I get to keep all my fingers and eyes. DO NOT BUY THIS unless you are 100% sure it will fit your router and you are willing to risk taking a chance that the shank will fail and send the bit into your hand or face!

Great

I used the router bit set to make a shaker style door for a pantry, and a toy box for my grandsons. And for the price it worked great

I purchased these last year and cut 6 boards with them to test them out. Everything seemed fine so I put them away until I needed them, which was today almost a year later. I cut a couple grooves in some 7/8" oak and everything was fine for a couple boards and then one of the cutting heads flew off. I saw the spark when it flung off my metal router table so I shut the router down immediately and began investigating what failed. I looks like the carbide was not properly secured to the cutter head.Edit: I contacted the seller and they replaced the faulty product immediately. Their customer service has been excellent.
