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.

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.

These are decent bits but they are not matched and as a result you will have to reset each time you flip from one bit to the other. I thought about sending them back but for the dollars I will try them first.

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.

The tendon cutter blades are not wide enough to remove all of the material. Also, vibrates my router table excessively. Maybe all combination blades do, I replaced it with a round over bit and it ran smoothly.

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

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