KOWOOD Tongue and Groove Set of 2 Pieces 1/4 Inch Shank Router Bit 3 Teeth Adjustable T Shape Wood Milling Cutter

I bought these to put some grooves in the bottom of some sliding barn doors and it did a great job. I am sure the other cutter will work just as well and I am milling up some spruce now to make some tongue-and-groove siding. They run effortlessly in my DeWalt trim router.

Worked great made a decent cabinet door for my first time using it

I am relatively new to woodworking, and I bought these router bits to build cabinets as a substitute for a table saw that I don’t have. I don’t have a router table either, so I used these in a handheld router. I made some pretty dangerous mistakes my first go around— so hope this helps.These bits are rated for a much lower RPM than the fixed-setting hand router I had, so trying to use them when they’re spinning at 26k rpm caused some crazy kick back and cut out. I wised up quickly and bought a variable speed router and brought it all the way back to 10k and they actually worked great.I made 6 cabinet door frames with these and by about the 4th frame the bits started to dull and I had to make my passes shallower and slower to minimize the cut out and the occasional kick back. For the price it was worth the purchase, but if I had any larger of a project I would’ve opted for something different. Probably not meant for a hand router but it worked in a pinch.

Works perfectly

High quality bits!

Made it through maybe 20 board feet before it lost its bite. Next time I’m buying a brand that has a reputation for quality.

Not much to say these are great bits and have made doing tongue and groove on the router really easy they are still sharp and functioning great would definitely buy again I've gotten my money's worth already.

These worked perfectly
