Tongue and Groove Router Bit Set 1/2 Inch Shank Router Bits for 3/4" Stock, 1/2" Cutting Depth Adjustable Router Bits T Shape 3 Teeth Wood Milling Cutter Woodworking Tool for Doors, Drawers, Shelves

Although I haven't had the opportunity to use them, they are sharp and appear to be quality i will have to review them again later for durability. I plan to use them to build a fishing boat out of 2x12's, and the tongue and groove will ensure it is water tight. Then I will seal it inside and out with truck bed liner. When I get through building it, I will post pics.

I was looking for a decent price for a good quality tongue and groove router bit set. Knowing router bits can vary significantly in price in respect to quality I found this set. The price was reasonable but it's hard to distinguish the quality until you use them. I liked the fact this set listed all the dimensions of the bits in one of the images. That significantly helped me verify these are in fact the type of router bits I needed. I proceeded with the purchase and the bits arrived one day ahead of their anticipated delivery date. After inspecting and using the bits and am satisfied with the quality of the router bits at the price I paid for them. It was also nice they arrived ahead of schedule as well. I would recommend them for any hobby woodworker needing a good tongue and groove router bit set.

I was looking for a more snug fit for my joint.

I purchased these for a hardwood flooring project, should be very handy to be able to put a tongue or groove on the end of boards that have been cut. I have done other hardwood floors and have had to put otherwise good boards to the side simply because they have been cut.The bits appear very good quality, sharp teeth came well packaged and no apparent damage.Will update the review once I have made use of the bits.Update: I didn't use the bits quite as much as expected, however they were indedpensible. I had to make a non-standard width board right at the top of a staircase, couldn't have done it without. Bits cut great, very happy with my purchase.

Bought this several months ago, however did not need it right away. Put the 45 degree miter bit in my router for the first time today and within getting 1/2” into a piece of maple the shaft bent and shot the piece of wood away. The bit continued to wobble in the router until I shut it off. I unplugged my router and was able to turn the bit by hand and see the wobble. Completely unusable. Buy the 1/2 shank. Do not buy 1/4 shank for a bit that is as heavy and large as this.

Meh

Better quality than expected

I made flooring out of recycled lumber. Planed it to thickness and then T&G’d with these. Worked like a champ. Would’ve been better if I’d mounted routers to a router tables and not had to handle each piece so many times. But was for a small space.
