Tongue and Groove Router Bit Tool Set with Adjustable 1/4 Inch Shank T Shape Wood Milling with 45 Degree Lock Miter Router Bits 3/4 Inch Stock Joint Router Bit for Wood Drawer,Window,Cupboard

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

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.

Tongue and groove works ok but the miter bit is dull and burns the wood (pine) tried different speeds but no luck best advice is spend the extra money for good ones

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.

The quality of construction and cutting edges seem good. Be prepared you will need to re-shim the tongue cutter as the space between the cutter heads is too narrow and means the tongue is too thin. The whole point of tongue and grove joints is joints that line up flush, with the undersized tongue the joints have 1/16th of an inch of slop which is counter productive and makes a weaker joint. Take the nut of the top, add a washer on top of the bearing to shim it, test it. You can thin the washer more with sandpaper or a file if you need to further fine tune it.

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.

I have been using a biscuit joiner in my hobby work but perfect alignment on butt joints is a challenge. Joining two 45 degree boards to make a 90 is even more of a challenge. I have been getting by but not without a great deal of sanding to match surfaces.With these bits, some finish sanding was still required but nothing like was needed with the biscuit joiner. The boards on the chest lid, in the attached photo, we're joined with tongue-in-groove. The corner joints were cut with the 45 router bit.

adjustable if you want it to be a snug grove for clamping boards together, or a loose sliding type.
