10 Best tongue and groove Router Bits
When it comes to quality woodworking tools, Freud stands tall - arguably at the apex of the hierarchy above many other companies. Their saw blades for example are peerless in quality. However Freud is not only known for its saw blades. The European company actually makes really good router bits as well. This quality is definitely not spared in its 1 34” Adjustable Tongue and Groove Bit Set.
This adjustable tongue and groove bit set continues with Freud's renowned design tailored towards precision and durability. It features a unique tongue cutter with sheer angles on the parallel sides. This is to ensure precision in cutting.
Speaking of cutting, this set easily cuts through plywood, hardwood and softwood, providing a perfect balance when compared to lesser bit sets. Not only does it offer precision cutting, but this set can cut softwood accurately in one pass! It will work with you and remain sharp for a long time.
However you may have to get creative when cutting hardwood. The bit size might not lend itself to accuracy in this regard. Thankfully, the adjustability factor solves this issue most of the time.
On Amazon, the 1 ¾” tongue and groove set received an average review score of 4.6 out of 5 stars. All reviewers agreed that Freud's quality is on display here and it justifies its price. You will find tongue and groove bit sets for less, but they will pale in quality.

The Yonico 155221 is not as high on the food chain as Freud’s products, but it holds its own - to some extent at least. As is the standard with tongue and groove sets of this nature, these are carbide tipped and lend themselves heavily to precision cutting. It is recommended for stocks of up to 3 ¼” and handles itself well on a variety of wood grains.
Well, this router bit set is certainly well presented. The package contains the router bit with extra shims, all of which neatly fits in a handsome wooden box.
As a router bit set, it does the job, however with this product Yonico assumes that you have a strong router. It is very finicky with weaker routers.
On Amazon, the Yonico 15221 has an average review score of 4.4 out of 5. Many of the reviewers agree that it does just enough on softwoods such as pine, but struggles with hardwood. Many complain about burning board ends, a tell tale sign of dull bits. This is to say that this tongue and groove bit set does not hold up well as it relates to longevity.
CMT jumps into the tongue and groove market with this one. It advertises it specifically for ½ inch mission style cabinet doors. This cements the 800.625.11 into that niche. The question is: is it the best in its singularity? Well, it certainly holds its own going toe to toe with the top tier brands.
This tongue and groove set comes with two carbide tipped cutting edges and is designed to limit kick back. It does a good job on plywood and softwood and does an ok job on hardwoods.

However some marked it down for not having a 3 ¼” shaft, which is the optimal size for the average project.

Again, Yonico thrusts itself onto our list with this offering. The Yonico 15423 like others in this category has a ½ inch shank. It is specifically marketed for creating grooves in flooring, stile and rail projects. However the Yonico 15423 may find purpose elsewhere as well.
This set boasts C3 micro grain carbide blades aimed at prioritizing sharpness and durability. Like other Yonico products, it does the job that it is intended for, however we would be lying if we were to say that this is the best product out there.
Sometimes a lower price betrays a lower quality and while the 15423 does its job, it is not as durable as it claims to be.
On Amazon, the Yonico 15423 has an average review score of 4.5 out of five stars. Many state exactly what we have stated, that the product is just ok, doing its job with purpose.

This next entry from Yonico is recommended for use on slim pieces of wood. This is where it's advertised precision is best displayed. It is for use only on router tables and does its best work when used with a heavy router.

As a company, MLCS holds its own against the biggest and the best in the industry. This quality is on display here in the MLCS Tongue and Groove V Notch Set.

This one sneaks in at a very affordable price point and markets itself as a versatile set. The Yakamoz ½ inch Set holds its own when used with high speed routers. However they are not drill bits and we will give you this disclaimer. They do not work with drills. The T shape of its design allows this set to achieve some balance, as it features a +/- .003 level of tolerance.
This bit set is a two piece set. It is cited as being specifically tailored for hand making drawers. This is because it does its best work on the softwoods and plyboards typically used in drawers. However when it comes to hardwoods you may find that this set struggles a bit. It gets the job done, but there are other offerings that are leaps and bounds ahead.
The teflon coating lends itself to the reduction of heat in an effort to promote longevity. This works to some degree. It lasts for a while, but again it pales in comparison to those at the higher end of the market.
On Amazon, the Yakamoz ½ inch Shank Tongue and Groove Router Bit set has an average review score of 4.1 out of 5 stars. Many reviewers say that it functions as it should, but caution that there are better options out there.

The Rockler Tongue and Groove Bit has a `` cutter with ¼” shank. This means that it will not necessarily work with the same sizes of the other entries on this list. However it holds its own. Once you use a router table and set this bit in a heavy router, it does its job. The Rockler Tongue and Groove Bit is at its best when cutting tongues and matching grooves in softwoods and plywoods, however when it comes to hardwoods you might have some trouble. We are not saying that it does not do its job, but you may have to make several passes. Even then, a higher quality bit may do a better job than this entry.
With this one, you will get two bearings, two slotting cutters and some shims that all lend themselves to adjustment. Once you can find the right configuration you may be surprised at the functionality. It is designed to cut tongue and grooves into ¾ inch stacks. This was quite a surprise when we assessed the size of the groove depth (⅜”.)
One other feature that we found helpful was the smartly implemented ball bearing guide that allows you to easily follow the material thus adding to the precision of your cuts.
Amazon reviewers gave the Rockler Tongue and Groove Router bit a 5 out of 5 average score. They praised the aforementioned ball bearing guide calling it very helpful. However while they gave this one a perfect score, they did mention the fact that it is at its best when used with softer wood.
