7. Yonico Dado Straight Bit Undersize Plywood Bit

The Yonico Router Bits will make perfect sized Dados for different sizes of plywood such as ½”, ¼” and ¾”. The major fault in this one is the wrong labeling. For a tight fit, the measurement should be 15/32” whereas it is labeled on the box as 31/64”. It would still have been of little use if the bits were sized as labeled.

The extra gap in a joint is unsightly and provides no strength over a simple butt joint. You can go ahead with this product if you are a newbie or want these for some low household work. If the first cut is not enough, you can get a second pass. The cut you will get out of it will be smooth and clean. The good thing is these won’t cost you a fortune.

Like I said, if you don’t have to take off much wood in one go, then one pass should be enough. The router bits have a nice appearance. The router bits do not heat much when working on softer woods. So, if you are looking for some DIY projects or other little household works to do now and then, the Yonico router 3-bit set would be a great choice.


  • Straight cuts for dressed plywood
  • Micro-grain tungsten carbide blades for a long-lasting edge.
  • Silver induction brazing provides durability.


  • The actual measurement does not match the size mentioned in the label.

Best Router Bit for Dados Buying Guide

Before purchasing a router bit, you should do some research and have some information about the best products that you can choose. The below points will help you choose the right product.

Type of your project

First and foremost, you need to see what kind of project you have at hand. Is it something professional, or have you got to do some basic DIY sort of work at home? The type of your project will tell you what kind of bit you will need.

If you are a newbie, you might just end up breaking the router bit, so don’t go for an expensive one. It will take some time to gain experience. A stile or rail router bit can do the job if you are building a door frame. You can even consider an edge-forming router bit.

High-speed steel or carbide

Next thing you need to decide is whether you want high-speed steel or carbide? HSS bits are made of carbon steel and have high heat resistance. It prevents them from breaking and facilitates extended usage.

Carbide router bits have a longer life than HSS ones. Carbide bits are a lot more expensive and cause a lot of damage.

Shank size

Every router bit has either ½ inch or ¼ inch of the shack. Most commonly, routers have interchangeable collets to accept different sizes.

¼-inch shanks are the most common ones, but the diameter is small, which means it will jump around more than the ½-inch shank. This will result in inadequate control and precision. ¼-inch shanks are a lot more affordable than the ½-inch ones. As the ½-inch ones are more stable, you will have better control. Though they are costly but provide high stability.


A dull bit will reduce the effectiveness of the router and may cause a burn in the material. The sharpness of a router bit shows the ability of the bit to cut through materials easily.

A dumb bit will reduce the effectiveness of the router, causing burns in material and leaving a poor finish. Every new router bit should be sharpened in the factory. It might not be visible when you purchase a new set. You can either sharpen them by yourself or take them to a professional.

Final Verdict

There is a wide range of router bits in the market. You might be a little overwhelmed with all the options you have on hand. If you are looking for bits that can help you with DIY projects and small works at home, you will want to spend a little.
