What We Don’t Like About Flytuo 1/2“ Shank 45 Degree Lock Miter Router Bit
Although the Flytuo router bit is made of high-quality materials, it only comes in a single size. If it doesn’t fit your router, you won’t be able to use it. This takes away from its versatility even though you can use it with CNC and portable routers.
Additionally, the Flytuo router bit is prone to overheating at high RPMs. To keep it from burning the wood, you have to constantly add water to cool it off.

What We Don’t Like About HandsEase 45 Degree Joint Lock Miter Router Bit Set
Installing the bits into your table can take a while, especially if you plan to change them out regularly. If you are not patient, you likely will not enjoy having to make frequent adjustments.
The medium-sized router bit is also a bit small, meaning that the cuts are not exactly perfect. This does, however, leave enough room to add wood glue to further lock the joint.
One final note, these router bits are not suitable for plywood.

What We Don’t Like About NITOMAK 1/2” Shank 45 Degree Lock Miter Router Bit
Unlike the other entries on this list, the NITOMAK router bit is constructed using C2-grade carbide blades rather than C3-grade carbide blades. Although you won’t have to worry as much about the blades chipping, a lower grade carbide will cause the blades to dull sooner.

Its hefty weight and large overall diameter make it a beast on the router table that can withstand high RPMs and dense woods without knocking about or coming loose. It is reliable and will undoubtedly speed up your woodworking.
What We Don’t Like About Whiteside Router Bit 3362
Although we just praised it for its hefty weight, the Whiteside router bit 3362 is too hefty to be used on a CNC or portable router. Therefore, you will only be able to use it on a tabletop router, making it less versatile than some of the other options on this list.
Additionally, this router bit has been constructed using C2-grade carbide blades instead of C3-grade carbide blades. As we mentioned in the previous entry, this means it will dull sooner, despite having a lower risk of chipping.
One final complaint about this router bit is that it’s the most expensive on the list. Although it packs both high-quality and a literal punch, the price point could scare off potential buyers.
- High-quality craftsmanship

After reviewing all five locking miter joint router bits, we have concluded that the NITOMAK 1/2” shank router bit is the best in class. It combines the best features of all other router bits on this list while still coming in at a reasonable price.
We love that it is versatile enough to be used on a tabletop or portable router without sacrificing power and precision. Its versatility also extends to the range of woods it can cut. Many other options fail to cut MDF and plywood without shredding but the NITOMAK can do both.
Finally, although its blades are built using a lower-grade carbide, we love that the full body has been coated to protect the router bit from wood resin and sawdust. This will help keep the router bit stay in top condition for much longer than other options made with a higher-grade carbide.
The NITOMAK manages to outperform its competition without breaking the bank and, for that, we award it our top rank!
