I love the clean lines this bit makes. I know what I was getting into before getting this bit. It is a down cut so I reduced my depth on each pass to ensure I dont overload my machine. I havent upgraded my router yet and Im still running the original 300-watt motor. If I had a stronger router, I would feel more comfortable going a little deeper and faster per pass. This is due to the waste that comes out of the cuts being forced down vs up and out. In the end though, I have good looking final products with little cleanup to do on the edges.

I got this bit to help with a big roughing project I was doing - building out parts from my x-carve for some furniture. I really wanted the 1/4 size and this fit the bill perfectly - not just for size. It was so easy to use this thing, and the carbide construction and coating on the blade added a lot of precision to the job. The bit is super sharp, and it was not even burnished once I was done cutting out multiple instances of a 3/4 plywood stool I was building. In any case, its a great bit, and Ill like it even more when I use it for some projects that dont plunge all the way through the material.

This is doing its job just fine of creating dadoes for 1/4 luan plywood to rest in. Bit was sharp out of the package and seems to hold an edge, at least in softwoods. I have not had a chance to run it through any walnut yet. Not sure what if anything the blue coating is doing besides being blue. If extended use changes my opinion I can update this review but initial impressions are 4/5 stars.

As a CNCer I go through a lot of bits, either wearing them out or on occasion, breaking them. Its nice to find quality bits at a reasonable price. I dont do a lot of batch work, just one offs for friends and family. So, I am always looking for deals that I dont mind throwing out when I mess them up. These fit the bill. Very happy so far.

I used this bit when I made a cut in MDF board. It cur well and let a smooth edge on the board. I would buy this bit again.

This router bit works great and is a great value for the money!

Had to cut a series of narrow dados for a shop cabinet in prefinished 3/4 birch plywood. Needed a smooth cut that didnt tear up the veneer. Ran 35 of dado without a problem and the bgit remains sharp.

Cuts great and leaves smooth crisp edges. Perfect for what I needed.
