EANOSIC Downcut Spiral Router Bits 1/4 inch Shank, 1/4 inch Cutting Diameter Solid Carbide with Nano Blue Coating CNC Router Bits End Mill for Wood Cut, Carving

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.

This bit is very well made sharp and stays sharp. I used it to groove drawer boxes for 1/4” babel to fit in the bottom. I put about 100 linear feet of hard maple through it 1/4” deep and it stayed consistent and did not burn the bit. Highly recommend this product.

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.

Great for C n C machine. Works well to cut 1/4 inch rounds and juice grooves for cutting boards

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.

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 was using this with my trim router, and so far it has been working really well. Cut out some openings in thin wood (plywood), so the material wasn’t too challenging. Clean. Smooth. No burning. Based on the product description it works with a variety of materials.

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

Good quality
