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 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 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.

Downcut bits are my go to for profiling to keep the edges crisp and chip/splinter free. This bit does not disappoint. Great value for a high quality, sharp bit.

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.

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.

Good quality

Smokes badly with MDF. Not recommended for MDF

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

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

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.
