CNC Router Bits 1/4inch Shank 1/8inch Cutting Dia Carbide Ball Nose End Mill with Nano Blue Coating for Side Milling End Milling, Finish Machining (1/8"x1/4"x2")

This bit does exactly what one would expect it to do. It is sharp, but so are all bits when they are brand new. The blue coating is supposed to keep it sharper and longer lasting. I have yet to use it long enough to compare it to others, but I feel reassured that it will outlast non-treated ones.I'm glad to have this in my inventory of bits.

looks like a great bit, haven't tried it yet, but i expect it will do the job well.

Very sharp I use it in my 3D engraving. It has held its edge very well after many hours of use. I get a clean burr free cut.

I'm fairly new to using ballnose bits. I've primarily used V bits and flat endmills for the past couple of years on my CNC machine. However, I recently started to experiment with ballnose bits and cutting from some basic 3D files.As you can see in the photo, I made a mancala board and used the ballnose to shape out the bowl shapes. While you do need a decent bit, 90% of the end result is how you set up your file and toolpaths in the software. That being said, I felt like I got great results with this bit. The cut was sharp and it performed as I expected. I haven't noticed much difference between bits with the nano coating and bits without, but I do hope it increases longevity over time.

This bit gave a nice cut into premium hardwood. In the photo, I have it at Z -0.1 into the stock for the cut running 16000 RPM. The bottom and sides got a smooth rounded finish and carbide should keep it that way.

Smooth cut and seems to work well. I can't attest to the longevity of this bit yet, but the initial cuts look great.
