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

Very happy with it. 4 hard wood projects and still as sharp as when I got it. Definitely recommend.

Smooth cut and seems to work well. I cant attest to the longevity of this bit yet, but the initial cuts look great.

to us on the bit on an CNC you have to have the specification for the bit. required is speed cut rate and other. the YOKISHUM has no web link and can not find the name in the web.

Does a great job of putting a very fine finish on my carving projects.

This is the most delicate bit I own, though admittedly I have little experience with small ball-end bits. Still, because of the combination of availability and quality this is my go-to bit for detail carves.

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.

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. Im glad to have this in my inventory of bits.

This CNC router bit by Yokishun is a ball nose end mill bit that is made incredibly well and it cuts perfectly! I use it more for end milling rather than side milling and finish machining, but I have no doubt it will work for any of those applications. I highly, highly recommend it!

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.

Im fairly new to using ballnose bits. Ive 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 havent noticed much difference between bits with the nano coating and bits without, but I do hope it increases longevity over time.
