So at 1/16" these bits are for the smallest of detail work with your CNC, and as such are so incredibly prone to breaking, so it's important to have sharp flutes on it for the cuts you're able to get out of it until you undoubtably accidentally take off to much in a pass and snap the bit. These bits are sharp and get the job done well. They're a decent value for what you get as well, which at this scale tends to be pretty important because of the ease of breaking them. Will buy more in the future.
