A Ball Nose End Mill, also called a "Ball Cutter", "Ball End Mill", or a "Ball Nose Mill" is an End Mill whose tip is ground in the shape of a half sphere. Ball End Mills are always center cutting, so they can cut everywhere on the ball. We can think of them as a special case of corner radius endmills, where the corner radius is as ...
WhatsApp: +86 18838072829In traditional slotting, we may drive a ½" tool down 2xD into the part to make a full slot, and the tool can handle it! But this technique simply isn't possible with a smaller tool. For example, let's take a .015" end mill. If we are making a slot that is .015" deep with that tool, we are likely going to take a .001" to .002 ...

With better heat and wear resistance than highspeed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
WhatsApp: +86 18838072829Ball Nose Mills have a radius, a hemisphere, or half of a ball (which is where it gets its name from) to give it a rounded end instead. Now there is a type of tool that lies somewhere between these two, which can be called a Bull Nose Mill or a Tip Radius End Mill, which has a partly flat bottom with a radius just around the edges.
