Ball 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.

WhatsApp: +86 18838072829Bullnose End Mill. You can see bullnose end mills as a transition between flat and ballnose ones. The radius of its round corner is smaller than the cutting radius. Since they combine a flat bottom with round corners, they can create flatbottomed pockets with rounded corners at once without changing tools. Bullnose end mill. Roughing End Mill
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 ...
