Bull-Nose Corner Radius End Mill.

Sometimes called bull-nose end mills they are rotated against a workpiece to create a flat-bottomed groove with slightly rounded inside corners in milling applications that require a specific radius. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. This type of tooling features flutes with no flat bottom rounded off at the end creating a ball nose at the tip of the tool.

Ball end mills also known as ball nose end mills are used for milling contoured surfaces slotting and pocketing. Bull end mills are simply corner radius end mill cutters. EXISTSSELFedge_radius AND EXISTSSELFeffective_cutting_diameter AND SELFedge_radius SELFeffective_cutting_diameter2.

These have a flat bottom but rounded corners so you can have a filleted inner corner while also. Also called corner radius end mills this type of cutter is a combination of fishtail and ball-nose also a flat bottom but with rounded corners. In the meantime tbaker the only compromise is to define it as a bullnose with the chord length of the bull radius matching the chamfer length.

When using a ball nose end mill the most critical area of the cutting edge is the tool centre where the cutting speed is close to zero which is unfavourable for the cutting process.

Ball nose end mills or ball end cutters are constructed with a round cutting end and center cutting edges used for milling contoured surfaces slotting and pocketing. Roughing end mills also known as hog mills are used to quickly remove large amounts of material during heavier operations.

Ball nose mills have a radius at the bottom which makes for a nicer surface finish in your workpiece meaning less work for you as the piece wont need to be finished any further.

The words end mill are generally used to refer to flat bottomed cutters but also include rounded cutters referred to as ball nosed and radiused cutters referred to as bull nose or torus.

Chip evacuation at the tool centre is critical due to the narrow space at the chisel edge. They are the most common tool used in a vertical mill. Made of solid carbide theyre harder stronger and more wear resistant than high-speed steel for the longest life and best finish on hard material.

Ball end cutters are usually made from carbide steel or other high-speed steel composition. Additionally a smaller diameter ball nose mill can also be used in engraving. Corner radius end mill cutters have a stronger milling edge than square end mills so feed rates may be increased and yield longer tool life and greater productivity.

The cutter diameter is often the first thing machinists look for when choosing a tool for their job. Choosing flat end mill vs.
