Frequently Asked Questions (FAQs)

1. What is a square end mill?

Square end milling cutters are also known as a "flat end mills". The corners of these mills are sharp and generate a 90° angle. They can be single end or double end and they can be made from solid carbide or various compositions of high speed steel.

2. What are the most common end mill nose geometries?

The most common profile styles for end mills are square, corner radius, and ball. The square profile on an end mill has flutes with sharp corners that are squared off at 90°.

3. What is a bull nose end mill?

Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder.

4. What does bull nose end mills have on the corners?

Corner Radius End Mills This type of tooling breaks up a sharp corner with a radius form. This rounding helps distribute cutting forces more evenly across the corner, helping to prevent wear or chipping while prolonging functional tool life. A tool with larger radii can also be referred to as “bull nose.”
