Frequently Asked Questions (FAQs)

1. What is the purpose of a ball nose end mill?

The purpose of a ball nose end mill is to drill shallow holes, create slots where a flat bottom is not required, or produce multi-dimensional contours in molds or dies. The design of ball end mills allows for a hemispherical cutting action, matching the tool's diameter.

2. What is the advantage of using bull nose end mills?

Bull nose end mills offer more robust milling edges compared to square end mills. This allows for increased feed rates, leading to longer tool life and improved productivity. Bull nose end mills are commonly used in mold profiling applications, providing greater productivity compared to bell end mills.

3. Can you plunge with a ball end mill?

While it is possible to plunge with a ball nose end mill, it is generally recommended to avoid it. If plunging is necessary, it is best to ramp down by moving along the X and/or Y axis at a shallow angle, typically less than 3 degrees.

4. Can you plunge with an end mill?

Centre-cutting end mills are capable of plunging straight down into the material. These end mills have cutting edges on the end face and the sides, allowing them to both mill and drill. Typically, 2 or 3 flute end mills are center-cutting, although some 4 flute end mills may also have this capability.

5. Can you plunge with a flat end mill?

Flat end mills, also known as square-end mills, are suitable for general milling applications including slotting, profiling, and plunge cutting. They produce a sharp edge at the bottom of slots and pockets in the workpiece.
