Frequently Asked Questions (FAQs)

1. What is a 4 flute end mill used for?

A 4 flute end mill is commonly used for machining steel and harder alloys. It provides better performance and efficiency in these materials compared to a 2 flute end mill.

2. How do I know what end mill to use?

When selecting an end mill, consider the length of cut needed for the operation. It should be only as long as necessary and no longer. Choosing the shortest tool possible reduces overhang, improves rigidity, and minimizes chatter during machining.

3. Why do designers use rounded corners?

Designers use rounded corners because they make information easier to process. Sharp corners can disrupt the flow of the eye along a line, causing abrupt pauses. Rounded corners guide the eye smoothly around each corner, maintaining a continuous path.

4. What is a corner rounder used for?

A corner rounder, also known as a corner rounder cutter, is used to add rounded corners to documents, covers, business cards, and other printed materials. It helps create a visually appealing rounded radius on the edges.

5. What is the benefit of corner radius end mill?

A corner radius end mill breaks up sharp corners with a rounded form. This distributes cutting forces more evenly, reducing wear or chipping and prolonging tool life. Larger radii versions are sometimes referred to as 'bull nose' end mills.

6. What is a 5 flute end mill used for?

A 5 flute chipbreaker end mill is designed for exceptional metal removal on steels and stainless steels. It offers high performance and efficiency in these materials.

7. What is a 6 flute end mill used for?

A 6 flute end mill is used for finishing operations that require good surface finishes and higher feed rates. They are not suitable for rough milling due to their lower flute volume.
