Frequently Asked Questions (FAQs)
1. What is a square end mill used for?
Square end mills are commonly used for general milling applications such as slotting, profiling, and plunge cutting. They are designed to create a sharp edge at the bottom of slots and pockets in the workpiece.
2. What are ball nose end mills for?
Ball nose end mills are versatile tools used for a variety of milling operations, including contouring, profiling, slotting, and corner picking. They are particularly effective in 3D semi-finishing and finishing operations, especially in industries like Mold & Die, where their shape allows for efficient machining of part contours.
3. Can you drill with a square end mill?
While it is possible to drill with a square end mill using short pecks, it is generally recommended to use a helical path or predrill a hole for better results. When creating a pocket, it is best to predrill a hole or use a ramping technique to avoid tool damage.
4. Can you plunge with an end mill?
Yes, certain end mills known as center-cutting end mills are designed for plunging straight down into the material. These end mills have cutting edges on the end face and the sides, typically with 2 or 3 flutes. Some 4-flute end mills can also be center-cutting.
5. What is the difference between a slot cutter and an end mill?
A slot cutter is a combination of a drill and an end mill, allowing it to plunge like a drill and then slot across like an end mill. On the other hand, an end mill primarily cuts laterally and horizontally. Slot drills have a flute that comes to the middle, while end mills have clearance in the center.
6. Can you plunge with a flat end mill?
Yes, flat end mills, also known as square-end mills, can be used for plunging. They are commonly used 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.
