They also have high heat resistance and are best suited for working with the most rigid material, even at high speed. Tungsten Carbide End Mills: They are more expensive than HSS but offer more toughness and resistance to wear and tear conditions.High-Speed Steel (HSS) End Mills: They ate relatively cheaper than solid carbide but have reduced speed capabilities and a little low life span.End Mills Type: Classification Based on MaterialĮnd mills are often manufactured with either cobalt steel alloys (High-Speed Steel) or tungsten carbide.

Also, they are the more common types of end mills used in machine shops. 4 Flute End Mills are best suited for cutting workpieces that are considered too hard to work with 2 flute cutters.3 Flute End Mills have good chip removal and average resistance to wear and tear.2 Flute End Mills are ideal for aluminum and wood because they are softer and produce larger chips.Therefore, manufacturers may need to consider the material they are working on before deciding the kind of end mill to use for their fabrication. However, reduced flutes denote better chip clearance and reduced heat build-up. Typically, end mills have 2, 3, or 4 flute configurations, though the 3 flutes end mills are less common than the other two.Īn increase in the number of flutes will cause an increased feed rate of the cutters and the production of cuts with better surface finish.

The flutes are the spiral grooves on the cutting edge of end mills that allow chip formation removal during cutting. It reduces the splintering of the workpieces and is suitable for making pockets with flat bottoms, plunge routing, precise contours, etc.Įnd Mills Type: Classification by Number of Flutes

Fishtail end mills: These mills have cutting teeth focused on one end, which is usually flat so that it can cut through any material, including thin sheets.

They are suitable for milling contoured surfaces, shallow slotting, etc.

Ball end mills: These mills have a rounded cutting edge, which gives the workpiece an improved surface finish.

They serve as general-purpose end mills used in face milling, side milling, etc. These mills have a sharp square corner, which makes them suitable for 90° cuts in the workpiece.

Square-end mills: They are also known as flat-end mills.

They are also used in lettering, engraving intricate details, and making signs. This makes them suitable for making narrow and small cuts.

V-bits: The cutting teeth are of small angles, usually 60° or 90° forming a V-shaped cutting end.

Let’s examine different types of end mills under this classification.īased on the shape of the shapes, end mills can be further classified into the following. End mills are categorized based on the shape, number of flutes, material type, etc.
