What’s the difference between flat end mill, ball nose end mill, corner radius end mill?
An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills. End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging. -from wikipediaOur’s end mill can be divided into HRC45 HRC55 HRC65, etc. According to coating, it can be divided into uncoated, AlTiN, TiSiN, AlTiSiN, DLC coating, diamond coating end mills, etc. In addition, we can also divide the endmills into a flat, ball nose, and corner radius cutter. What’s the difference between these types? As a professional manufacturer of solid carbide end mill, Our tells you.
Flat End Mill
Flat end mill is the most popular end mill for our customers, of which 2-flute, 3-flute, 4-flute, and 6-flute are very common. The less the flute number, the smoother the chip removal, and the more the flute number, the more precise the processing, the commonly used flat end milling cutter models are:
- 1/4″ 2-flute flat end mill
- 1/8″ 2-flute flat end mill
- 1/16″ 2-flute flat end mill
- 1/32″ 2-flute flat end mill
- 1/64″ 2-flute flat end mill
- 1/100″ 2-flute flat end mil
The flat end mill is widely used in groove processing, side processing, and step surface processing.
Ball Nose End Mill
Ball nose end mill is a kind of tool which is assembled on the milling machine with the cutter similar to the ball head and is used for milling various curved surfaces and arc grooves.
The ball nose end mill has the best effect on the machining curved surface, but the chip discharge performance is poor because of the small chip holding groove at the tip.
Corner Radius End Mill
Corner radius end mill is used for machining the corner R and periodic feeding. In periodic feed machining, even if R is small, it can also be used for end mills with a large diameter for efficient machining.
When the workpiece is large, the narrow concave area is less, the surface change is small, the relatively flat area is suitable for the corner radius end mill, and the narrow concave area is suitable for the ball nose end mill.
| Item | Flat End Mill | Ball Nose End Mill | Corner Radius End Mill |
| Shape | Square | Round | Square with a corner rounding |
| Common Flute Numbers | 2/3/4/6 Flutes | 2/4 Flutes | 2/3/4 Flutes |
| Application | Groove processing, side processing, and step surface processing | Milling various curved surfaces and arc grooves | High speed machining, round sharp corners |
Whatever end mills or Carbide inserts, customers often purchase the most general grade. In fact, according to the performance of processing products and parameters of the CNC machine, selecting the most suitable products can greatly improve the production efficiency. In addition, Our can provide product customization services.
