Machining operation: 
a. Side face: Flattened end mills for side machining
b. Step shoulder: Flattened end mills for shoulder machining
c. Straight slot: Flattened end mills for deep slot machining
Applicable workpiece material:
1. Very suitable for carbon steel , alloy steel, Pre-hardened steel ,hardened steel with 40HRC/50HRC/55HRC, cast iron, nodular cast iron
2. Suitable for stainless steel, Tianium alloy, heat resistant alloy
Advantage of high-performance general machining end mills
1. Optimized geometry, improves chip removal and chip forming with reduced cutting force.
2. Higher feed rates and improved metal removal rate for efficient machining, due to high stability of cutting edge and rigid tool structure.

End mills series of sharp and corner protection type
The characteristic of corner protection end mill:
1) It's suitable for bad cutting condition or hardness material machining.
2) High cutting edge strength and breakage resistance.
3) The degree of nose sharpness is reduced, the vestiage is left.
The characteristic of sharp end mill:
1) True 90 degree angle is obtained without material remaining in the corner.
2) The corner part is sharp, it is applicable in finishing or soft material machining. Especially, it is usually used in machining of non-ferrous material such as AI.
