1. Pitch (wave density)
Coarse teeth (fewer teeth): With a larger chip space, it is more suitable for processing soft and viscous materials such as aluminum, copper, and cork, and has better chip removal performance.
Fine teeth (with more teeth): Cutting is smoother and suitable for processing hard materials such as steel, cast iron, and hard titanium alloys.
2. Material and Coating
Solid hard alloy: suitable for high-speed machining of most CNC machine tools, especially for high hardness materials.
Powder high-speed steel (HSS-E/PM): It has better toughness, relatively cheaper price, and is suitable for some heavy-duty or machine tool impact situations.
Coating: High temperature resistant coatings such as TiAlN or AlCrN are almost standard, which can significantly improve the red hardness and wear resistance of cutting tools, suitable for high-speed dry cutting or deep cutting.
3. Corner radius
Many rough skin milling cutters are also designed with a Bull Nose style bottom edge, which has a rounded corner. This further enhances the strength of the cutting edge and prevents chipping during heavy cutting.
