The metal cutting tool edge is the part of the tool that contacts and removes the material being processed. Its shape, size and material directly affect the efficiency of the 

cutting process and the quality of the machined surface.

What are the types of metal cutting tool edges?

Metal cutting tools can be divided into several types based on their use and design, including but not limited to:

Straight edge tools: Suitable for straight cutting, commonly used for milling and flat cutting.

Spiral edge tools: Improve cutting efficiency through spiral edges, commonly seen in drills and milling cutters.

Forming tools: Used to process workpieces of specific shapes, such as gear cutters and form milling cutters.

Compound edge tools: Tools that combine multiple cutting modes for specific processing tasks.

How to choose the right metal cutting tool edge?

Choosing the right tool edge requires considering the following factors:

Material being processed: Different materials require different types of tool edges due to their hardness and toughness.

Type of processing: Roughing, finishing or other special processing methods will affect tool selection.

Processing conditions: Include cutting speed, feed rate and cutting depth.

Machine tool capacity: The power and stability of the machine tool will also limit tool selection
