- II. Internal thread workpiece material × Threading-Taps material
- The material of the threading tool is not the only determining factor.
The material of the threading tool is not the only determining factor.
UGMIC Special Reminder:
The statement "Tungsten steel is always better than high-speed steel" is not a complete logic for threading tool selection.
Tool material is only one factor in the threading system.
Actual tool life and machining quality are primarily influenced by:
• Tool material
• Tool heat treatment
• Tool manufacturing process
• Tool geometry
• Helix angle
• Groove design
• Chip breaking capability
• Chip removal capability
• Workpiece material
• Workpiece hardness
• Hole type
• Thread depth
• Spindle runout
• Tool holder runout
• Cooling and lubrication
• Machine condition
Therefore, material selection should focus on the "tool × workpiece" match, rather than simply pursuing the highest hardness.
