Benefi ts of thread milling vs. tapping
When deciding on the choice of threading method, the benefi ts of
thread milling over thread tapping should be considered.
Tooling inventory
• Standard tool holders
• One thread mill tool covers different diameters
• Same thread milling insert for left- and right-hand threads
• Different pitches possible with one insert
Tool breakage
• Easier to remove a broken tool from the component
• Maximum production security
• Reduced machine downtime
• Ideal for diffi cult materials
• First choice for expensive components/last stage machining
Chip control
• Better chip control, fewer machining stoppages
• Benefi cial method in long-chipping materials
