Partial Profile
INTRODUCTION

Tools belonging to this group do not produce the outer diameter (major diameter) of external
threads or the inner diameter (minor diameter) of internal threads, which means that one or
more additional operations are needed to complete the thread diameter. These tools are not
recommended for mass production.

Advantages of Partial Profile Tools
• Small corner radius, suitable for many pitch sizes
• Reduces stock of many different full profiled inserts

Disadvantages of Partial Profile Tools
• Small corner radius will result in shorter tool life

• Requires additional operation/s to the complete the outer (major) or inner (minor) diameter,
depending on the thread gender
