Product description
- PFERD diamond needle file knife 140mm D126 (medium) for hard materials
Characteristics
- Diamond files and sheets are used for tasks where conventional files fail due to the hardness of the material being worked on

- The working temperatures are so low that no chemical wear occurs
- This allows the higher hardness of the diamond grain to be exploited for a longer tool life
- Diamond needle files can be used generally in tool making
