Frequently asked questions
What dimensions are listed in the HF/HZ reference tables?
The page presents separate HF and HZ dimensional references in millimetres. Select the table and row matching the identified insert family.
Can dimensions alone establish a replacement across HF and HZ?
Use dimensions together with the reference code, spindle arrangement and application. Similar measurements do not identify every feature of an assembly.
