Technical guidance & FAQs

Applications and materials

These metric Harvey Tool square end mills target hardened tool, die and mold steels up to 55 HRC. Five-flute variable-helix geometry supports hard-steel slotting and roughing, with AlTiN Nano coating for hardness and heat resistance. The family also covers manufacturer-listed stainless and high-temperature-alloy applications.

Choosing a configuration

Choose the metric cutter diameter and length of cut, then check the separate shank dimension and overall length. Confirm workpiece hardness before selecting this family instead of the harder-steel seven-flute range.

Compatibility and use

Use the exact metric tool number and its mapped running-data sheet. The larger shank supports rigidity but needs the correct holder bore. Center-cutting geometry does not remove the need for operation-specific feed and entry guidance.

Which hardness range applies?

This is the up-to-55-HRC family for hardened tool, die and mold steels. Use a separately specified design for harder material.

Does this family have five or seven flutes?

It has five flutes and center-cutting geometry. The separate 45–68-HRC square family uses seven flutes.

What dimensions need checking for the holder?

Use the listed shank diameter and engagement requirements, not cutter diameter alone. Also verify overall length and the required projection.
