Technical guidance & FAQs

Applications and materials

Harvey Tool seven-flute square end mills are designed for hardened steels from 45 to 68 HRC, including hardened stainless, tool and mold steels. Variable-helix geometry addresses material removal in hard milling, while AlTiN Nano coating provides hardness and heat resistance.

Choosing a configuration

Confirm actual workpiece hardness, then choose cutter diameter and cutting length for the feature. Check shank diameter, holder fit and tool projection; the manufacturer specifies an h6 shank tolerance.

Compatibility and use

This family is end cutting but not center cutting. Do not assume it can perform a straight center plunge like a center-cutting end mill. Use the exact tool’s hard-milling guidance and an entry method appropriate to its geometry.

Choose the speeds and feeds sheet for your exact tool number and coating; the linked sheets cover different configurations in this family.

What hardness range is this family designed for?

Harvey specifies hardened steels between 45 and 68 HRC, including tool and mold steels.

Is this seven-flute tool center cutting?

No. The manufacturer explicitly describes it as end cutting, not center cutting. Plan the entry path accordingly.

How does it differ from the up-to-55-HRC family?

This range has seven flutes and a different hard-milling geometry. The up-to-55-HRC square family has five flutes and is center cutting.
