Technical guidance & FAQs

Applications and materials

These metric Harvey Tool variable-helix square end mills target aluminum-alloy slotting, plunging and roughing. The three-flute, center-cutting carbide design helps reduce chatter and harmonics. Harvey also identifies copper, brass and bronze alloys as applications for this family.

Choosing a configuration

Select the metric cutter diameter and cutting length, then match the metric shank and overall length to the holder and available clearance. Compare coating options by exact tool number; not every inch configuration has a corresponding metric version.

Compatibility and use

Use the selected metric dimensions and its matching manufacturer running-data sheet. The h6 shank tolerance supports precision holder fit, but the holder’s specified bore and clamping requirements still need to match. Choose coating and cutting conditions for the particular non-ferrous alloy.

What is the benefit of the variable helix?

The manufacturer uses it to reduce chatter and harmonics during aluminum-alloy machining. This family has three flutes and a square, center-cutting profile.

Which non-ferrous alloys are listed?

Aluminum and aluminum alloys are the primary application; Harvey also lists copper, brass and bronze alloys. Confirm the chosen coating and cutting data for the actual alloy.

Are the metric and inch listings interchangeable?

They share the family design, but tool numbers and dimensional combinations differ. Match the metric cutting and shank dimensions to the application rather than rounding an inch size.
