Technical guidance & FAQs

Applications and materials

Harvey Tool single-flute downcut end mills are intended for plastic slotting and roughing when the top edge needs protection from fraying and chipout. The downcut design also limits workpiece lifting on vacuum tables. Hard-plastic, soft-plastic and hard-plastic Amorphous Diamond configurations are separate choices.

Choosing a configuration

Match the plastic type first, then choose cutter diameter, flute length and shank size. Consider how chips will leave the feature when choosing a downcut tool rather than an upcut design.

Compatibility and use

A left-hand spiral does not mean reverse spindle rotation: this family is right-hand cutting. Use the specific geometry’s running data and confirm the workholding and chip-clearing strategy suit the part.

When is a downcut useful in plastics?

Harvey recommends it to reduce top-edge fraying and chipout and to prevent lifting on vacuum tables.

Does left-hand spiral mean left-hand cutting?

No. These tools have a left-hand spiral and right-hand cut. Spiral direction and cutting direction describe different features.

Can I choose one geometry for every plastic?

Choose the hard- or soft-plastic configuration specified by Harvey. Coating and cutting conditions should suit the particular material.
