Solid carbide finishing spiral tooling is designed for CNC routing applications where clean edge quality and a consistent finish are required. Prima Tooling supplies and manufactures finishing spirals for natural woods, wood composites and a range of routing applications.

Available in upcut and downcut geometries, solid carbide finishing spirals can be selected according to the required surface finish, cutting direction and chip removal.

Upcut and Downcut Finishing Spirals

Upcut finishing spirals direct chips upwards and away from the cutting area while providing a clean finish to the lower edge of the workpiece.

Downcut finishing spirals provide a downward shearing action and are useful where maintaining a clean top edge is important, including groove, dado and through-cut applications.

Tool selection should take account of the material, required edge quality, cutting direction and machining operation.

Two and Three Flute Finishing Spirals

Two-flute solid carbide finishing spirals provide a versatile solution for general CNC routing applications.

Where an exceptionally smooth edge is required, three-flute finishing spirals can provide an improved finish at the same feed rate and may also provide increased tool life compared with a two-flute design.

Three-flute finishing spirals are particularly suited to natural woods and wood composites.
