Woodworking Light-Duty Spiral Planer Blades

What Is a Light-Duty Helical Spiral Cutter Head?

A light-duty spiral cutterhead is a precision-engineered woodworking cutter head designed for light cutting operations.
Unlike traditional straight knife cutterheads, this design uses spiral planer blades arranged helically around the cutter body.

Structural Components

A typical helical cutterhead for wood consists of:

• High-strength alloy steel spiral cutter body

• Precision-machined spiral grooves

• Indexable tungsten carbide inserts

• Countersunk screws for secure blade positioning

Each insert sits at a slight angle, allowing the cutter to shear the wood fibers instead of chopping them directly.
