4" PCD Spoilboard Cutter - Up Cut 3/4"Shank - 4 Wing

These tools create a wide, shallow cut on the face of the workpiece. They're often used to level spoilboard so it lies perfectly flat for accurate routing and milling. When the cutting edges dull, replace the carbide inserts rather than replacing the entire tool.

These large CNC Surfacing bits are designed to resurface your workpiece or CNC spoilboard. The bit has a straight cut and extended life through the use of replaceable carbide inserts.

Materials: Natural woods, composite woods, hard plastics

Recommended RPM: 10,000-12,000 (max 12,000)
