To be used only on CNC machines and routers with automatic feeding. Solid carbide Spiral 'O' flute Up-Cut plastic cutting CNC router bits use the highest quality sub-micrograin carbide, have a special proprietary edge processing system and feature a super high polished cutting edge with a unique “mirror finish”, resulting in clean cuts, superior surface finish and a longer tool life. The Spiral ‘O’ flute sharpening/finishing process increases feed rates, allowing for more linear feet routed in less time.These bits are specifically designed for a variety CNC machining applications and a long list (see below) of materials. Continuous improvements in cutting performance, the unique carbide polishing process, tool design & geometry make these router bits perfect for routing signs and displays. Signmaking (signcrafter) router bits were originally developed in Europe specifically for professional sign makers. Corrugated plastic products, such as Correx boards are used in a variety of applications including boat building, packaging, signage, outdoor advertising, and the production of pet cages. Today, CNC routers have become the tool of choice for sign makers, moving beyond printers and vinyl cutters.
Benefits of Mirror-Finish:
- Industrial quality
- Single flute design
- Super high flute mirror finish results in better cut quality
- Dissipates heat well and prevents melting
- Right hand helix/right hand cut
- Eject chips up or down

Questions & Answers
Popular Questions
A compression bit features both up-cut and down-cut flutes, pulling material fibers toward the center to achieve clean, splinter-free edges on both faces—perfect for plywood and laminates. Conversely, a down-cut bit pushes chips downward, yielding a smooth top surface but often leaving rough or torn bottom edges. The primary distinction is how each bit directs chips and fibers, directly affecting the finish quality of the cut edges, especially on double-sided or veneered materials.
A compression router bit is best used when cutting plywood, laminates, or veneered boards to prevent tear-out on both the top and bottom surfaces. By combining up-cut and down-cut flutes, it effectively pulls fibers toward the center, ensuring exceptionally clean, chip-free edges on both sides of the material in a single pass.
