6×22 GT Single Flute Up Down Cut Spiral Bit Guide
The 6×22 GT Single Flute Up Down Cut Spiral Bit from JEEFOO in Guangzhou, China combines up-cut and down-cut action so the cutting forces press toward the center of a panel. This geometry helps protect both visible faces when routing laminated board, plywood, MDF, acrylic, PVC, cork and compatible wood or plastic panels.
Specifications and geometry
- Cutting diameter: 6 mm
- Cutting length: 22 mm
- Series: GT solid carbide
- Geometry: single-flute up-and-down compression spiral
- Typical equipment: CNC routers and engraving machines
When compression geometry works best
A compression bit performs best when the workpiece is thick enough for both the up-cut and down-cut sections to engage. The first pass must reach beyond the short up-cut section; otherwise the top face may not receive the intended downward cutting action. Verify the transition length, sheet thickness and programmed depth before production.
Recommended CNC applications
- Through-cutting laminated plywood and double-sided panels
- Profiling MDF, solid wood and furniture components
- Cutting acrylic, PVC and composite plastic boards after a parameter test
- Sign making and nested-based CNC routing where both faces must remain clean
Machine setup and chip control
Clean the collet and shank, minimize overhang and secure the panel on a flat spoilboard. Confirm that vacuum or mechanical workholding can resist the toolpath forces. Start with conservative spindle speed, feed rate and depth per pass, then adjust gradually while observing chip size, sound, spindle load and edge quality.
Remove chips continuously with dust extraction or an air system approved for the machine and material. Recutting chips increases heat and can mark acrylic or laminate surfaces. Use a sharp tool and stop if vibration, burning, melting, edge breakout or abnormal spindle load appears.

Frequently asked questions
What does 6×22 mean?
It identifies a 6 mm cutting diameter and a 22 mm cutting length.
Why use a compression bit on laminated panels?
The opposing flute directions help reduce chipping on both the top and bottom faces during through cuts.
Can JEEFOO recommend a custom tool?
Yes. Provide the panel material, thickness, machine, shank requirement and quantity for review.
6×22 GT Single Flute Up Down Cut Spiral Bit is a solid carbide single-flute compression cutter designed for clean CNC routing on acrylic, PVC, cork, MDF, plywood, solid wood, mahogany and other plastic or wood panels.
One Spiral Flute Up&Down Cut Compression Router Bits and CNC cutting tools
6×22 GT Single Flute Up Down Cut Spiral Bit Product Description
This single-blade composite cutter combines up-cut and down-cut spiral geometry. The opposing cutting forces compress the top and bottom surfaces toward the center of the workpiece, helping reduce burrs, edge lifting and chipping. It is suitable for CNC routers and engraving machines used for signage, cabinetry, plastic fabrication and woodworking.
Material: whole solid tungsten carbide. Imported carbide options are available for stable cutting performance and long service life.
Suitable materials: PVC, acrylic, resin, hibiscus board, cork, MDF, plywood, solid wood, mahogany and hardwood.
Size: 6×22
Clean Up and Down Spiral CNC Cutting
The 6×22 GT Single Flute Up Down Cut Spiral Bit uses one polished flute for efficient chip evacuation while the compression profile protects both faces of laminated and brittle sheet material. Use the correct spindle speed, feed rate and clamping method for the material. A rigid CNC setup and suitable dust extraction help maintain a smooth finish and consistent tool life.
