Solid Carbide Two-Flute Compression Router Bit for Woodworking Production
This solid carbide compression router bit combines opposing spiral cutting sections for routing panel materials, offered in cutting diameters from 1 to 12 mm with matching cutting lengths and shanks. Two flutes clear chips in both directions of the compression cut.
Design and Construction
＋The lower section shears upward and the upper section shears downward, pressing fibres toward the panel core — the compression geometry that keeps both faces clean in one pass. The chart lists cutting diameters 1–12 mm, cutting lengths 4–42 mm, shank diameters 3.175, 4, 6 and 8 mm and overall lengths 38–75 mm as complete configurations. The series is produced in the Sichuan and Dongguan, China manufacturing bases.
How It Works
＋In the CNC router the bit plunges and traces the nesting path at full panel depth: the up-shear section holds the bottom veneer while the down-shear section holds the top coating. The two flutes evacuate chips from both directions, and the solid-carbide body keeps the compression transition stable through long nesting runs.
Applications
- Compression (up-down shear) routing of nested panels on CNC routers, engraving machines and precision engraving equipment
- Through-cutting veneered board, plywood, MDF, particleboard and selected plastic boards including PVC
Suitable Materials
- Veneered board, plywood, MDF, particleboard and selected plastics including PVC, subject to grade and application review
- Suitability depends on the specific material grade, panel thickness and machining parameters; confirm the application before ordering
Material Comparison: High-Speed Steel (HSS) Tool vs. Solid Carbide Tool
＋Typical industry data for reference. Actual results depend on the workpiece grade, machine condition and feed rate.

Delivery Scope
Select a complete table row — dimensions from different rows are not combined. The gallery shows silver-finish cutters and a coated option; confirm the finish when ordering (the coating chemistry is not specified).
＋Each order also includes an inspection record. Send the panel type and thickness, required cutting diameter and cutting length, collet/shank size, CNC machine model and cutting operation, and confirm the compression transition point for through-cutting.
Why Choose VPOINT
＋VPOINT supports this carbide tool series with:
- One-year warranty on every tool
- Custom diameters, shanks and rotations produced to order
- Regrinding service to extend tool life
- Factory direct since 2008, ISO 9001 certified

Frequently Asked Questions
Which diameters and shanks are listed?
＋The chart lists cutting diameters from 1 to 12 mm, cutting lengths from 4 to 42 mm, shank diameters of 3.175, 4, 6 and 8 mm and overall lengths from 38 to 75 mm, as complete configurations.
Can rows be mixed?
＋No. Each table row is one complete configuration; dimensions from different rows are not combined.
What panel thickness suits compression routing?
＋The compression transition point must sit within the panel thickness. Send the panel type and thickness so the cutting length and transition are confirmed for through-cutting.
What should I send for a quotation?
＋Panel type and thickness, required cutting diameter and cutting length, collet/shank size, CNC machine model and cutting operation, plus the finish (silver or coated).
