Q20 Pos.1-8 Resin Metal Bonded Diamond Router Bit for Granite Marble CNC Profiling & Polishing

 

Product Description:

The Q20 Pos.1-8 is a Hybrid Diamond Router Bit for CNC machining of natural stones (granite, marble) and concrete. Its resin-metal bonded matrix optimizes durability and cutting precision, supporting both segmented (fast material removal) and continuous (fine finishing) edge profiles. Perfect for fabricators needing adaptability across roughing and finishing stages.

Diamond Router Bit

It features three segment types—metal segmented (for rough grinding), metal continuous, and resin bond continuous.

 

Technical Specifications:

  • Bond Type: Resin-metal hybrid (combines resin’s smoothness with metal’s heat resistance)
  • Edge Types: Segmented (aggressive profiling) + Continuous (smooth polishing)
  • Material Compatibility: Granite, marble, concrete, engineered stone (soft to hard)
  • Primary Use: CNC profiling, edge polishing, and detail work
  • Compatibility: CNC routers (check collet size for 5/8"-11 or M14 arbor)
  • Speed Range: 8,000–15,000 RPM (adjust based on stone hardness)

Technical Specifications

Key Selling Points​

  • Hybrid Bond Advantage: Resin-metal bonding resists wear from hard stones (e.g., granite) while minimizing heat buildup—extending tool life and maintaining sharpness.
  • Dual Edge Flexibility: Switch between segmented edges for rapid stock removal (e.g., shaping raw slabs) and continuous edges for polished finishes (e.g., final countertop edges).
  • CNC-Optimized Design: Precision-machined geometry ensures stable performance at high speeds, reducing vibration and achieving tight tolerances (±0.05mm) for smooth, consistent edges.
  • ​Multi-Stage Efficiency: Eliminates the need for multiple bits—handles roughing, profiling, and polishing in one workflow, saving time and reducing tool changes.

 

Applications:

  • Countertop Fabrication: Shaping and polishing granite/marble kitchen/bathroom tops (from rough slabs to finished edges).
  • Decorative Stone Work: Profiling fireplace surrounds, wall cladding, and sculptural elements with both bold (segmented) and elegant (continuous) edges.
  • Commercial Projects: Producing uniform edges for hotel lobbies, restaurant tables, or retail displays requiring high precision.
  • Restoration & Repair: Refacing worn stone edges with minimal material loss, using continuous edges for seamless finishing.

Applications

FAQ - Frequently Asked Questions:

Q: When should I use segmented vs. continuous edges?

A: Use segmented edges for rapid material removal (e.g., rough-shaping thick slabs) and continuous edges for final polishing (e.g., smoothing visible countertop edges).

Q: Does this bit work on soft stones like limestone?

A: Yes—resin-metal bonding adapts to soft stones, but reduce speed (8,000–10,000 RPM) to avoid excessive wear on the resin matrix.

Q: Is special maintenance required for the hybrid bond?

A: Clean with compressed air post-use to remove stone dust; avoid water immersion (resin is water-resistant but not waterproof). Store in a cool, dry place.

Q: What CNC routers are compatible?

A: It fits most standard CNC routers with 5/8"-11 or M14 collets. Confirm arbor size with your router manual for optimal performance.
