Zund Milling & Router Bits R40(3910730)

Zund R40 Tungsten Carbide Router Bit (Part Number: 3910730) is a specialized, single-flute up-cut spiral milling bit designed for high-precision, high-speed digital cutting systems. Engineered from solid tungsten carbide, this specific tool offers extreme wear resistance and is highly effective at maintaining smooth finishes on non-ferrous and dense substrates.


Key Specifications
  • Routing Diameter: 1.0 mm
  • Shank Diameter: 3.0 mm
  • Max Routing Depth: 4.0 mm
  • Number of Flutes: 1 (Single-flute, right-hand up-cut spiral)
  • Maximum Rotation Speed: 80,000 RPM 

Recommended Materials
The R40 bit is optimized to prevent melting, chipping, or burring on specific tough and abrasive materials, including:
  • Acrylic (PMMA)
  • Aluminum sheet and composite panels
  • Polycarbonate
  • Other rigid plastics (such as Dibond and dense PVC) 

Operational Geometry
Because it utilizes a single-flute up-cut spiral design, the tool provides exceptional chip clearance. At high spindle speeds up to 80,000 RPM, it rapidly pulls waste material upward away from the cutting track. This prevents heat build-up and ensures clean, burr-free edge qualities on thin sheet stocks under 4mm deep.
