Description

Zund Milling & Router Bits R71(3910752)

The Zund R71 CNC milling and router bit (Part Number: 3910752) is a micro-milling solid carbide tool engineered for high-precision, fine-detail cutting tasks on Zund digital cutters. It shares identical dimensional specifications with the Zund R44 but belongs to a different production series optimized for highly efficient chip extraction on softer and multi-layered substrates.

Technical Specifications

Cutting Direction: Right-hand twist (Up-cut / Right-hand spiral). It pulls material chips up and out of the cut furrow, funneling them straight into the machine's vacuum extraction kit.
Design Geometry: Single-flute (O-flute) polished execution for high-velocity chip clearance and minimized heat friction.
Dimensions: 1mm routing diameter with a 4mm maximum cutting depth and a total length of 30mm.
Shank Diameter: 3mm.
Max Rotational Speed: Rated up to 80,000 RPM.

Recommended Applications

The R71’s ultra-thin 1mm cutting profile is built specifically for intricate contours, sharp filigree radius cuts, micro-engraving, and tight channel milling across a variety of flexible and rigid substrates:

Aluminium Composite Materials (ACM / Dibond)
Plastics & Polymers (Acrylic, Polypropylene, PA 6.6, PET, Polycarbonate)
Wood Composites (MDF, MPX, Plywood)
Foams & Signs (Expanded PVC / Forex, PUR foam, PE foam, XPS)

Tool & Cutter Compatibility

This bit fits perfectly into the Universal Routing Tool (URT), Router Module RM-A, and RM-L systems. It integrates natively across Zund’s signature G3, S3, L3, and D3 industrial flatbed cutting tables.
