Description

Zund With Stop Ring Router Bits R219-A(5211734)

Zund R219-A (Zund official Item No. 5211734) is a premium, solid tungsten carbide 2-flute spiral router bit explicitly engineered for Zund digital flatbed cutting systems. The critical "-A" designation denotes that the tool comes pre-fitted with a precision-integrated stop ring / retaining ring. This ring acts as a mechanical spacer required for automated Z-axis initialization and tool depth calibration within the machine's software.

Key Technical Specifications

Routing Diameter: 6.00 mm.
Shank Diameter: 6.00 mm straight shank.
Maximum Routing Depth: 40.00 mm (extended deep-reach geometry).
Overall Tool Length: 85.00 mm.
Flute Configuration: 2 cutting edges (2-fluted) with a right-hand upcut twist.
Maximum Rotation Speed: 48,000 RPM.

Purpose of the Integrated Stop Ring

The stop ring is highly functional, serving automated systems to eliminate manual intervention:

ARC Systems: Tailor-made for Zund cutters operating the Automatic Router Bit Changer (ARC). The carousel grabs, seats, and drops the bit based on the ring's exact vertical offset.
QC Spindles: Compatible with pneumatic Quick-Change (QC) router modules (such as the RM-A QC and RM-A QC ARC heads).
Instant Calibration: Guarantees identical height registry, preventing the tool tip from crashing into the matrix bed or failing to cut through the material completely.

Target Material Applications

The dual-flute upcut design balances rapid chip evacuation with structural rigidity. It is primarily engineered for deep-plunge milling through lightweight, thick, or semi-rigid substrates:

Technical Foams: Polyethylene (PE) foams, cross-linked polyethylene, and Expanded Polystyrene (XPS).
Signage Backings: Thick, dense hardfoam boards and lightweight sandwich materials.
