CWT/CWX ER66.5E Rainbow Coated Single O-Flute Upcut Router Bit

The CWT/CWX ER66.5E is a multi-purpose single O-flute super carbide router bit with a premium rainbow coating for lubricity and tool life enhancement and an integrated stop ring, designed for high-speed routing of plastics, ACM panels, aluminum, and wood. The precision collar enables reliable automated use with Zünd ARC router systems and the CUTWORX Tool Changer.

Product Description

The CWT/CWX ER66.5E router bit with stop ring is engineered for precision routing on CNC flatbed cutting systems used in signage production, plastics fabrication, packaging manufacturing, and industrial machining. Manufactured from super-grade solid carbide and enhanced with a premium rainbow coating for lubricity and tool life enhancement, this tool delivers excellent wear resistance, reduced cutting friction, and improved thermal performance during high-speed routing operations.

The single O-flute right-hand spiral (upcut) geometry promotes efficient chip evacuation while minimizing heat buildup when machining plastics, composite materials, aluminum panels, and lightweight metals. Its 6 mm cutting diameter combined with a 22 mm cutting edge length (CEL) provides added strength and rigidity, making it ideal for deeper routing passes and thicker materials while maintaining clean edges and accurate profiles.

This model includes a precision stop ring (collar) designed for consistent tool positioning when used with Zünd ARC automated routing systems and the CUTWORX Tool Changer, ensuring reliable automated tool changes and repeatable cutting performance in production workflows.

Typical production applications include:

• Signage fabrication using acrylic, PVC, and aluminum composite materials

• Routing ACM panels such as Dibond®, Alucobond®, and Reynobond

• Plastics machining for retail displays, fixtures, and packaging prototypes

• Aluminum and Chromaluxe® panel trimming and profiling

• Wood routing for MDF templates, plywood components, and fabrication parts

Note: 6 mm shank router bits are designed for CUTWORX Apex Plus and Apex M Series flatbed cutters equipped with the 1.8 kW liquid cooled router spindle.
