CWT/CWX ER66.7D Rainbow Coated Single O-Flute Downcut Router Bit with Stop Ring

The CWT/CWX ER66.7D 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 provides improved wear resistance, reduced cutting friction, and extended tool life during high-speed routing operations.

The single O-flute left-hand spiral (downcut) geometry pushes chips downward into the material during cutting, helping maintain clean top-edge finishes while minimizing lifting, chipping, or surface damage on laminated or printed materials. This design is particularly beneficial when machining materials where top surface quality is critical, such as printed composite boards, laminated plastics, and coated substrates.

Its 6 mm cutting diameter combined with a 13 mm cutting edge length (CEL) provides excellent rigidity and cutting stability, enabling accurate profiling, slotting, and through-cut routing across a wide range of rigid materials.

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 environments.

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.
