CWT/CWX ER66.6C Rainbow Coated Single O-Flute Upcut Router Bit

The CWT/CWX ER66.6C router bit is engineered for precision routing on CNC flatbed cutting systems used in signage production, plastics fabrication, packaging manufacturing, and industrial machining. Constructed 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 longer tool life in demanding production environments.

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 and 12 mm cutting edge length (CEL) deliver a rigid cutting profile ideal for accurate profiling, slotting, and through-cut routing in a wide range of rigid materials.

With a shorter 50 mm overall tool length, the ER66.6C offers increased stability and reduced deflection, making it especially well suited for precision routing tasks where tool rigidity and edge quality are critical.

Typical production applications include:

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

• Routing ACM panels such as Dibond®, E-Panel®, and Max Metal®

• Plastics machining for displays, retail 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.
