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

The CWT/CWX ER66.5F router bit is engineered for deep routing operations 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 during demanding high-speed routing applications.

The single O-flute right-hand spiral (upcut) geometry ensures efficient chip evacuation and reduces heat buildup when machining plastics, composite materials, aluminum panels, and lightweight metals. Its 6 mm cutting diameter combined with a 32 mm cutting edge length (CEL) allows deep routing passes in thicker materials while maintaining clean edges and stable cutting performance.

With a 64 mm overall tool length, the ER66.5F provides extended reach for machining thicker boards, stacked materials, and deep profile cuts commonly required in sign fabrication and industrial routing environments.

Typical production applications include:

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

• Deep routing of ACM panels such as Dibond®, Alucobond®, and Reynobond

• Plastics machining for displays, fixtures, and industrial components

• Aluminum and Chromaluxe® panel trimming and profiling

• Wood routing for MDF, plywood, and fabrication templates

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.
