CWT/CWX ERKA5 40° Engraving Router Bit

The CWT/CWX ERKA-5 engraving router bit is engineered for precision engraving, marking, and deep detail routing across a wide range of rigid substrates used in signage production, industrial labeling, and fabrication environments. Manufactured from solid carbide, the tool provides excellent durability, sharp cutting edges, and consistent engraving performance during high-speed CNC routing operations.

This tool features a single-flute engraving geometry with a sharp 40° cutting angle, producing narrow, crisp engraving lines and deep V-grooves ideal for detailed lettering, fine graphics, and precision marking. The tighter angle allows for deeper engraving capability while maintaining sharp definition in engraved text and decorative patterns.

The single-flute design improves chip evacuation, reducing heat buildup when engraving plastics such as acrylic, PVC, and polycarbonate. This helps maintain smooth cutting performance and prevents material melting during engraving operations.

With a 7.5 mm cutting edge length (CEL), the ERKA-5 supports deeper engraving passes and more pronounced groove profiles, making it well suited for detailed engraving in plastics, composite panels, and wood substrates.

Typical production applications include:

• Engraving deep text and logos on acrylic and plastic panels

• Producing detailed graphics and decorative grooves in rigid plastics

• Marking ACM signage panels and composite materials

• Creating industrial labels, control panels, and engraved nameplates

• Engraving wood signage and decorative fabrication components

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.
