Amana Tool RCK-400 is the exact Tool No. verified directly on its official product page. The dedicated specification matrix establishes a 1/8-inch (3.2mm) diameter, a 13/32-inch (10mm) cutting height, and a 1-1/2-inch (38mm) overall length. Built entirely from industrial micrograin solid carbide, this straight plunge insert blade delivers long-lasting edge sharpness and superior wear resistance under rigorous high-volume production cycles.

Designed primarily for industrial signmaking, modern packaging prototyping, and specialized panel-processing operations, this folding and engraving knife blade excels at producing clean scores, precise structural creases, and geometric cutouts. The straight plunge design facilitates flawless vertical penetration, allowing computerized tangential knife systems to track intricate detailing without material tearing or deflection.

The micrograin construction provides excellent performance across a diverse range of materials, including corrugated cardboard, folding boxboard, dynamic foam core, heavy-duty vinyls, flexible plastics, and thick paper packaging composites. As an interchangeable insert component, the RCK-400 allows rapid, cost-effective replacement without requiring the removal or recalibration of the primary cutting head assembly.
