Premium Solid Carbide
Crafted entirely from premium micrograin carbide to maximize tool life, eliminate edge wear, and handle dense abrasive composites.


Amana Tool RCK-400 is the exact solid carbide straight plunge insert engraving and folding knife blade featuring a 1/8-inch (3.2mm) diameter, 13/32-inch (10mm) cutting height, and 1-1/2-inch (38mm) overall length designed for high-performance precision computerized material processing.
A precision-engineered micrograin solid carbide industrial insert blade for specialized tangential knife systems, digital cutters, and engraving setups. The exact official Tool No. is RCK-400.
Engineered for compatible tangential tooling units, CNC routers equipped with oscillating/tangential knife attachments, and computerized signmaking machines. Verify toolholder lock, torque specs, and machine alignment before automated cycle activation.
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.
Technical Specifications
Crafted entirely from premium micrograin carbide to maximize tool life, eliminate edge wear, and handle dense abrasive composites.
Engineered for clean vertical machine plunging, ensuring razor-sharp directional entry and flawless corner tracking.
Exact dimensional control matching official Amana Tool parameters of a 1/8" diameter and 13/32" cutting height.
Verify exact part number RCK-400 prior to machine assignment. This product is a replacement insert cutting component designed strictly for mounting into authorized toolholders, tangential knife mechanisms, or CNC digital cutter units. Never use with cracked or uncalibrated mounting hardware. Handle with caution as the cutting face is extremely sharp. Adhere to machine-manufacturer cutting depths, safety rules, and feed provisions.
