Micrograin HW Carbide
Premium tungsten carbide supports wear resistance and stable cutting geometry through demanding heat and abrasion cycles.


Precision micrograin tungsten-carbide profile insert engineered for left-hand cutterhead configurations. Its 16 × 13.4 × 2 mm format, R=3.0 mm radius, and engineered clearance geometry support repeatable edge profiling in solid wood, MDF, and layered composite materials.
This premium replacement insert combines micrograin tungsten carbide, an exact R=3.0 mm profile, and left-hand geometry for stable, repeatable profiling in compatible industrial cutterheads.
Designed for compatible left-hand industrial cutter blocks and profiling heads accepting a 16 × 13.4 × 2 mm insert with matching R3 pocket geometry.
The Leitz HW R3 Left-Hand Profile Insert L75328 is a precision replacement component for industrial architectural woodworking, millwork, and panel-processing operations. Its 16 mm length, 13.4 mm height, and 2.0 mm thickness provide a rigid, repeatable fit in compatible profiling cutterheads.
The premium hard-metal tungsten-carbide substrate is designed to resist abrasive wear and impact loading during continuous machining. Its left-hand R=3.0 mm profile supports consistent corner radiusing across solid hardwoods, dense softwoods, MDF, and layered composite materials.
Precision-ground cutting faces and engineered clearance angles help control friction, chip evacuation, and heat generation while reducing fiber tear-out and burn marking. Repeatable insert dimensions simplify replacement and help maintain consistent profile geometry without extensive realignment.
Technical Specifications
Premium tungsten carbide supports wear resistance and stable cutting geometry through demanding heat and abrasion cycles.
Precision-ground geometry helps each replacement insert reproduce the intended 3.0 mm radius with minimal setup variation.
Controlled relief angles help reduce friction, heat buildup, fiber tear-out, and burn marking in dense materials.
Disconnect and isolate the machine before installation. Confirm the 16 × 13.4 × 2 mm dimensions, R=3.0 mm profile, and left-hand orientation against the cutterhead specification. Clean the pocket, backing surface, and locking hardware of resin, dust, and debris, then tighten the clamping screw to the manufacturer-specified torque before operation.
The Leitz HW R3 Left-Hand Profile Insert L75328 is built for continuous industrial profiling where stable geometry and repeatable finish quality are required. Its 16 × 13.4 × 2 mm footprint and dedicated left-hand R3 form support accurate installation in matching cutterhead pockets.
Premium tungsten carbide, micro-balanced construction, and precision-ground clearance geometry help reduce vibration, manual sanding, and profile variation across solid wood, MDF, and composite production components.
