CMT 690.100 Profile Knives for Insert Shaper System - 1-37/64" x 5/32" (40x4mm), 2-Pack by CMT are precision-engineered shaper knives designed to work with the CMT universal cutter head insert system, giving woodworkers the ability to create consistent molding profiles, cabinet door edges, and decorative frame details with repeatable accuracy. Made from alloyed steel, these 40x4mm profile knives are sold as a pair and deliver long-lasting cutting performance across a wide range of profiling and edge-shaping tasks on wood and wood-composite materials.

Key Features

• Pair of alloyed steel profile knives (40x4mm): each set includes 2 matched knives precision-fitted for the CMT insert shaper system, ensuring balanced cutting and a smooth, tear-free surface finish on your workpiece.
• 1-37/64" cutting height: the generous profile height allows you to shape substantial molding depths and decorative contours in a single pass, reducing setup time and improving workflow efficiency.
• 5/32" maximum thickness: the slim knife profile seats securely within the cutter head slot, maintaining accurate registration for consistent results across repeated cuts.
• Compatible with universal cutter heads: these knives are designed for the CMT insert shaper system and are compatible with a variety of universal cutter heads, giving you the flexibility to mix and match profiles without investing in entirely new tooling.
• Long-lasting alloyed steel construction: the use of alloyed steel maintains edge integrity through extended production runs, meaning fewer interruptions for knife changes or resharpening.
• Profile Number 100 - a defined molding profile: the fixed profile geometry produces a predictable, repeatable shape every time, which is essential for production consistency on cabinet door making, frame-and-panel work, and edge profiling.

Why This Product

• Purpose-built for insert shaper versatility: because these 40x4mm knives are designed for a universal cutter head insert system, woodworkers can swap profiles quickly without changing the entire tooling setup - ideal for shops that run multiple molding profiles.
• Sold as a matched pair: receiving 2 knives per pack means you have a balanced set ready to mount immediately, eliminating the guesswork of sourcing individual blades and ensuring the cutter head is properly loaded from the start.
• Alloyed steel for production-grade endurance: the long-lasting performance of alloyed steel makes this pair a practical choice for repetitive profiling operations where edge retention directly impacts cut quality and surface finish.
• Specific, consistent profile geometry: the defined Profile Number 100 shape ensures that every piece you run through the moulder or spindle shaper matches the last, making these knives well-suited to cabinetry, millwork, and frame-and-panel production where uniformity is non-negotiable.
