Designed for woodworkers who demand consistent molding profiles on hardwood, softwood, MDF, and chipboard, these KSS-style knives deliver long-lasting performance run after run. Whether you are profiling cabinet doors, shaping decorative molding, or producing frame and panel work on a spindle moulder or profile and edging machine, the 690.048 pair provides the precision and durability that production and craft woodworking applications require.

Key Features

• Alloyed steel construction - provides the toughness and edge retention needed for extended use in demanding shaping and profiling operations, reducing downtime between tool changes.
• 40x4mm (1-37/64 in. x 5/32 in.) knife size - fits the CMT insert shaper system cutter heads and other universal cutter heads accepting this standard knife dimension, giving you broad machine compatibility.
• Sold as a matched pair (2 knives) - both knives in the set are matched to the same profile, ensuring balanced cutting and a smooth, consistent surface finish on every pass.
• Variety of profile options within the CMT insert system - the 690.048 is one of many available profile knives in the universal cutter head lineup, allowing you to expand your shaping capabilities by adding or swapping profiles as your projects evolve.
• Long-lasting performance - built to maintain a sharp, accurate edge over many production runs, reducing the frequency and cost of replacement in both shop and industrial settings.

Why This Product

• For woodworkers already invested in the CMT universal cutter head system, these 40x4mm profile knives slot directly into existing cutter heads - eliminating the need to purchase new tooling bodies when you want to add a new shaping profile to your workflow.
• The alloyed steel material keeps the cutting edge sharp across a wide range of workpiece materials - from dense hardwoods and softwoods to engineered sheet goods like MDF and chipboard - making this a versatile choice for cabinet shops, millwork operations, and furniture makers alike.
• Receiving a matched pair means both knives are ready to mount together for balanced, vibration-free cutting - critical for achieving a clean, scratch-free surface on moldings, edges, and profiles without additional setup or matching work on your part.
• Profile number 048 is one of a broad range of CMT insert system knives, so shops that need multiple profiles can build a library of interchangeable knives that all work with the same cutter head bodies, saving tooling costs and storage space over time.
