Product Description
CMT 690.548 Profile Knives for Insert Shaper System are alloyed steel shaper knives designed to work with CMT universal cutter heads, delivering consistent molding profiles and long-lasting cutting performance. Sold as a pair, these 1-31/32 in. x 5/32 in. (50x4mm) knives are built for woodworkers who demand repeatable, clean profiles in hardwood, softwood, MDF, and chipboard applications. Whether you are shaping cabinet door edges, running molding profiles, or producing frame and panel work, the CMT insert shaper knife system gives you the flexibility to swap profiles quickly and keep production moving.
Key Features
- Alloyed steel construction - provides durability and long-lasting performance through extended production runs, reducing the need for frequent knife replacement.
- 1-31/32 in. x 5/32 in. (50x4mm) knife dimensions - sized to fit CMT universal cutter heads in the 692 series, ensuring a secure, precise fit without modification.
- Profile number 548 design - delivers a specific, repeatable molding profile so every workpiece comes out consistent, run after run.
- Part of CMT's variety of insert shaper profile knives - interchangeable within the universal cutter head system, so one cutter head body handles many different profiles by simply swapping knives.
- Sold as a matched pair - both knives are balanced and matched to each other, maintaining smooth, vibration-free cutting and an even surface finish.
- 35mm radius - the precise geometry of the profile produces clean, smooth curves in molding and edge profiling work without secondary sanding passes.
Why This Product
- The insert shaper system design means you invest once in a universal cutter head body and expand your profile library simply by adding knife pairs - a cost-effective approach for shops that run multiple molding profiles.
- Alloyed steel construction is engineered for long-lasting performance, making these knives a reliable choice for production environments where downtime from dull tooling is costly.
- At 1-31/32 in. cutting height and 5/32 in. maximum thickness, the 690.548 knives fit the 50x4mm insert slot found on CMT 692 series cutter heads, eliminating compatibility guesswork.
- Buying knives as a matched pair ensures both cutters wear evenly and maintain the same cutting geometry, which is critical for achieving a smooth, balanced finish on profiled edges and moldings.
