CMT 690.547 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaper knives sized 1-31/32 in. x 5/32 in. (50x4mm) - engineered for use with CMT universal cutter heads to deliver precise molding profiles, clean edges, and long-lasting performance on a wide range of wood-based materials. Designed as part of the CMT Insert Shaper System, these KSS 50x4mm profile knives give woodworkers and cabinet shop operators the flexibility to switch profiles quickly while maintaining consistent results run after run.

Key Features

• Alloyed Steel Construction - the material used for these profile knives provides durability and resistance to wear, helping them maintain a sharp cutting edge through extended production runs on hardwood, softwood, MDF, and chipboard.
• KSS 50x4mm Knife Size (1-31/32 in. x 5/32 in.) - the standardized 50x4mm format ensures a precise fit in compatible CMT universal cutter heads, eliminating slop or misalignment that could compromise profile accuracy.
• 30mm Radius Profile - delivers a consistent, repeatable curve geometry ideal for molding, edging, and decorative frame work, reducing the need for secondary sanding or shaping operations.
• Part of a Variety of Profile Knives for Universal Cutter Heads - designed to work within CMT's broader insert shaper system, making it straightforward to expand your profile library without investing in entirely new tooling for each application.
• Sold in a Pair of 2 Knives - both knives are matched and ground as a set, ensuring balanced cutting performance and reducing vibration during operation.

Why This Product

• For shops that run a variety of molding profiles, the CMT 690.547 inserts directly into compatible universal cutter heads - letting operators change profiles without replacing the entire tool body, saving time and tooling cost.
• The 30mm radius and precisely ground 50x4mm dimensions mean the profile is repeatable knife to knife and run to run, which is critical for cabinet door making, frame and panel work, and any application where matching pieces must align.
• Alloyed steel construction supports long-lasting performance even on demanding materials like MDF and chipboard, which are known to dull cutting edges faster than solid wood - reducing the frequency of changeovers in production environments.
• Because these knives are sold as a matched pair, both sides of the cutter head are replaced at the same time, maintaining balanced cutting geometry and helping protect the cutter head itself from uneven loading.
