CMT 690.599 Blank Knives (To Be Sharpened) - 1 11/32" x 2" - 2-Pack from CMT are high-speed steel profile knife blanks designed for use with insert shaper cutter head systems. Sold as a pair, these unsharpened knives give woodworkers and professional millwork shops the freedom to grind any custom molding profile they need - making them an ideal choice for bespoke molding production, cabinet door profiling, and frame-and-panel work. Each blank is precision-manufactured from HSS (high-speed steel) material at 50 x 4mm, ready to be sent to a sharpening service or ground in-house to match a specific profile up to a maximum of 20mm (25/32").

Key Features

• High-Speed Steel (HSS) Construction - the SP-grade material offers the toughness and edge-holding capacity needed for demanding profile grinding and sustained shaper use on hardwood and softwood alike.
• Blank (Unsharpened) Design - allows users or a professional sharpening service to grind any desired profile into the knife, giving full control over molding shape without being locked into a factory profile.
• Maximum Profile Capacity of 20mm (25/32") - accommodates a wide range of molding and edge profiles within a single knife blank size, reducing the need for multiple specialized knife sets.
• 50 x 4mm Knife Dimensions (Total Length 46mm, Relative Length 34mm) - precise blank geometry ensures consistent seating in compatible insert shaper cutter heads for repeatable, accurate cuts.
• Sold as a Matching Pair - both knives in the pack are matched to the same blank dimensions, so the set is ready for balanced installation in a dual-knife cutter head without additional sourcing.
• Teeth Thickness of 0.157" - consistent blade thickness supports stable registration in the cutter head slot, contributing to smooth surface finish and reduced vibration during profiling passes.

Why This Product

• Custom profile work demands flexibility - these blank knives let you define the exact molding shape rather than choosing from a fixed catalog, making them the practical choice for one-off profiles, restoration millwork, or matching existing architectural details.
• The 20mm maximum profile depth (25/32") covers the majority of common molding and edge profiles, meaning a single pair of 690.599 blanks can serve multiple projects once sharpened to different profiles over their service life.
• HSS material withstands the heat and stress of repeated sharpening cycles better than softer steels, so these blanks can be reground multiple times before replacement - extending the value of each pair.
• With a cutting height of 1 31/32" and matched pair format, these knives integrate directly into insert shaper systems that accept 50 x 4mm knives, eliminating fit issues and simplifying setup for production runs.
