Product Description
CMT Solid Carbide Reversible Insert Knives - 14x14x2mm, 4 Cutting Edges, 30 deg. Angle are precision-ground throwaway carbide knives engineered for spindle moulders, profile machines, and insert shaper cutter head systems. Built from CMT's K1920 tungsten carbide grade, these indexable knives deliver consistent, repeatable cutting performance across hardwood, softwood, MDF, chipboard, and plywood. Each reversible insert offers four usable cutting edges, making this 10-piece pack an efficient, long-lasting solution for profiling, moulding, rabbeting, grooving, jointing, and edge work.
Key Features
- K1920 Solid Carbide Material - tungsten carbide construction provides exceptional hardness and wear resistance, extending tool life far beyond high-speed steel alternatives when cutting abrasive materials like MDF and chipboard.
- 4 Reversible Cutting Edges at 30 deg. Angle - each knife offers four indexable cutting edges, so when one edge dulls, simply rotate to a fresh edge rather than replacing the insert, reducing downtime and tooling cost per job.
- Compact 14x14x2mm Profile (Length x Height x Thickness) - precision ground to exact tolerances at 14mm length, 14mm cutting height, and 2mm thickness for consistent profile quality and reliable seating in compatible cutter head bodies.
- Standard Indexable Knife Format (HW-K1920) - conforms to recognized reversible throwaway knife standards, ensuring compatibility with a wide range of insert shaper cutter head systems used on spindle moulders and profile machines.
- 10-Piece Pack - multiple knives included per pack, keeping a ready supply of fresh edges on hand and minimizing machine stoppage between edge changes on production runs.
- Precision Ground Geometry - each knife is ground to close tolerances, delivering uniform cuts and smooth surface finishes that reduce sanding and cleanup time after profiling or moulding operations.
Why This Product
- Four cutting edges per insert mean you get significantly more cutting life from each individual knife - ideal for production environments where reducing tooling costs per linear foot of cut matters.
- The K1920 carbide grade is well matched to abrasive engineered wood products like MDF and chipboard, materials that quickly wear softer tooling, making these knives a practical choice when switching between solid wood and composite panel work.
- The standard reversible throwaway knife format means these inserts are drop-in replacements for a broad range of compatible cutter head systems, avoiding the need for specialized tooling or custom-ground knives for common profiling tasks.
- A 10-piece pack keeps multiple fresh inserts accessible at the machine, reducing interruptions during continuous profiling, jointing, rabbeting, or grooving operations without frequent trips to the tool cabinet.

Frequently Asked Questions
How many cutting edges does each knife provide?
Each CMT 790.140.02 solid carbide insert knife provides 4 cutting edges at a 30 deg. angle. When one edge becomes dull, simply rotate the insert to expose a fresh edge, maximizing the service life of every knife before replacement is needed.
What are the exact dimensions of these insert knives?
Each knife measures 14mm in length, 14mm in cutting height, and 2mm in thickness, with a bore diameter of 6.4mm. Dimensions follow the standard L (length) x H (height) x K (thickness) format used for reversible throwaway insert knives.
What carbide grade is used in these knives, and why does it matter?
These knives are manufactured from K1920 solid carbide. This carbide grade is suited for cutting hardwood, softwood, MDF, chipboard, and plywood, providing the hardness and edge retention needed to maintain cut quality on both solid wood and abrasive engineered wood products.
What types of machines are these knives compatible with?
These standard reversible indexable knives are designed for use in insert shaper cutter head systems, including those used on spindle moulders, profile machines, edging machines, and router tables equipped with compatible cutter heads that accept the 14x14x2mm reversible knife format.
