CMT Solid Carbide Reversible Insert Knives - 14x14x1.2mm, 4 Cutting Edges, 30 deg. Bevel - 10-Pack are precision-ground throwaway-style carbide knives engineered for indexable cutter head systems used in spindle moulding, profile machining, and edge-forming applications. Built from K1920 grade solid carbide (tungsten carbide), these reversible insert knives deliver extended cutting life across hardwood, softwood, MDF, chipboard, and plywood. With four usable cutting edges per knife and a 30 deg. bevel angle, each insert offers maximum value per piece - simply rotate to a fresh edge when one dulls, without the cost or downtime of resharpening.

Key Features

• K1920 Solid Carbide Material - tungsten carbide construction resists wear and heat buildup, extending service life significantly compared to high-speed steel inserts when cutting hardwood, softwood, MDF, and chipboard.
• 4 Cutting Edges Per Knife - each insert provides four usable edges, so you get four times the cutting life from a single knife before replacement is needed, reducing overall tooling cost.
• 30 deg. Bevel Angle - the precise 30 deg. cutting geometry produces clean, consistent profiles and reduces tear-out on natural wood and engineered panels.
• Reversible Throwaway Design - rotate the insert to expose a fresh edge rather than removing the cutter head for resharpening, minimizing machine downtime and keeping production moving.
• 14x14x1.2mm Dimensions - compact square profile fits standard indexable cutter head systems on spindle moulders and profile machines, ensuring repeatable, accurate seating every time.
• Precision Ground to Exact Tolerances - consistent geometry across every knife in the pack means each edge performs identically, resulting in uniform profile quality from the first cut to the last.
• 10-Piece Pack - supplied in a pack of 10 knives, providing ample inventory for extended production runs or a ready supply of replacement inserts on hand.

Why This Product

• Four cutting edges per insert mean you get four times the use before a knife is retired - an efficient choice for shops running high volumes of profiling, moulding, or grooving work on wood and panel products.
• The K1920 carbide grade is specifically selected for insert knife applications, offering a balance of hardness and toughness suited to the interrupted cutting conditions common in cutter head systems.
• The reversible, throwaway design eliminates the need for a knife grinding setup - simply index to a new edge or swap in a fresh knife, keeping your spindle moulder or profile machine productive with minimal interruption.
• A pack of 10 knives ensures you always have replacement inserts available, reducing the risk of production delays caused by a worn edge and no spare on the shelf.
