Product Description
CMT Solid Carbide Reversible Insert Knives (2 cutting edges, 35 deg. bevel) - 50x12x1.5mm - 10-Pack are precision-ground throwaway insert knives engineered for spindle moulders, profile machines, and compatible cutter head systems. Manufactured from K2250 grade solid carbide (tungsten carbide), these indexable knives deliver exceptional edge retention across hardwood, softwood, MDF, chipboard, and plywood. Each knife features two usable cutting edges at a 35 deg. angle, meaning when the first edge dulls you simply rotate to a fresh edge - doubling the effective service life per knife and reducing downtime on the job. The pack of 10 ensures you have ample supply for production runs and keeps your cutter head system running at peak performance.
Key Features
- K2250 Grade Solid Carbide Construction - tungsten carbide material provides significantly longer cutting life compared to HSS alternatives, making these knives well suited for abrasive sheet goods like MDF and chipboard as well as dense hardwoods.
- 2 Cutting Edges at 35 deg. Bevel - reversible (throwaway) design lets you index to a second cutting edge when the first dulls, effectively giving you twice the cutting life per knife and maximizing value per pack.
- 50 x 12 x 1.5mm Precision Dimensions - exact tolerances in length, height, and thickness ensure consistent profile quality, repeatable results, and reliable seating in compatible insert cutter heads.
- Standard Indexable Knife Format - fits CMT 692 series cutter heads and compatible insert shaper systems, making these a straightforward drop-in replacement for production and shop environments.
- 10-Piece Pack - bulk quantity keeps your production line or shop supplied, reducing the frequency of reorders and ensuring a fresh knife is always on hand.
Why This Product
- The K2250 solid carbide grade retains a sharp cutting edge far longer than standard steel knives, making this an efficient choice for high-volume profiling and moulding work in hardwood and engineered wood materials.
- With two usable 35 deg. cutting edges per knife, you get more total cutting time before disposal - a practical advantage that lowers cost per linear foot of material processed.
- The 50 x 12 x 1.5mm standard format is compatible with CMT 692 series cutter heads and comparable insert shaper systems, so these knives integrate smoothly into existing setups without requiring new tooling investment.
- Buying in a 10-piece pack means you have a ready supply for edge profiling, rabbeting, grooving, and jointing operations - reducing interruptions when working through demanding production schedules.

Frequently Asked Questions
How many cutting edges does each knife have, and how do I extend its life?
Each knife has 2 cutting edges ground at a 35 deg. bevel. When the first edge becomes dull, simply remove the knife, rotate it 180 deg., and reinstall it to expose the second fresh cutting edge. This reversible (throwaway) design effectively doubles the usable life of each knife before replacement is needed.
What cutter heads are these knives compatible with?
These 50 x 12 x 1.5mm solid carbide insert knives are designed for CMT 692 series cutter heads and compatible insert shaper systems used on spindle moulders, profile machines, edging machines, and router tables equipped with appropriate cutter heads.
What materials can these solid carbide knives cut?
The K2250 grade solid carbide construction makes these knives well suited for cutting hardwood, softwood, MDF, chipboard, and plywood. The carbide grade is particularly effective on abrasive materials such as MDF and chipboard where high-speed steel knives tend to lose their edge more quickly.
How many knives come in a pack, and what are the exact knife dimensions?
Each pack contains 10 knives. The dimensions for each knife are 50mm in total length, 12mm in height, and 1.5mm in thickness - matching the standard K192 indexable knife format designation used with compatible cutter head systems.
