Product Description
CMT Solid Carbide Reversible Insert Knives - 50x9x1.5mm, 35 deg. Bevel, 4 Cutting Edges (10-Pack) are precision-ground throwaway-style carbide knives engineered for indexable cutter head systems used on spindle moulders, profile machines, and router table setups. Built from K1920 solid carbide (tungsten carbide), these insert knives deliver long-lasting cutting performance on hardwood, softwood, MDF, chipboard, and plywood. Each knife features four usable cutting edges at a 35 deg. angle, meaning a fresh edge is always ready without stopping to resharpen - maximizing uptime and value per knife.
Key Features
- K1920 Solid Carbide Material - tungsten carbide construction provides significantly greater hardness and wear resistance compared to HSS, translating to extended service life on dense hardwoods, engineered sheet goods, and abrasive composites.
- 4 Cutting Edges at 35 deg. Bevel - each knife offers four indexable cutting edges, so when one edge dulls, the knife is simply rotated to expose a fresh edge, reducing downtime and the cost of replacement inserts.
- Standard Reversible (Throwaway) Design - the reversible insert format is compatible with indexable cutter head systems, allowing fast edge changes without removing the cutter head from the machine.
- Precision Dimensions: 50mm x 9mm x 1.5mm - consistent length, cutting height, and thickness tolerances ensure repeatable profile quality and proper seating in compatible insert shaper systems.
- 10-Piece Pack - stocking multiple knives means extended production runs between supply replenishments, reducing interruptions in high-volume profiling and moulding operations.
- Precision Ground Finish - each knife is ground to exacting tolerances for a consistent, smooth cut surface across profiling, rabbeting, grooving, jointing, and edge-forming applications.
Why This Product
- Four indexable cutting edges per knife means you get four times the usable life from each insert - a practical advantage over single-edge knives when running high-volume moulding or profiling jobs on hardwood and MDF.
- The K1920 solid carbide grade is engineered for tough woodworking applications where abrasive materials like chipboard and plywood would quickly degrade a standard steel knife, keeping your cutter head performing at spec longer.
- Standard 50x9x1.5mm dimensions and a 35 deg. bevel angle match widely used indexable cutter head formats, making these knives a straightforward fit for compatible spindle moulder and profile machine setups.
- The 10-pack format ensures a ready supply of fresh insert knives on hand, so edge changes during production do not require a separate supply order before work can continue.

Frequently Asked Questions
How many usable cutting edges does each knife have?
Each knife has 4 cutting edges at a 35 deg. bevel angle. When one edge becomes dull, the insert can be rotated to expose a fresh edge, so you get four full cutting cycles from a single knife before it needs to be replaced.
What does the 50x9x1.5mm dimension refer to?
The dimensions follow the standard L (length) x H (height) x K (thickness) format. That means each knife is 50mm in total length, 9mm in cutting height, and 1.5mm in thickness. These are the critical measurements for confirming compatibility with an indexable cutter head system.
What materials can these solid carbide insert knives cut?
These K1920 solid carbide knives are suited for cutting hardwood, softwood, MDF, chipboard, and plywood. The carbide grade provides the hardness and abrasion resistance needed for engineered sheet goods and dense natural wood species that would wear down softer knife materials much faster.
What type of machines are these knives designed for?
These reversible insert knives are designed for use in indexable cutter head systems on spindle moulders, profile machines, edging machines, and router tables equipped with compatible insert shaper cutter heads. Always confirm your cutter head accepts 50x9x1.5mm reversible insert knives with a 35 deg. bevel before installing.
