Product Description
CMT Solid Carbide Reversible Insert Knives (4/35 deg.) - 49.2x9x1.5mm - 10-Pack are precision-ground throwaway carbide knives engineered for indexable cutter head systems used in profiling, molding, grooving, and jointing applications. Built from K1920 grade solid carbide, these reversible insert knives deliver consistent cutting performance across hardwood, softwood, MDF, chipboard, and plywood. With four usable cutting edges per knife and a 35 deg. bevel angle, each insert maximizes tool life and reduces per-edge cost on spindle moulders, profile machines, edging machines, and router tables fitted with compatible cutter heads.
Key Features
- K1920 Solid Carbide Material - a high-grade tungsten carbide formulation that maintains a sharp edge far longer than HSS alternatives, reducing downtime and replacement frequency on demanding production runs.
- 4 Cutting Edges at 35 deg. Bevel - each knife provides four usable edges, meaning when one edge dulls, simply rotate or flip the insert to restore full cutting performance without stopping to regrind.
- Reversible Throwaway Design - insert-style construction eliminates the need for sharpening equipment on-site; replace and rotate edges in seconds to keep production moving.
- Precision Ground Dimensions (49.2x9x1.5mm) - exact tolerances across length, height, and thickness ensure consistent profile accuracy and a secure, repeatable fit in compatible indexable cutter head seats.
- Standard Indexable Knife Format - conforms to the standard reversible knife specification, making these inserts compatible with a broad range of CMT and compatible insert shaper cutter head systems.
- 10-Piece Pack - stocking a full pack means you have replacement edges on hand to maintain workflow without waiting, reducing machine downtime on the shop floor.
Why This Product
- Four cutting edges per knife means each insert delivers up to four times the usable life of a single-edge blade - a practical advantage for shops running continuous profiling or molding operations on hardwood and engineered wood materials.
- The K1920 carbide grade is suited for a wide range of wood-based materials including MDF, chipboard, and plywood, making these knives a versatile choice across different workpiece types without needing to swap to a different insert grade.
- At 49.2x9x1.5mm with a 35 deg. bevel, these knives conform to a standard indexable knife format, providing broad compatibility with insert cutter head systems used on spindle moulders, profile machines, edging machines, and router tables.
- Purchasing a 10-piece pack ensures an adequate supply of fresh cutting edges is always within reach, supporting uninterrupted production schedules and reducing the risk of running short during extended machining sessions.

Frequently Asked Questions
How many usable cutting edges does each knife have?
Each knife features 4 cutting edges at a 35 deg. bevel angle. When one edge becomes dull, the insert can be rotated or flipped to expose a fresh edge, extending the useful life of each individual knife before it needs to be replaced.
What materials can these carbide insert knives cut?
These K1920 solid carbide knives are suited for cutting hardwood, softwood, MDF, chipboard, and plywood - covering the range of wood-based materials commonly processed on spindle moulders, profile machines, edging machines, and router tables equipped with compatible indexable cutter heads.
What are the exact knife dimensions?
The knives measure 49.2mm in total length, 9mm in cutting height, and 1.5mm in thickness. These dimensions conform to the standard reversible knife format designated for CMT and compatible indexable insert cutter head systems.
Do these knives require sharpening?
No - these are throwaway reversible insert knives. The design does not call for on-site sharpening. When all four cutting edges on an insert are exhausted, the knife is replaced. The 10-piece pack provides a ready supply of replacement inserts to support continuous operation.
