Product Description
CMT Solid Carbide Reversible Insert Knives - 50x5.5x1.1mm, 35 deg. Bevel, 4 Cutting Edges, 10-Piece Pack are precision-ground throwaway-style carbide insert knives engineered for spindle moulders, profile machines, edging machines, and router tables equipped with compatible cutter heads. Built from K1920 grade solid carbide, these indexable knives deliver long-lasting performance on hardwood, softwood, MDF, chipboard, and plywood - giving woodworkers and production shops a reliable edge in profiling, moulding, rabbeting, grooving, and jointing operations. With four usable cutting edges per knife and a 35 deg. bevel angle, each piece offers maximum value by allowing rotation to a fresh edge as each one dulls, reducing downtime and total tooling cost.
Key Features
- K1920 Solid Carbide Material - tungsten carbide construction delivers significantly longer service life compared to HSS alternatives, staying sharp longer on dense hardwoods, abrasive MDF, and chipboard where softer tool steels wear quickly.
- 4 Reversible Cutting Edges at 35 deg. Bevel - each knife provides four indexed cutting edges, meaning you get four times the usable life from every insert before replacement is needed, lowering your cost per cut.
- Precision Ground to Exact Tolerances - consistent knife dimensions of 50x5.5x1.1mm ensure accurate, repeatable profile quality across every piece of stock, reducing reject rates and setup adjustments.
- Throwaway / Indexable Design - no resharpening required; simply rotate or replace the insert to restore full cutting performance instantly, keeping production moving without machine downtime for grinding.
- 10 Knives Per Pack - the multi-piece pack format keeps spare inserts on hand so a fresh edge is always available, making it practical for high-volume shops and continuous production environments.
- Fits CMT 692 Series Cutter Heads and Compatible Insert Systems - standardized dimensions make these knives compatible with a range of insert shaper systems, simplifying inventory and sourcing across multiple machines.
Why This Product
- For shops running spindle moulders or profile machines through heavy production cycles, the indexable four-edge design means you rotate to a fresh cutting edge instead of stopping to grind - maintaining output without sacrificing surface quality on hardwood, softwood, or sheet goods.
- K1920 solid carbide holds its edge longer than conventional tool steel on abrasive materials like MDF and chipboard, making these inserts the practical choice for cabinet shops and millwork operations that process high volumes of engineered wood products.
- The precision-ground 50x5.5x1.1mm dimensions and 35 deg. bevel angle are held to exact tolerances, so profile consistency is maintained from the first cut to the last - reducing waste and rework on finished moulding runs.
- Purchasing in a 10-piece pack ensures you always have replacement inserts on hand, eliminating the risk of production stalls caused by a dull edge and no spare - a straightforward way to manage tooling inventory for ongoing operations.

Frequently Asked Questions
How many cutting edges does each knife have, and how do I use them?
Each knife has 4 cutting edges at a 35 deg. bevel angle. When one edge dulls, simply loosen the clamping screw on your cutter head, rotate or flip the insert to expose a fresh edge, and retighten. No resharpening is needed - the throwaway design means you index through all four edges and then replace the insert entirely.
What materials can these solid carbide insert knives cut?
These K1920 grade solid carbide knives are suited for use on hardwood, softwood, MDF, chipboard, and plywood. The solid carbide construction is particularly well suited to abrasive engineered materials like MDF and chipboard where high-speed steel tools would dull much more quickly.
What cutter heads are these knives compatible with?
These knives are designed to fit CMT 692 series cutter heads and compatible insert shaper systems used on spindle moulders, profile machines, edging machines, and router tables equipped with an appropriate insert-style cutter head. Always verify the knife slot dimensions on your specific cutter head match the 50x5.5x1.1mm knife size before installation.
What do the knife dimensions 50x5.5x1.1mm refer to?
The dimensions follow the standard L (length) x H (height) x K (thickness) format used for indexable insert knives. This means the knife is 50mm in total length, 5.5mm in cutting height, and 1.1mm thick. These dimensions must match the insert slot specifications of your cutter head to ensure a secure and accurate fit.
