Product Description
CMT Solid Carbide Pair Knives (1/35 deg.) 30x12x1.5mm are precision-ground diamond insert knives engineered for demanding profiling and shaping work. With a 35 deg. single cutting edge bevel and compact 30x12x1.5mm dimensions (length x height x thickness), these solid carbide knives deliver clean, consistent cuts in hardwood, softwood, MDF, chipboard, and plywood. Sold as a pair, they are built to perform in spindle moulders, profile machines, and compatible insert cutter head systems where accuracy and edge durability matter most.
Key Features
- Solid carbide (DP) construction - diamond-grade material resists wear and maintains a sharp edge significantly longer than standard high-speed steel knives, reducing downtime and replacement frequency on production runs.
- 35 deg. bevel angle with 1 cutting edge - optimized geometry for precise profiling and molding cuts, delivering clean entry into the workpiece and a smooth finished surface.
- Compact 30x12x1.5mm profile - the tight dimensional specification (length x height x thickness) ensures accurate registration in compatible cutter heads for repeatable profile results cut after cut.
- Sold as a pair (2 knives per set) - balanced pairing means both knives can be installed together for a properly weighted, vibration-reduced cut on spindle moulders and profile machines.
- Precision-ground to exact tolerances - consistent knife geometry across the pair ensures uniform profile depth and edge quality throughout the full cutting height of 12mm.
Why This Product
- Solid carbide construction means these knives hold their edge through extended runs on dense hardwoods and abrasive engineered sheet materials like MDF and chipboard, where softer knife materials wear out quickly.
- The 35 deg. cutting angle and 1.5mm thickness are matched to insert shaper systems that demand close dimensional tolerances, making these knives a reliable choice for profile consistency across large batches.
- The 12mm cutting height gives adequate depth capacity for typical molding and edge profiling operations, covering rabbeting, grooving, jointing, and decorative profile work without a tool change.
- Paired packaging ensures both cutter head seats are loaded with matched knives, supporting balanced rotation and reducing vibration that could otherwise affect surface finish quality.

Frequently Asked Questions
What do the dimensions 30x12x1.5mm refer to on these carbide knives?
The three dimensions refer to total length (L) x cutting height (H) x thickness (K) in millimeters - specifically 30mm long, 12mm high, and 1.5mm thick. This is the standard dimensional reference format for insert knives used in cutter head systems.
How many knives are included in one order of the CMT 790.300.60?
Each set includes 2 solid carbide knives - sold as a matched pair so both cutter head seats can be loaded simultaneously for balanced cutting performance.
What does the 35 deg. angle indicate on these insert knives?
The 35 deg. value refers to the bevel angle of the single cutting edge. This geometry is designed for the insert shaper systems these knives are built to fit and directly influences how the knife engages the workpiece during profiling cuts.
What materials can these solid carbide knives cut?
These DP-grade solid carbide knives are suited for cutting hardwood, softwood, MDF, chipboard, and plywood - materials commonly encountered in molding, edge profiling, grooving, rabbeting, and jointing operations on spindle moulders and profile machines.
