Product Description
CMT Solid Carbide Reversible Insert Knives (4/35 deg.) 10.5x10.5x1.5mm F4 are precision-ground, indexable carbide cutting inserts engineered for demanding profiling and shaping applications on spindle moulders, profile machines, and compatible cutter head systems. Each square knife features four usable cutting edges ground at a 35 deg. bevel angle, so when one edge dulls, simply rotate to the next for continued high-quality cuts - extending usable life well beyond a single-edge tool. Manufactured from K2250 solid carbide, these reversible inserts deliver consistent performance across hardwood, softwood, MDF, chipboard, and plywood. This listing is for a 10-piece pack.
Key Features
- K2250 Solid Carbide Material - this premium carbide grade maintains a sharp, stable cutting edge under high-frequency use, reducing the need for frequent replacement and keeping profiling quality consistent over time.
- Four Cutting Edges at 35 deg. Bevel Angle - the reversible, indexable design means you get four fresh cutting edges per knife, multiplying the value of each insert and minimizing downtime spent changing tooling.
- 10.5 x 10.5 x 1.5mm Knife Dimensions - precise, consistent sizing ensures each knife seats correctly in compatible cutter heads, delivering repeatable profile accuracy across every workpiece.
- Standard Reversible (F4) Insert Format - the F4 indexable knife standard ensures broad compatibility with CMT 692 series cutter heads and other compatible insert shaper systems, making these a practical fit for many existing shop setups.
- 10-Piece Pack Quantity - stocking multiple inserts means you always have a fresh edge ready, reducing interruptions during production runs and keeping workflows moving.
- Precision-Ground Construction - tight manufacturing tolerances translate directly to clean, burr-free profiles on molding, rabbeting, grooving, and edge profiling operations.
Why This Product
- With four indexable cutting edges per knife and a 10-piece pack, you have a total of 40 cutting edges on hand - making this an economical choice for shops that run high volumes of profiling, jointing, or grooving work.
- The 35 deg. bevel geometry and K2250 carbide grade are suited for cutting both solid wood species and engineered sheet goods like MDF and chipboard, reducing the need to swap tooling when switching between materials.
- The standard F4 reversible knife format fits CMT 692 series cutter heads and compatible insert shaper systems, so these inserts integrate into existing tooling setups without requiring new hardware investments.
- At 10.5 x 10.5 x 1.5mm with a 35 deg. bevel, the knife geometry is purpose-built for precision insert shaper work - delivering profile consistency that matters when running production quantities of molded or shaped parts.

Frequently Asked Questions
How many cutting edges does each knife have, and how does the reversible design work?
Each 790.105.03 knife has 4 cutting edges ground at a 35 deg. bevel angle. When one edge becomes dull, you simply index the knife to the next edge and continue cutting - no resharpening required. With 10 knives in the pack, you have a total of 40 cutting edges available.
What cutter head systems are these knives compatible with?
These F4 standard reversible knives are designed to fit CMT 692 series cutter heads and other compatible insert shaper systems used on spindle moulders, profile machines, and similar equipment. Always verify your cutter head's knife slot dimensions against the 10.5 x 10.5 x 1.5mm knife size before installing.
What materials can these solid carbide insert knives cut?
The K2250 solid carbide construction is suited for cutting hardwood, softwood, MDF, chipboard, and plywood - making these knives useful across a range of profiling, molding, grooving, and jointing operations without needing to swap insert grades between material types.
What does the "F4" designation mean for these reversible knives?
The F4 designation refers to the standard indexable knife format - specifically, a reversible square knife with 4 cutting edges at a 35 deg. bevel angle and dimensions of 10.5 x 10.5 x 1.5mm. This format, also referenced as HWM-KCR08, identifies the knife's seat geometry for use in compatible insert cutter head systems.
