Product Description
CMT Solid Carbide Reversible Insert Knives - 15x15x2.5mm, R=100mm, 30 deg. Bevel, 4 Edges, 10-Pack are precision-ground tungsten carbide insert knives engineered for demanding profiling and molding work on spindle moulders, profile machines, and compatible router table cutter head systems. Each square insert features a 100mm radius grind and a 30 deg. bevel angle, delivering clean, repeatable profiles in hardwood, softwood, MDF, chipboard, and plywood. With four usable cutting edges per knife and ten knives per pack, this set provides exceptional long-term value for production woodworking environments.
Key Features
- Solid Carbide K1920 Grade Construction - tungsten carbide material provides substantially longer edge life compared to high-speed steel, reducing downtime for insert changes during high-volume profiling runs.
- Four Reversible Cutting Edges per Insert - rotate the square insert to a fresh edge when one dulls, multiplying usable life and lowering cost-per-profile over time.
- 30 deg. Bevel Angle with R=100mm Radius - precisely matched geometry delivers consistent, smooth profile results on curved and contoured workpieces without secondary hand finishing.
- 15x15x2.5mm Insert Dimensions - compact square format fits CMT 692 series cutter heads and compatible insert shaper systems, enabling quick, accurate tool changes at the machine.
- Precision Ground to Exact Tolerances - each knife is ground to tight dimensional standards, ensuring profile consistency from insert to insert and across the full ten-piece pack.
- 10 Knives per Pack - a generous supply keeps production moving without repeated reordering, supporting continuous workflow on spindle moulders and profile machines.
Why This Product
- The K1920 solid carbide grade stays sharp longer in abrasive materials like MDF and chipboard, making these inserts a practical choice for shops that run mixed-species or engineered wood profiles on a regular basis.
- Four cutting edges per insert means a single knife can be rotated three times before replacement, stretching consumable budgets further in production settings without compromising cut quality.
- The 100mm radius and 30 deg. bevel geometry are matched to CMT 692 series cutter head systems, so these knives drop into compatible tooling without fitment guesswork or additional setup time.
- A ten-piece pack quantity provides a ready inventory of inserts, reducing the risk of mid-job stoppages when a cutting edge needs rotation or replacement during continuous profiling work.

Frequently Asked Questions
What cutter head systems are these insert knives compatible with?
These solid carbide knives are designed to fit CMT 692 series cutter heads and compatible insert shaper systems used on spindle moulders, profile machines, and router tables equipped with a matching cutter head body.
How many cutting edges does each knife have, and how do I get the most out of them?
Each 15x15x2.5mm square insert has 4 cutting edges. When one edge dulls during use, simply rotate the insert to the next unused edge in the cutter head. This allows up to four full cutting sessions per knife before replacement is needed.
What materials can these carbide knives cut effectively?
The K1920 solid carbide grade is well suited for profiling hardwood, softwood, MDF, chipboard, and plywood. Carbide maintains its edge longer than high-speed steel in abrasive engineered wood materials such as MDF and chipboard.
What does the R=100mm specification mean for my profiling work?
The R=100mm designation refers to the radius ground into the cutting edge of each knife. This 100mm radius, combined with the 30 deg. bevel angle, determines the curved profile shape that the insert will produce on the workpiece. Confirm that this radius matches your intended profile before use.
