Product Description
CMT 790.820 Solid Carbide Knives for Portable Planers are precision-ground, reversible tungsten carbide planer blades sized at 82x5.5x1.1mm - engineered as a direct replacement for Bosch, Makita, and Dewalt 82mm portable electric planers. Sold as a set of 2, these Italian-crafted solid carbide knives deliver consistent planing depth across softwood, hardwood, and plywood surfaces, making them a reliable upgrade or replacement for woodworkers who demand clean, accurate results from their handheld planer.
Key Features
- Reversible Design - each knife offers multiple cutting edges, so when one side dulls you simply rotate to a fresh edge, extending usable life and reducing replacement frequency.
- Solid Carbide (Tungsten Carbide) Construction - harder and more wear-resistant than standard HSS knives, solid carbide holds a sharper edge longer through dense hardwoods, plywood, and abrasive softwoods.
- Precision-Ground to Exact Tolerances - factory-ground geometry ensures each knife seats correctly and delivers a consistent planing depth pass after pass, reducing tearout and surface inconsistency.
- Direct OEM-Replacement Sizing at 82x5.5x1.1mm - dimensioned to match original equipment specifications for Bosch, Makita, and Dewalt 82mm planers, so no modification or shimming is needed during installation.
- Set of 2 Knives Included - both knives arrive ready to install, allowing you to replace the full set simultaneously and maintain balanced cutting performance.
Why This Product
- If your portable planer is leaving ridges or uneven surfaces, worn knives are the likely cause - these precision-ground solid carbide knives restore clean, accurate planing depth without requiring a new tool.
- Solid carbide outlasts standard high-speed steel in demanding applications like hardwood and plywood, meaning fewer knife changes over the life of your projects.
- The reversible design gives you more cutting edges per set, so you get maximum value from each pair before replacement is necessary.
- Sized to fit Bosch, Makita, and Dewalt 82mm portable planers, these knives work across some of the most widely used handheld planer platforms - making them a practical stock item for woodworkers who own any of these tools.

Frequently Asked Questions
Which planers are these knives compatible with?
These 82x5.5x1.1mm knives are sized as a direct replacement for Bosch, Makita, and Dewalt 82mm portable electric planers. The dimensions match OEM specifications, so no modification is required during installation.
What is the advantage of solid carbide over standard planer knife materials?
Solid carbide (tungsten carbide) is significantly harder and more wear-resistant than high-speed steel alternatives. This means the cutting edges stay sharper longer, especially when working with dense hardwoods, abrasive softwoods, or plywood - reducing how often you need to rotate or replace the knives.
How does the reversible design work?
Each knife has more than one usable cutting edge. When the active edge becomes dull, you rotate the knife to expose a fresh edge rather than immediately replacing it. This extends the effective service life of each set and reduces overall tooling cost.
How many knives come in this set, and do I need to replace both at once?
This product includes 2 solid carbide planer knives. It is generally recommended to replace both knives at the same time to maintain balanced cutting and consistent planing depth across the full width of the cut.
