Product Description
CMT Metric Planer and Jointer Knives - 500 x 35 x 3mm (19-11/16" x 1-3/8" x 1/8"), 2-Piece Set by CMT are high-speed steel replacement blades engineered for stationary planers and jointers requiring metric knife dimensions. Each knife in this matched pair is precision-ground to exact tolerances, delivering razor-sharp cutting edges that produce clean, consistent stock removal on softwoods, hardwoods, and sheet goods. Whether you are restocking a metric-spec planer or upgrading worn blades on a jointer, this 2-piece set keeps your machine running at full performance.
Key Features
- High-Speed Steel (HS) material - provides long cutting life and maintains edge integrity through demanding planing and jointing sessions, reducing the frequency of blade changes.
- Mirror-finish grinding on cutting edges - produces razor-sharp, extremely durable edges right out of the package, so surfaces come off the planer or jointer smooth with minimal tear-out.
- Metric knife dimensions of 500 x 35 x 3mm - matches machines specified in metric measurements, eliminating the guesswork of adapting imperial-sized knives to metric tool bodies.
- 2-piece matched set - sold as a balanced pair so both knives can be replaced simultaneously, maintaining even cutter-head balance and consistent cut quality across the full board width.
- 35mm cutting depth and 35mm cutting height - supports substantial material removal capacity, making these knives suitable for both light finishing passes and heavier dimensioning work.
- 3mm teeth thickness - provides the rigidity needed to hold a true, flat cutting plane without flex under load, contributing to flat, accurate planed surfaces.
Why This Product
- If your planer or jointer calls for 500mm metric knives, these blades are a direct-fit solution - no grinding, shimming, or modification required to match the specified 500 x 35 x 3mm profile.
- The mirror-finish high-speed steel construction means sharper edges from the start and a longer service interval compared to lower-grade blade materials, keeping downtime short in production or shop environments.
- Buying a matched 2-piece set ensures balanced knife rotation, which is critical for reducing vibration, protecting the cutter head, and achieving uniformly flat surfaces across every pass.
- Special dimensions are available on request, making this product line a practical long-term source for metric planer knife replacements even when standard sizes do not match a particular machine.

Frequently Asked Questions
What does the mirror finish on these knives actually do for cutting performance?
According to CMT, the mirror finish on these high-speed steel knives produces both razor-sharp and extremely durable cutting edges. In practical terms, this means the blade enters the wood cleanly with less resistance, reducing surface fuzz and tear-out, and the edge holds up longer before it requires resharpening or replacement.
Are these knives sold individually or as a set?
These knives are sold as a 2-piece package. Replacing both knives at the same time is the recommended practice for keeping the cutter head balanced and maintaining consistent, vibration-free cutting across the full width of your workpiece.
What is the exact knife profile, and how do I know if these fit my machine?
The knives measure 500mm total length x 35mm cutting height x 3mm thickness (19-11/16" x 1-3/8" x 1/8"). These are metric-specified knives, so check your planer or jointer manual for the required knife dimensions and confirm they match this profile before ordering. If your required size differs, special dimensions are available on request.
What materials can these planer knives cut?
These high-speed steel knives are suited for use on dry softwood, dry hardwood, wet hardwood, and plywood. The HS material grade provides the edge retention needed to work through denser hardwood species without rapid dulling.
