Product Description
CMT Metrik Knives 5-1/8" x 1-3/16" x 1/8" are precision-milled, high-speed steel planer and jointer knives designed for clean, consistent stock removal on both softwood and hardwood. Offered in a matched 2-piece set, these HSS blades are balanced for smooth, vibration-free cutting performance in stationary planer and jointer applications. The knives measure 150mm in total length with a 30mm cutting depth, making them a reliable replacement option for woodworkers who demand repeatable surface quality and long-lasting edge retention.
Key Features
- High-Speed Steel (HSS) construction - delivers excellent edge retention and durability across repeated use in both softwood and hardwood planing applications, reducing the frequency of knife changes.
- Balanced and milled knives - factory-balanced pairs help minimize vibration during cutting, resulting in flatter, more consistent planed surfaces and reduced wear on the planer head.
- 150mm (5-1/8 in.) total length with 30mm cutting depth - dimensioned to fit machines requiring Metrik-format knives, ensuring a proper fit without custom modification.
- 3mm tooth thickness - provides structural rigidity in the knife body, which helps maintain cutting geometry over time and resists deflection under load.
- Sold as a 2-piece matched set - both knives come ready to install as a balanced pair, simplifying the replacement process and helping maintain cutter head balance from the first cut.
- Special dimensions available on request - flexibility to source non-standard sizes means this knife line can serve a wider range of machine configurations beyond the standard 150x30x3mm spec.
Why This Product
- For woodworkers running stationary planers or jointers that accept Metrik-format knives, the 150x30x3mm dimensions match a common specification - reducing the guesswork of finding a correctly sized replacement blade.
- The factory-balanced and milled construction means both knives in the set are matched to each other, which matters for cutter head performance - unbalanced knives can cause surface chatter and premature machine wear.
- HSS construction offers a practical combination of sharpness and toughness for users working with dry softwood, hardwood, and plywood, where a brittle carbide edge may not always be the right choice.
- The 2-piece pack format means you have both knives needed for a full head change in a single purchase, avoiding the need to source individual blades separately.

Frequently Asked Questions
What material are these knives made from?
These knives are constructed from HSS - High-Speed Steel. HSS offers a combination of sharpness and toughness that makes it well suited for planing both softwood and hardwood, including wet hardwood and plywood, where edge durability through varied material densities is important.
What are the exact dimensions of these knives?
Each knife measures 150mm (5-1/8 in.) in total length, 30mm (1-3/16 in.) in cutting depth, 30mm in cutting height, and 3mm (1/8 in.) in thickness. These correspond to the Metrik knife format used on compatible stationary planers and jointers.
How many knives are included in the package?
The package contains 2 knives. They are sold as a matched, balanced pair intended for installation together as a complete knife set on the cutter head - not as individual replacement blades.
Are non-standard sizes available for machines with different knife requirements?
Yes - special dimensions are available on request, according to CMT product data. If your machine requires a knife size outside the standard 150x30x3mm specification, you can inquire about alternate sizing through the appropriate channels.
