Product Description
CMT Metrik Knives 5-29/32" x 1-3/16" x 1/8" by CMT are precision-milled High-Speed Steel planer and jointer knives engineered for clean, accurate stock removal on stationary planers and jointers. Supplied as a matched 2-piece set, these balanced HSS blades are designed for consistent performance across a full 180mm cutting length, making them a dependable choice for woodworkers who demand reliable results when surfacing dry softwood, hardwood, and sheet goods alike.
Key Features
- High-Speed Steel (HSS) construction - delivers long-lasting cutting life and retains a sharp edge through demanding planing and jointing sessions, reducing the frequency of knife changes.
- Balanced and milled knives - each knife is precision-milled to exacting tolerances, ensuring smooth vibration-free operation and a flat, consistent surface finish on every pass.
- 180mm (5-29/32") total length - matches the cutting width of compatible stationary planers and jointers, providing full-width coverage without gap or overlap.
- 3mm (1/8") tooth thickness - provides a rigid, stable cutting profile that resists deflection under load for cleaner, more predictable cuts.
- 30mm (1-3/16") cutting height and cutting depth - gives ample stock for multiple resharpenings, extending the service life of each knife before replacement is needed.
- 2-piece matched package - knives are supplied as a balanced pair, so both sides of the cutterhead are replaced simultaneously for uniform cutting performance and proper machine balance.
- Special dimensions available on request - offers flexibility for non-standard machine configurations that fall outside common stock sizes.
Why This Product
- Balanced and precision-milled HSS blades reduce vibration at the cutterhead, which translates directly to a smoother surface on planed boards and less sanding time after machining.
- The 180mm cutting length and 30mm cutting height are purpose-matched to common stationary planer and jointer cutterhead configurations, simplifying knife selection and fitment.
- Selling as a 2-piece matched set ensures both cutterhead slots are fitted with knives of equal weight and geometry, maintaining proper dynamic balance and protecting the machine from premature bearing wear.
- High-Speed Steel material offers a practical balance of sharpness and toughness for woodworkers milling a variety of species, from dry softwoods to hardwoods, without frequent blade swaps.

Frequently Asked Questions
What material are these planer knives made from?
These knives are manufactured from HSS (High-Speed Steel). HSS offers a combination of sharpness and durability that makes it well suited for planing and jointing both softwoods and hardwoods in stationary machine applications.
How many knives are included in this package?
This package contains 2 knives. They are supplied as a balanced, matched pair intended to be installed together in the cutterhead of your planer or jointer to maintain proper balance and uniform cutting performance.
What are the exact dimensions of these knives?
Each knife measures 180mm (5-29/32") in total length, 30mm (1-3/16") in cutting height, 30mm in cutting depth, and 3mm (1/8") in thickness. These dimensions correspond to the 792.180.30 specification used in compatible CMT Metrik cutterhead configurations.
Can these knives be resharpened?
Yes. The 30mm cutting height provides ample material for multiple resharpening cycles, allowing you to restore a sharp edge and continue using the knives before eventual replacement is required, helping to reduce long-term tooling costs.
