Product Description
CMT 794.332 3-Piece High-Speed Steel Planer and Jointer Knives are precision-ground cutting tools designed for stationary planers and jointers working with a wide range of wood species. Crafted from fine European high-speed steel with a 13% tungsten (13%W) composition, these HSS planer blades deliver a high-quality surface finish on dry softwood, dry hardwood, and even wet hardwood - making them a dependable choice for both production shops and serious woodworkers. Each set includes 3 knives measuring 13-1/8 in. in length, ensuring direct compatibility with machines calling for that knife size.
Key Features
- 13% Tungsten High-Speed Steel (HS 13%W): The elevated tungsten content in these HSS planer knives increases hardness and heat resistance, meaning the cutting edges stay sharper longer even under demanding planer and jointer workloads.
- Carefully Ground from Fine European High-Speed Steel: Precision grinding from premium European steel stock ensures consistent knife geometry across all 3 blades, which translates directly to flat, uniform stock removal and a smooth planed surface on every pass.
- Suitable for Dry Softwood, Dry Hardwood, and Wet Hardwood: Broad material compatibility means one set of knives handles the full range of common lumber types without requiring a blade change between species.
- High-Quality Finish Performance: These jointer and planer knives are engineered to produce a refined surface finish, reducing the time and effort needed for downstream sanding or finishing steps.
- Set of 3 Knives: A complete 3-piece set provides all the knives needed for a full knife change in one purchase, keeping the cutterhead balanced and ready for immediate use.
- 13-1/8 in. Knife Length: The specific 13-1/8 in. dimension matches machines that call for this knife size, enabling a direct OEM-compatible replacement without modification.
Why This Product
- Woodworkers who process both softwoods and hardwoods - including wet hardwood - benefit from a single knife set that handles the full spectrum of common lumber, reducing tool changeover time and keeping production moving.
- The 13% tungsten high-speed steel formula is a step up in wear resistance compared to standard HSS, which means fewer knife changes and more consistent results over the life of the set.
- Precision grinding from fine European high-speed steel stock ensures each of the 3 knives is dimensionally consistent, so the cutterhead stays balanced and the planed or jointed surface comes out flat and true from the first pass.
- At 13-1/8 in. in length, these blades are sized for direct replacement in compatible planers and jointers, eliminating the guesswork of sourcing the right knife for machines built to that specification.

Frequently Asked Questions
What wood types are these planer knives compatible with?
These CMT high-speed steel planer and jointer knives are suitable for cutting dry softwood, dry hardwood, and wet hardwood, making them a versatile choice for shops working with a variety of lumber species.
How many knives are included in this set?
This set includes 3 high-speed steel planer and jointer knives. A full 3-piece set is required for a complete knife change on most compatible cutterheads, keeping the head properly balanced during operation.
What makes the 13% tungsten steel composition beneficial for planer knives?
The 13% tungsten content in the HS 13%W material grade increases the hardness and wear resistance of the cutting edge compared to standard high-speed steels. This helps the knives maintain a sharper edge through extended use on both softwood and hardwood, and contributes to the high-quality surface finish these knives are designed to produce.
Are these knives precision ground?
Yes. These knives are carefully ground from fine European high-speed steel, ensuring consistent geometry and dimensional accuracy across all 3 blades in the set. This precision grinding is a key factor in achieving flat, uniform results when planing or jointing stock.
