CMT 3-Piece High-Speed Steel Planer and Jointer Knives - 8" Length by CMT are precision-ground replacement blades engineered for stationary planers and jointers that demand consistent, high-quality surface finishes. Crafted from fine European high-speed steel with a 13% tungsten (13%W) composition, these HSS planer knives are built to tackle a wide range of wood types - from dry softwood to both dry and wet hardwood - delivering smooth, flat results with every pass. Whether you are restoring worn blades or upgrading your jointer knives for better performance, this 3-piece set is sized at 8" x 7/8" x 1/8" to serve as a direct replacement in compatible machines.

Key Features

• 13% Tungsten High-Speed Steel construction - the elevated tungsten content gives these HSS planer knives greater hardness and edge retention compared to standard steel, meaning longer intervals between blade changes and more consistent surface quality over time.
• Precision-ground from fine European high-speed steel - each knife is carefully ground to exact tolerances, producing a high-quality finish on workpiece surfaces and reducing the need for additional sanding or smoothing.
• Suitable for dry softwood, dry hardwood, and wet hardwood - the versatile material compatibility means one set of blades handles a broad range of lumber species and moisture conditions commonly encountered in woodworking shops.
• Comes as a set of 3 knives - a complete 3-piece set provides everything needed to replace all blades in a standard planer or jointer head at once, ensuring balanced cutting performance and even wear across all positions.
• Dimensions of 8" x 7/8" x 1/8" - these precise measurements make the knives a direct fit for compatible 8 in. planer and jointer machines, simplifying the replacement process and eliminating guesswork.

Why This Product

• Fine European HSS for superior edge quality - the carefully ground, fine-grain European high-speed steel delivers a cleaner, more refined cut than lower-grade blade materials, making these jointer knives a reliable choice for finish-quality woodworking.
• One set covers multiple wood types - because these blades are rated for both wet and dry hardwood as well as dry softwood, a single purchase handles the full range of lumber commonly used in cabinetry, furniture, and general millwork applications.
• Complete 3-knife set for balanced performance - replacing all cutter-head knives at the same time with a matched set prevents vibration and uneven cutting depth caused by mismatched blade wear, extending the life of the machine and improving surface results.
• Standardized 8 in. dimensions for straightforward installation - the 8" x 7/8" x 1/8" profile is sized to match common planer and jointer head configurations, reducing downtime when swapping out dull blades.
