CMT 3-Piece High-Speed Steel Planer and Jointer Knives - 15 in. x 1 in. x 1/8 in. by CMT are precision-ground replacement blades engineered for stationary planer and jointer machines. Carefully produced from fine European high-speed steel with a 13% tungsten (13%W) composition, these knives deliver a high-quality surface finish on dry softwood, dry hardwood, and even wet hardwood. Whether you are prepping rough-sawn lumber for furniture, flattening boards for cabinetry, or jointing edges for a tight glue line, this set of 3 HSS planer knives provides the cutting performance and durability that demanding woodworking applications require.

Key Features

• 13% Tungsten High-Speed Steel Construction - the elevated tungsten content in this HSS alloy contributes to greater hardness and edge retention compared to standard steel, meaning fewer knife changes and more consistent planing results over extended use.
• Fine European High-Speed Steel, Carefully Ground - each knife is ground from premium European steel stock, producing precise, uniform cutting edges that translate directly into a smooth, flat surface finish on your workpiece.
• 15 in. x 1 in. x 1/8 in. Knife Dimensions - sized to replace standard planer and jointer knives, these blades fit a wide range of stationary machines without modification, reducing downtime when changing out worn blades.
• Suitable for Dry Softwood, Dry and Wet Hardwood - the material versatility of this HSS blade set means one knife set handles a broad range of lumber species and moisture conditions, making it a practical choice for professional shops and serious hobbyists alike.
• Set of 3 Knives Included - matching the typical 3-knife cutterhead configuration found on many planers and jointers, so you can replace an entire cutterhead set in a single purchase without sourcing additional blades.
• High-Quality Finish - precision-ground cutting edges reduce tearout and surface irregularities, helping you achieve board surfaces that require minimal additional sanding before finishing or glue-up.

Why This Product

• Handles wet and dry lumber in a single set - the 13%W high-speed steel formulation is rated for both dry softwood and dry and wet hardwood, so you are not limited to a single material type when switching between stock in the same session.
• Ready to run as a complete cutterhead replacement - because 3 knives are included, you can replace all blades on a standard 3-knife cutterhead at once, ensuring balanced, vibration-free cutting rather than mixing old and new knives.
• Precision-ground edges for professional surface quality - carefully ground from fine European high-speed steel, these knives are designed to produce a high-quality finish directly off the machine, reducing follow-up work on your boards.
• Purpose-built for planer and jointer machines - at 15 in. x 1 in. x 1/8 in., these knives are sized specifically for stationary planer and jointer cutterheads, making them a direct-fit solution for common machine configurations in professional and workshop settings.
