CMT 3-Piece High-Speed Steel Planer and Jointer Knives - 6 in. Length are precision-ground cutting knives crafted from fine European 13% tungsten high-speed steel (HSS), engineered for demanding planer and jointer applications. Designed to deliver a smooth, high-quality surface finish on both softwood and hardwood, these replacement planer blades are an ideal choice for woodworkers who need consistent cutting performance and extended edge life. Each knife in this 3-piece set is carefully ground to exacting tolerances, making them a reliable option for stationary planer and jointer machines used in professional shops and serious hobbyist workshops alike.

Key Features

• 13% Tungsten High-Speed Steel construction - the elevated tungsten content in this HSS formula helps the cutting edge hold up longer under the friction and heat of repeated planing passes, meaning fewer knife changes and more consistent results over time.
• Carefully ground from fine European high-speed steel - precision grinding from high-quality European steel stock produces a sharp, uniform cutting edge that engages wood cleanly, reducing tear-out and producing a smoother surface.
• Suitable for dry softwood, dry hardwood, and wet hardwood - the material compatibility range means these jointer and planer knives handle a wide variety of lumber types without requiring frequent swaps between different knife sets.
• Set of 3 matched knives - a complete 3-piece set ensures balanced cutter head rotation when all knives are replaced at the same time, which supports even material removal and reduces vibration during operation.
• Knife dimensions: 6 in. long x 5/8 in. high x 1/8 in. thick - precise sizing allows these blades to serve as direct replacements in compatible planer and jointer machines, simplifying the knife-changing process.
• High-quality surface finish - the combination of sharp HSS edges and precision grinding means the knives produce a refined, flat surface on planed boards, reducing the need for heavy sanding afterward.

Why This Product

• Woodworkers who surface both softwoods and hardwoods - including wet hardwood species - benefit from HSS knives with 13% tungsten content, which maintain a sharper edge longer across varied moisture levels and wood densities compared to standard steel blades.
• Replacing all 3 knives as a matched set from a single package ensures cutter head balance is maintained, which directly affects the smoothness of the planed surface and the stability of the machine during use.
• The 6 in. x 5/8 in. x 1/8 in. knife profile is a widely used dimension in stationary jointer and planer machines, making this set a practical replacement option for machines that accept this standard knife size.
• Precision grinding from fine European high-speed steel means each knife arrives with a consistent, ready-to-use edge - reducing setup time and delivering quality results from the first pass.
