Woodworking Jointer Knife

Woodworking jointer knives are cutting tools used in jointers, which are woodworking machines used to create flat and smooth surfaces on wooden boards. Jointer knives are specifically designed to fit into the cutterhead of a jointer and are responsible for removing material from the surface of the wood.

These knives are typically made of high-speed steel (HSS) or carbide, which are durable materials that can withstand the high-speed rotation of the cutterhead. They are available in various sizes and shapes, depending on the specific jointer model and the desired cutting profile.

The jointer knives are installed in the cutterhead in pairs, with each knife positioned at a slight angle to the other. This arrangement allows for a shearing action that produces a smooth and even cut on the wood surface.

Over time, jointer knives can become dull or damaged due to regular use. When this happens, they need to be sharpened or replaced to maintain the jointer's cutting performance. It is important to regularly inspect and maintain the jointer knives to ensure optimal results and prevent accidents.

In summary, woodworking jointer knives are essential tools used in jointers to create flat and smooth surfaces on wooden boards. They are part of the supply class "Tools And Attachments For Woodworking Machinery" in the supply group "Woodworking Machinery And Equipment."
