Freud C140 30" (L) High Speed Steel Industrial Planer and Jointer Knives — engineered for precision and endurance in the toughest production environments. If your shop runs wide boards and tight tolerances, these knives are built to deliver repeatable, professional finishes day after day.

Designed from premium High Speed Steel stock, these industrial blades resist wear under heavy stock removal, extending edge life and reducing downtime. Each knife ships pre-ground to a razor-sharp edge, so you can install and cut with minimal setup while achieving a super smooth surface from the very first pass.

• Premium High Speed Steel stock for superior wear resistance and longer edge life during high-volume planing and jointing.
• Pre-ground razor edge means faster installation and consistently clean, tear-out-free surfaces right out of the box.
• 30" length (L) tailored for standard industrial planers and jointers that use the C140 format, ensuring an even, controlled cut across wide boards.
• Designed for Freud/Diablo C140 systems for a precise fit and dependable alignment, minimizing setup time and downtime.
• Versatile across species and tasks — ideal for production cabinetry, furniture, and millwork where a smooth, professional finish matters.

Use cases and benefits:

• Replace dull blades to restore cutting performance and surface quality in high-volume milling runs.
• Maintain consistent planed thickness and jointer finishes on boards of varying hardness.
• Reduce machine chatter and improve feed efficiency thanks to a stable, sharp edge.

Tips for best results:

• Install with proper seating and alignment to prevent skewed cuts—verify the knife sits flush with the cutterhead.
• Store knives clean and dry, and rotate when wear becomes noticeable to preserve even surfaces across boards.
• Pair with a well-tuned planer and jointer to maximize the benefits of the premium HSS edge.
