For professional woodshops that demand edge-to-edge precision, the Freud C330 4-3/8" High Speed Steel Industrial Planer and Jointer Knives are engineered to keep your production running smoothly. Built by Freud/Diablo, these knives pair industrial-grade durability with a finish that minimizes post-cut work and maximizes throughput.

• Premium High Speed Steel stock delivers exceptional wear resistance, extending service life and maintaining a sharp edge through heavy use.
• Pre-ground razor edge out of the box ensures an immediate, ultra-smooth cut, reducing tear-out and the need for extensive initial tuning.
• Optimized geometry for planing and jointing provides clean faces, flat edges, and consistent take-off across a variety of stock types—from soft pine to hard maple.
• 4-3/8" length (L) designed to fit industrial planers and jointers configured for this standard size, making replacement straightforward and reliable.
• Industrial-grade durability holds up under high-volume production, with edge geometry that supports precise shaving without gouging or chatter.

Why this matters in real-world workflows

• Consistent results across boards—you’ll notice uniform thickness and smooth faces from pass to pass, which speeds up finishing and assembly.
• Reduced downtime—with a razor-sharp edge ready to go, you can push through more stock between sharpenings, keeping your shop momentum intact.
• Versatility across species—whether you’re surfacing softwood or milling denser hardwoods, the C330 knives maintain stability and control for reliable cuts.

Ideal for

• Cabinetmakers and custom shop professionals who run high-output planing and jointing operations.
• Woodworkers upgrading from standard blades to industrial-grade HSS for longer life and cleaner finishes.
• Producers who value precise edge quality to reduce downstream sanding and finishing time.

Care and practical tips

• Handle knives with care to preserve the pre-ground edge; avoid overheating during any re-sharpening or grinding—use appropriate sharpening equipment and procedures to maintain geometry.
• Store in a clean, dry environment and inspect edge geometry before installation to ensure proper seating and performance.
• When replacing, verify compatibility with your equipment’s knife slots and keep the same orientation to preserve cut quality.
