EFCUT Replacement Blades for C30 Series Wood Chippers - Pack of 4 HSS Knives, Fits C30/C30 Mini

EFCUT replacement blades are precision high-speed steel cutting knives made to restore peak shredding performance in C30, C30 Mini, C30 Lite and 3-in-1 EFCUT chippers (pack of 4).

When your wood chipper’s cutting performance drops, swapping in a fresh set of blades gets you back to fast, clean chipping without buying a new machine. These knives are manufactured from heavy-duty high-speed steel to resist wear, accept repeated sharpening and fit machines rated for up to 3 inches (not for 4-inch C40 models). The dimensions and hole pattern match the original C30-series specifications so installation is straightforward.

What machines are these blades designed for?

These knives are specifically engineered for EFCUT’s C30 family: the full-size C30, C30 Mini, C30 Lite and the 3-in-1 wood chipper/shredder/mulcher models that accept 3-inch diameter branches. They are not compatible with the larger 4-inch C40 chippers.

• Compatible: EFCUT C30, C30 Mini, C30 Lite, 3-in-1 models (3" max).
• Not compatible: C40 (4" capacity) or unrelated brands/models.
• Direct-fit bolt hole spacing and size for simple replacement.

How durable and serviceable are these high-speed steel knives?

Forged from heavy-duty high-speed steel, the blades are built to withstand repeated impact and abrasion typical of wood-chipping work. The material holds an edge longer than standard carbon steel and can be sharpened multiple times to extend service life.

• Material: high-speed steel for improved wear resistance.
• Sharpenable design lets you refresh edges instead of replacing blades.
• Rigid 5mm thickness resists bending under load.

What are the exact blade dimensions and mounting details?

Each knife measures 105 mm long by 35 mm wide and 5 mm thick, with the mounting hole spaced to match the EFCUT rotor pattern. The holes are sized to fit standard EFCUT mounting hardware, making swaps fast and accurate.

• Length: 4.13 inches (105 mm); width: 1.38 inches (35 mm); thickness: 0.20 inches (5 mm).
• Hole spacing: 40 mm (1.575 in); hole diameter: 8 mm (0.315 in).
• Sold as a set of 4 knives—enough to refresh multiple positions on the rotor.

How do I install and maintain these replacement knives?

Installation follows standard blade-replacement steps for EFCUT chippers: disconnect power, access the rotor, unbolt the worn knife, position the new blade, and torque bolts to spec. Routine inspection and seasonal sharpening keep the tips cutting efficiently and reduce strain on the machine.

• Safety first: power off and secure the rotor before servicing.
• Use correct bolts and torque settings per your machine manual.
• Clean debris and inspect blades regularly; sharpen when edges dull.

Who is this for: These EFCUT replacement blades are meant for home gardeners, landscapers, and property managers who already own an EFCUT C30-series chipper and want a reliable, serviceable way to restore cutting power. If you need durable, replaceable knives with exact-fit mounting for 3-inch-capacity EFCUT machines, this pack of four offers a practical and economical solution backed by EFCUT customer support.
