Drum Chipper Knives and Disc Chipper Knives

 

 

Drum chippers and disc chippers both process wood into chips, but their knife design and working requirements are not always the same. The knife size, mounting holes, cutting angle and material should match the machine structure.

 

This page is for customers who know their chipper type and need knives for a drum chipper, disc chipper or similar industrial wood chipping equipment. Instead of choosing only by blade length, it is better to check how the knife is installed and how the machine cuts the wood.

 

We produce drum chipper knives and disc chipper knives according to machine requirement, existing blade, drawing or confirmed specification.

 

 

A drum chipper usually works with knives mounted on a rotating drum. Customers often care about impact resistance, stable feeding and long working hours.

 

A disc chipper uses knives mounted on a rotating disc. Customers usually pay more attention to cutting angle, knife position and chip size consistency.

Drum chipper knives often work under heavier impact. The knife must fit the drum correctly and keep stable performance during continuous cutting.

 

• Strong knife body for heavy-duty cutting
• Accurate mounting holes
• Stable cutting edge
• Suitable toughness for impact load
• Consistent size for repeated replacement

 

If the knife does not match the drum design, it may affect feeding, chip quality or machine balance.

 

 

Disc chipper knives need accurate cutting position and angle. A small difference in knife size or angle can affect the final chip size and cutting smoothness.

 

• Correct blade length and thickness
• Accurate hole position
• Consistent cutting angle
• Smooth cutting surface
• Stable chip size

 

For disc chipper users, clear drawings or old blade samples are very helpful before production.

 

 

Chipper Type	Main Focus
Drum Chipper	Impact resistance, stable feeding, heavy-duty cutting
Disc Chipper	Cutting angle, chip size consistency, accurate mounting
Industrial Chipper	Long working hours and reliable repeat supply
Biomass Chipper	Wear resistance and practical cost control
Wood Recycling Chipper	Toughness for mixed or recycled material

 

 

 

This information helps us check whether the knife should focus more on toughness, wear resistance, sharpness or repeat production stability.

 

 

Drum and disc chipper knives are used in many wood processing lines.

 

• Forestry wood chipping
• Biomass fuel preparation
• Pulp wood chip production
• Sawmill waste processing
• Wood recycling
• Panel board raw material preparation
• Industrial wood chip production

 

 

Before shipment, we check the blade size, mounting holes, cutting edge, hardness and surface condition according to the confirmed specification.

 

The knives are packed to protect the cutting edge during transportation. For regular orders, packaging, labeling and part number marking can be discussed.

 

 

• Are drum chipper knives and disc chipper knives the same?

 

No. Drum chippers and disc chippers use different cutting structures. Their knives may differ in size, hole pattern, cutting angle and working load.

 

• Can you make knives if I only know the chipper type?

 

The chipper type is useful, but we still need blade size, hole position, angle and machine information. Photos, drawings or old samples help confirm the details.

 

• Which material should I choose?

 

It depends on the wood material, chipper type, cutting load and current blade problem. Clean logs, hardwood, biomass material and recycled wood may need different material choices.

 

 

If you need knives for a drum chipper or disc chipper, send us your chipper type, machine model, blade size, drawing or old knife photos. We can check the specification and suggest a suitable production option.
