Chipper Knives, Reversible Knives and Shredder Knives
Chipper knives and shredder knives are robust industrial cutting tools used to reduce wood, green waste, plastics and other materials into smaller pieces. They are designed to withstand high mechanical loads, impact forces and abrasive materials in demanding shredding and chipping applications.
The design and material of the knife depend on the machine, material being processed and required cutting performance.
Chipper Knives
Chipper knives are used in wood chippers and other processing machines to cut branches, logs, wood residues, green waste and similar materials into chips.
Depending on the machine and application, chipper knives can be manufactured with different dimensions, cutting angles and mounting configurations.
Chipper knives are commonly used in:

• Forestry and timber processing
• Wood processing
• Biomass processing
• Green waste processing
• Recycling
• Waste management

The cutting geometry is selected according to the material and machine requirements.
Reversible Knives
Reversible knives are designed with two usable cutting edges. When one cutting edge becomes worn, the knife can be turned over and used with the second edge.
This design can extend the operating life of the knife and reduce maintenance and replacement costs. Reversible knives are commonly used in shredders, chippers and other industrial processing machines.
Depending on the application, reversible knives can be manufactured in different shapes, dimensions and materials.
Shredder Knives
Shredder knives are used in industrial shredding machines to process materials such as:

• Plastics
• Rubber
• Wood
• Packaging materials
• Industrial waste
• Household and commercial waste
• Recycling materials

Shredder knives can be designed with different cutting geometries, including straight, angled or specially shaped cutting edges, depending on the rotor, counter knife and material being processed.
The interaction between the rotor knives and stationary counter knives is important for achieving the required shredding performance and particle size.
Materials for Chipper and Shredder Knives
Chipper and shredder knives are exposed to significant mechanical and abrasive loads. The material must therefore provide a suitable combination of hardness, toughness and wear resistance.
Depending on the application, knives can be manufactured from suitable tool steels and other wear-resistant materials. Material selection depends on the processed material, machine type, operating conditions and required service life.
Grinding and Regrinding
Regular inspection and professional grinding and regrinding of chipper and shredder knives can restore the cutting edge and maintain consistent processing performance.
Regrinding can extend the service life of the knives and reduce replacement costs. For reversible knives, both cutting edges can be used before replacement is required.
Custom Chipper and Shredder Knives
We manufacture custom chipper knives, reversible knives and shredder knives according to customer drawings, specifications or samples.
Dimensions, cutting angles, mounting holes, knife geometry and material can be adapted to the respective machine and application.
If you require chipper knives, reversible knives or shredder knives, send us your drawing, sample or technical specifications. We manufacture precision industrial knives for demanding shredding, recycling and material-processing applications.
