Rotor Knives
Rotor knives perform the primary cutting action during material size reduction. Their geometry and hardness influence cutting resistance, energy consumption, throughput and final particle size.
Eurotools supplies different WEIMA® rotor knife configurations, including compact cutting knives and larger rotor knives for specific machine series.
One example from the Eurotools catalogue is a 298 x 60 x 30 mm rotor knife for WEIMA®, manufactured from 1.2379 tool steel with a hardness of 58–60 HRC.
Concave Knives and Cutters
WEIMA® shredders use compact cutting elements in several configurations. Concave knives and cutters are designed to work with the rotor and counter-cutting system and are available in different dimensions.
Typical configurations include:
- 30 x 30 mm concave cutters
- 40 x 40 mm concave knives
- 60 x 60 x 30 mm concave cutting knives
- Machine-specific cutting crowns
For example, Eurotools lists 60 x 60 x 30 mm concave cutting knives for WEIMA® in 1.2379 tool steel with hardness around 58 HRC.
Counter Knives
Counter knives form the stationary cutting edge against which rotor knives operate. Correct clearance and positioning are important for cutting efficiency and stable particle size.
Depending on the machine model, counter knives may differ significantly in:
- Length
- Width
- Thickness
- Mounting hole configuration
- Cutting edge geometry
- Material grade
- Hardness
For WEIMA® WLK machines, Eurotools supplies model-specific counter knives. For example, the catalogue contains a 335 x 113 x 28 mm counter knife for WEIMA® WLK 1500 and a 349 x 105 x 28 mm middle counter knife for WEIMA® WLK.
Stator Knives
Some WEIMA® configurations use long stator knives as part of the stationary cutting system. Their dimensions and left/right configuration must correspond to the machine design.
For the WEIMA® WLK 15TIP, for example, Eurotools lists separate left and right stator knife configurations.
- 705 x 114 x 15 mm stator knife – right
- 775 x 114 x 15 mm stator knife – left
When ordering these components, the correct side and machine configuration should always be verified.
Knife Systems Used in WEIMA® Machinery
WEIMA® shredders use different knife systems depending on the machine series and application. The cutting geometry can therefore not be selected solely according to the WEIMA® brand name.
Common configurations found in the Eurotools catalogue include:
- Rotor knife systems
- Concave cutter systems
- Counter knife systems
- Toothed counter knife systems
- Stator knife systems
- Side counter knife systems
- Cutting crown systems
The interaction between the rotating and stationary cutting components determines the effective cutting gap and influences the required cutting force, material flow and output size.

WEIMA® WLK Knives and Counter Knives
The WLK series includes several machine configurations, which means that replacement knives cannot be selected based on the WLK designation alone.
For example, the Eurotools catalogue contains dedicated parts for WLK 6S, WLK 14, WLK 15TIP and WLK 1500.
For WEIMA® WLK 14, Eurotools lists a 1477 x 123 x 40 mm set of counter knives as well as individual 236 x 123 x 40 mm counter knives for the machine configuration.
For WEIMA® WLK 1500, the catalogue includes model-specific counter knives and compact cutting elements.
This illustrates why the machine model, dimensions and cutting position should be checked before ordering.
WEIMA® FineCut Knife Systems
WEIMA® FineCut machines use a different cutting geometry from larger heavy-duty shredders. Replacement parts must therefore be selected according to the FineCut machine configuration.
Eurotools lists, for example, a 195 x 57 x 38 mm rotor knife for WEIMA® FineCut manufactured from 1.2379 tool steel with a hardness of 58–60 HRC.
The same catalogue family includes machine-specific FineCut knives and side counter knives.
Manufacturing Materials and Hardness
The service life of a WEIMA® knife depends on more than dimensional compatibility. Material grade and heat treatment must also be matched to the application.
Common tool steel solutions used for recycling and shredding knives include:
- 1.2379 tool steel
- 1.2360 tool steel
- Other alloy tool steels according to application requirements
Eurotools catalogue products include WEIMA® knives manufactured from 1.2379 with hardness values such as 58–60 HRC and other material/hardness combinations.
Higher hardness can improve resistance to abrasive wear, while excessive hardness without sufficient toughness can increase the risk of chipping or fracture in applications with heavy impact or contamination.
Operating Conditions and WEIMA® Knife Wear
Wear rate depends strongly on the processed material and operating conditions.
Important variables include:
- Material composition
- Presence of metal contamination
- Material moisture
- Material density
- Feed rate
- Rotor speed
- Required output particle size
Typical wear mechanisms include:
- Abrasive edge rounding
- Cutting edge deformation
- Impact chipping
- Surface wear
- Mounting surface wear
When the cutting edge becomes excessively rounded, the machine may require greater cutting force and energy to process the same material.
Maintenance Strategy for WEIMA® Wear Parts
Regular inspection of knives and counter knives helps identify wear before it affects machine performance.
Recommended inspection points include:
- Knife cutting edge condition
- Counter knife condition
- Knife-to-counter-knife clearance
- Knife mounting surfaces
- Fastening components
- Rotor condition
- Vibration and abnormal noise
Worn cutting components should be replaced before excessive wear changes the geometry of the cutting system or damages adjacent machine components.
How to Select the Right WEIMA® Knife Configuration
The WEIMA® machine model is the first identification point, but it is not always sufficient to select the correct replacement part.
Before ordering, verify:
- Machine series and model
- Knife position – rotor, stator, counter knife or side knife
- Exact dimensions
- Mounting configuration
- Cutting geometry
- Material grade
- Required hardness
- Processed material
For example, a WEIMA® WLK knife cannot automatically be assumed to fit every WLK model. Model-specific dimensions and cutting-system geometry must be checked.
When the OEM reference number is not available, Eurotools can identify the part using dimensions, technical drawings or photographs of the existing component.
OEM Compatibility and Replacement Solutions
WEIMA® replacement knives can be supplied according to OEM reference information or technical specifications.
Identification can be based on:
- OEM reference number
- WEIMA® machine model
- Technical drawing
- Original part dimensions
- Physical sample
- Photographs
Eurotools also offers alternative material grades and hardness specifications where the application requires a different balance between wear resistance and impact toughness.
Availability and EU Supply
Eurotools operates an EU-based supply program for industrial knives and wear parts. Availability differs according to individual product, specification and production status.
Selected WEIMA® products are available from stock, while other model-specific components are manufactured to order.
For example, the Eurotools catalogue currently lists stock quantities for selected WLK and compact WEIMA® cutting components, while some larger counter knives and stator knives are produced to order.
For current availability and lead time, the exact item number or technical specification should be provided.
Custom Manufacturing and Wear Part Optimization
When a standard replacement configuration is not suitable for the processed material, custom manufacturing can be considered.
Possible engineering variables include:
- Alternative tool steel grades
- Modified hardness
- Different cutting geometries
- Modified dimensions
- Alternative wear protection
Custom production can be based on technical drawings, dimensions, physical samples or analysis of an existing wear part.
How to Request the Correct WEIMA® Spare Parts
To identify the correct WEIMA® knives or wear parts, provide as much of the following information as possible:
- WEIMA® machine model
- Machine serial number, if available
- OEM reference number
- Eurotools item number, if known
- Part dimensions
- Knife position
- Required quantity
- Processed material
- Photographs of the existing part
- Technical drawing, if available
Accurate technical information reduces the risk of supplying an incorrect knife configuration and helps determine the appropriate material, hardness and delivery option.
