Cutter Discs and Claw Knives
Disc or claw-style cutters engage bulky feed and need the correct profile, thickness, bore and cutting direction for the shaft position.
Double-Shaft Shredder Components
Double-Shaft Shredder Knives
Replacement cutter discs, claw knives and matched wear components for twin-shaft shredders.
A reliable replacement starts with the shaft layout, cutter stack and working material—not a tooth count or size copied from an unrelated machine. Send the machine model, an old-part photo or drawing, and the required quantity for a fit review.

Double-shaft knives work as part of a cutter stack
The cutter profile, bore, thickness, spacer arrangement, shaft layout and cutting chamber must work together.
Shafts, Bores and Spacers
The shaft section, keyway, spacer sequence and cutter stack determine how the parts sit and rotate together.
Clearance and Wear Surfaces
Cutters must work within the chamber and around related wear parts; similar-looking discs are not automatically interchangeable.
Product types for replacement and custom supply
Choose a starting point below, then confirm the exact fit against the machine, cutter stack or approved drawing.
Cutter Discs
Disc-style moving cutters for twin-shaft assemblies, supplied after the outer profile, thickness, bore and stack position are confirmed.
Claw or Hook Knives
Toothed, claw-style or hooked forms for a defined cutting arrangement. The profile must follow the original machine or an agreed redesign.
Spacer Rings
Spacers help establish cutter spacing and stack position. Their bore, outside diameter and thickness belong to the shaft assembly.
Shaft-Matched Cutter Sets
Matched cutter sets can be reviewed with the shaft section, keyway and spacer sequence when a complete replacement is needed.
Counter or Fixed Elements
Where the machine uses a fixed cutting element, its seat and clearance should be checked with the moving cutter set.
Drawing-Based Knife Production
We can review a drawing, worn sample or clear photos before confirming material, geometry, quantity and production details.
Double-shaft cutter disc details
These close-up views show the visible stack, bore and cutting-edge details we review when matching a replacement cutter.
The images show product features, not a universal size or compatibility standard. Exact geometry, bore, thickness and shaft position still need to be confirmed against the machine, drawing or sample.
Match the cutter focus to the working condition
Double-shaft cutters are selected around the feed form, resistance, contamination, wrapping risk and reduction target.
Bulky Plastic and Drums
Containers, drums, pipes and rigid plastic where grab-and-tear engagement and primary reduction matter.
Rubber, Tires and Cables
Elastic or heavy feed where torque demand, wrapping risk and cutter toughness need review.
Wood, Pallets and Biomass
Large wood waste and selected biomass where feed size, moisture and downstream handling affect the cutter choice.
E-Waste and Mixed Waste
Mixed industrial feed with changing composition, where fit, wear, impact and contamination should be confirmed together.
What we need to match a replacement cutter
These are the useful inputs for a real quotation. They are a checklist—not a universal double-shaft specification.
01
Machine
Brand, model, shaft layout and any machine or rotor identification.
02
Part Position
Cutter disc, claw knife, spacer, shaft component or fixed cutting element.
03
Geometry
Outside profile, thickness, bore, teeth or claws and any drawing reference.
04
Stack and Mounting
Keyway, shaft section, spacer sequence, fixing direction and cutter orientation.
05
Working Duty
Material, largest feed piece, contamination, wrapping risk and reduction target.
06
Order Details
Required quantity, delivery location and whether a matched cutter stack is needed.
Key cutter and stack details to confirm
These fields affect fit and performance, but their final values belong to the selected machine and cutter system.
Teeth, Claws and Cutting Direction
Confirm whether the cutter uses a disc, tooth, claw or hook profile, and how it is oriented on each shaft.
Outside Diameter and Thickness
Record the outside profile and thickness together with the working position; a single dimension cannot define the replacement.
Bore, Keyway and Shaft Section
The internal bore and keyway must match the shaft. Confirm the shaft section rather than assuming a standard bore.
Spacers, Sequence and Clearance
Stack order and spacing influence engagement and clearance. Review the complete assembly when parts are worn or missing.
Parameter boundary: no universal tooth count, cutter size, hardness, throughput or machine compatibility is claimed on this general page. Final values are confirmed from the machine, drawing, sample and working condition.
Materials and manufacturing follow the actual cutter duty
Wear resistance matters, but toughness, impact, contamination and the shaft arrangement also affect the practical material choice.
Tool-Steel Options
Tool-steel options such as D2, DC53 or other agreed grades may be considered after the feed, impact and wear condition are reviewed.
Wear and Toughness
A harder cutter is not automatically better. The selected material should balance edge stability, resistance to chipping and expected maintenance.
Inspection Against Approved Details
Inspection is based on the confirmed drawing, sample or machine information, including the agreed geometry, mounting and finish requirements.
From an old cutter or drawing to a matched replacement
A short, practical workflow keeps the quotation focused and reduces the risk of mixing parts from different shaft systems.
Step 01 / Review
Send the machine and part information
Provide the model, shaft layout, part position, dimensions, photos, drawing and working material. A photo of the complete cutter stack is especially useful.
Step 02 / Confirm
Check profile, stack and quantity
We review the cutter geometry, bore, keyway, spacer arrangement and replacement scope before a quotation is finalized.
Step 03 / Produce and Inspect
Make against the approved reference
Production and inspection follow the confirmed drawing, sample or written requirements, with matched components reviewed together when needed.
Double-Shaft Shredder Knife Questions
Short answers to the questions that usually affect fit, cutter selection and quotation.
Are double-shaft cutter discs interchangeable between machines?
Usually not. Bore, keyway, cutter thickness, shaft section, spacer arrangement and cutting chamber clearance can all be different. Confirm the machine and cutter position before ordering.
Can you match a cutter without an OEM drawing?
Often yes. A clear photo, worn sample, machine model and key dimensions can provide a starting point. Final confirmation still depends on the shaft and stack details.
What should I measure on an old cutter disc?
Record the outside profile, thickness, internal bore, keyway or locking detail, tooth or claw form, and the position in the cutter stack. Photos of both faces are helpful.
Should I replace the whole cutter stack together?
Not always. If the wear, spacing or shaft condition is uncertain, reviewing the cutters, spacers and shaft arrangement together can reduce clearance and installation errors.
Is a higher tooth count always better?
No. Cutter profile and tooth count affect engagement, resistance and material control, but the correct choice depends on the machine, feed form, reduction duty and shaft layout.
Is D2 or DC53 better for double-shaft cutters?
Neither is universally better. The practical choice depends on abrasion, impact, contamination, cutter geometry and the existing machine setup. We review the duty before recommending a material.
Can you supply spacers or shaft-related wear parts?
Tell us the complete replacement scope. We can review related parts when the machine model, drawing, sample or clear assembly photos confirm how they fit the cutter stack.
