Industrial shredder knives

One shredder knife is not suitable for every material and machine. Shredding, pre-shredding and granulation should be assessed as distinct applications, with machine design and feed material considered together. Select a model or share a drawing of the existing knife.

PRODUCT SELECTION GUIDE

Selecting shredder knives for the material and machine

The catalog includes different knife groups for metal, wood, plastics and rubber shredding. Begin a manufacturing enquiry by describing the feed material and whether the machine uses a single-shaft or twin-shaft arrangement.

Distinguish a single component from an assembled set

Cutting-element shape, mounting faces and position within the set depend on the machine arrangement. Single-shaft and twin-shaft knives are not interchangeable simply because they look similar. Show component quantities and layout when requesting a set.

Pre-shredding or the next granulation stage?

Pre-shredding bulky material and subsequent granulation are different cutting tasks. Share the feed form, current knife code and damage condition. Together with the technical drawing, these details support assessment of geometry and material.

Before requesting a quote

Can I request knives for a Zato machine?

See the twin-shaft knife and assembled-set page for Zato machines. Exact compatibility is confirmed against your machine model and approved drawing; the brand reference does not establish fit for every model.

Is replacing only the broken element enough?

Show its position and the rest of the set. Dimensions and arrangement must be checked between the replacement and retained components; a photograph alone may not be sufficient.

Which hardness or steel should I order?

Describe the feed material and machine conditions first. Catalog material and hardness values belong to the stated model; they must not be applied collectively to every shredder application.

Choose industrial knives by application

Compare cutting tools manufactured by Universal Bıçak by their task. Product pages include actual photographs, catalog information and the technical details needed for an enquiry.

Discuss your requirements ↗

From technical enquiry to manufacturing scope

01

Share your requirements

Describe the machine, material being cut, knife dimensions and quantity. Attach a drawing or a photo of the existing knife if available.

02

Assess the technical scope

Consider the product group, mounting details, material and operating conditions together. Clarify any missing information during the technical discussion.

03

Define the work stages

Define the manufacturing, machining or maintenance steps needed. Discuss dimensions, inspection and documentation requirements within the quotation scope.

04

Plan inspection and the next step

Clarify the agreed acceptance criteria and delivery scope. For technical questions during use, contact us with the product code and application details.
