Tungsten Carbide Discs

Precision tungsten carbide disc blanks for circular knives, rotary cutters, slitting tools, dies, and custom wear-resistant components.

Precision tungsten carbide disc blanks for circular knives, rotary cutters, slitting tools, dies, and custom wear-resistant components.

Product Overview

Tungsten Carbide Discs are precision wear-resistant blanks and components designed for circular cutting tools, slitting knives, rotary cutters, dies, valve parts, and custom industrial wear applications. Manufactured from cemented tungsten carbide, these discs provide excellent hardness, wear resistance, dimensional stability, and reliable performance in demanding production environments.

Carbide discs are commonly used as semi-finished blanks for further grinding, edge preparation, brazing, or assembly into finished tools and components. Compared with conventional tool steel discs, tungsten carbide discs can maintain working dimensions and wear surfaces for longer periods in abrasive, high-load, and high-cycle applications.

KENIN Carbide manufactures standard and custom tungsten carbide discs according to customer drawings, samples, finished-tool requirements, and operating conditions. Available options include solid carbide discs, center-hole discs, stepped discs, slotted discs, precision-ground discs, polished discs, and other custom circular carbide components.

Applications

Tungsten carbide discs are widely used as blanks or finished wear components in cutting, forming, processing, and industrial machinery applications.

Typical applications include:

Circular knives and slitting knives
Rotary cutting tools
Paper, film, foil, and textile slitting tools
Woodworking and panel-processing tools
Metal processing and strip-cutting tools
Circular saw components
Rotary shear and trimming tools
Stamping and forming die components
Valve parts and flow-control components
Precision wear discs and sealing components
Custom machinery parts
Toolmaking and carbide component manufacturing

Custom Manufacturing

KENIN Carbide manufactures custom tungsten carbide discs according to drawings, samples, finished-tool designs, and working requirements.

Custom options include carbide grade selection, outer diameter, inner diameter, thickness, center hole, stepped structure, chamfers, slots, holes, grooves, edge preparation, tolerance, flatness, parallelism, concentricity, and surface finish.

We can supply carbide disc blanks with machining allowance, precision-ground discs, polished discs, center-hole discs, circular knife blanks, slitting disc blanks, and other non-standard carbide circular components.

For an accurate quotation, please provide the drawing or sample, outer diameter, inner diameter, thickness, required quantity, carbide grade requirement, finished application, tolerance requirements, surface finish requirement, and expected operating conditions.

Frequently Asked Questions

Can tungsten carbide discs be manufactured according to drawings?
Yes. KENIN Carbide can manufacture tungsten carbide discs, circular knife blanks, slitting disc blanks, center-hole discs, rotary cutter blanks, and other custom carbide circular components according to customer drawings, samples, 3D files, or detailed technical requirements. Outer diameter, inner diameter, thickness, slots, holes, steps, edge condition, tolerance, and carbide grade can all be customized.
Can carbide discs be supplied as blanks for further machining?
Yes. Tungsten carbide discs can be supplied as semi-finished blanks with machining allowance for customers who need further grinding, cutting-edge preparation, brazing, drilling, slotting, or assembly into finished tools and components.
Can the diameter, center hole, and thickness be customized?
Yes. Outer diameter, inner diameter, center-hole structure, thickness, stepped geometry, grooves, slots, holes, chamfers, and other functional features can be customized according to the drawing and finished application.
What information is required for a quotation?
Please provide the drawing or sample, outer diameter, inner diameter, thickness, required quantity, finished application, carbide grade requirement, tolerance requirements, surface finish requirement, and any special features such as slots, holes, grooves, steps, or edge geometry.
What are tungsten carbide discs used for?
Tungsten carbide discs are commonly used as blanks or finished components for circular knives, slitting tools, rotary cutters, saw components, die parts, valve parts, wear discs, and other industrial machinery components requiring wear resistance and dimensional stability.
Can carbide discs be precision ground and polished?
Yes. Depending on the drawing and final application, KENIN Carbide can provide as-sintered discs, precision-ground discs, polished discs, lapped surfaces, controlled flatness, and customized edge conditions.
What is the difference between a carbide disc blank and a finished carbide circular knife?
A carbide disc blank is a round carbide component supplied for further machining, grinding, edge preparation, or assembly. A finished carbide circular knife normally has completed cutting-edge geometry, final tolerances, and application-specific finishing for direct use in a cutting system.
