Tungsten Carbide Rods

Product Overview

This is a tungsten carbide extension shank designed for use in high-wear or high-precision applications. It is manufactured to customer drawings and can include internal or external threads. The part is pressed and sintered to maintain dimensional stability and is ground to final dimensions. It is suitable for use in tooling, machining, and mechanical assemblies where wear resistance and dimensional integrity are critical.

Key Benefits

Longer service life than steel in abrasive or high-load environments, reducing downtime and replacement frequency
Maintains dimensional stability under high pressure and vibration, ensuring consistent fit and function
Available with internal or external threads to match specific tool or assembly requirements
Made to drawing under OEM and ODM terms, so it integrates directly into existing designs without modification
Samples provided for pre-testing before bulk production, reducing risk of mismatched parts

Problems It Solves

Steel extension shanks wear out quickly when exposed to abrasive materials or high-speed operation, leading to tool failure
Thread mismatch or deformation occurs in standard metal shanks under repeated stress and heat
Lack of availability of custom shanks with specific internal or external thread profiles from standard suppliers
Inconsistent dimensions in off-the-shelf shanks lead to poor fit and reduced tool performance
No sample testing before bulk order leads to risk of incorrect part geometry or material choice

Who It Is For

Tool and die makers producing custom cutting tools with non-standard shank geometries
Machinery manufacturers integrating wear-resistant components into high-duty assemblies
Industrial maintenance teams replacing worn shanks in production equipment
Contract manufacturers sourcing precision carbide parts with custom thread configurations
R&D departments prototyping tooling with high wear resistance and tight tolerance

Application Scenarios

Extension shank in high-speed rotary tools where steel wears quickly under continuous load
Tooling components in CNC machining centers requiring wear-resistant shafts with precise thread fit
Assembly in industrial machinery where vibration and abrasive particles accelerate wear on standard metal parts
Custom tooling for metal cutting, grinding, or drilling applications with non-standard thread profiles
Replacement part for a worn or damaged shank in a specialized tool system

Technical Features

Pressed and sintered from tungsten carbide powder to maintain shape and density
Capable of internal and external thread machining to customer specifications
Ground to final dimensions after sintering to ensure dimensional accuracy
Regular geometry with minimal dimensional variation from the pressed blank
Available in standard grades including YL10.2, YG6, YG8, YG10, YG15, YN6, YN9, selected based on service conditions

Materials and Grades

WC-Co cemented carbide with cobalt content selected for the balance of hardness and toughness required by the application
Lower cobalt grades such as YG6 for maximum wear resistance in clean, high-load service
Higher cobalt grades such as YG15 for applications involving impact or thermal cycling
Grades selected based on fluid, load, temperature, and wear environment

Customisation Options

Manufactured to customer drawings including non-standard and specially shaped shanks
Thread type and profile matched to the application, including internal and external threads
Grade selected based on operating conditions such as load, temperature, and wear environment
Samples produced for pre-testing before bulk release
OEM and ODM services available with full technical support

Manufacturing

How This Part Is Made

Drawing review and grade selection

Powder blending and pressing on imported press

Over-pressure sintering to stabilise density and close porosity

Thread machining and grinding to final dimensions

Dimensional and physical property inspection

Packing and shipping

Quality Control

Physical properties, shape and tolerance are checked before shipping
Every order is tested before bulk production is released
Inspection photographs of the finished order are sent for confirmation before delivery

Use Guide

Send the drawing with the required thread type, pitch, and service conditions so the grade and tolerance can be matched
Order a sample before bulk production to verify fit, thread accuracy, and material performance
Ensure the mating components are compatible with the shank’s hardness and dimensional tolerance
Avoid sudden thermal or mechanical shock to the carbide part during installation or operation
Keep the first sample for comparison when evaluating future batches

Comparison

How It Compares With The Alternatives

Alternative	Trade-off
Steel extension shank	Steel is cheaper and easier to machine, but wears rapidly in abrasive or high-load conditions, leading to shorter tool life and more frequent replacements
Hardened steel with coating	Coating wears through quickly, exposing the base metal which then fails rapidly; solid carbide wears uniformly and consistently
Ceramic extension shank	Ceramic offers high hardness and chemical resistance but is more brittle under impact or shock loading; carbide better withstands dynamic stress

FAQ

Tungsten Carbide Extension Shank FAQ

Are you a trade company or a manufacturer?

A manufacturer. The company has produced tungsten carbide parts for over 15 years and takes on design and processing of carbide products with technical support.

Where is your factory located?

Zhuzhou City, Hunan Province, China, which is the country's tungsten carbide production base.

Can you produce the products according to my own drawing?

Yes. OEM and ODM services are standard. We manufacture to your drawing, including non-standard and specially shaped parts.

Can I get a sample before placing a bulk order?

Yes. Samples are available for pre-testing. Send your drawing and service conditions, and we will provide a quote.

How long does an order take?

Stock items are shipped 3-5 days after payment is received. Customised items are given a delivery time in the quotation.

How do I know the parts were checked before they shipped?

Physical properties, shape and tolerance are inspected before shipping, and detailed inspection photographs of the order are sent for confirmation before delivery.

Which grade should I choose?

It depends on the service conditions. Lower cobalt grades such as YG6 offer better wear resistance in clean abrasive environments; higher cobalt grades such as YG15 are better for impact or shock loading. Send the operating conditions and a grade will be recommended.
