1/4″ X 3″ 9008/C2 Chamfered Tungsten Carbide Rod by Castlebar

Description

Product Overview

The 1/4″ X 3″ cemented tungsten carbide round rod from Castlebar is engineered to meet the demanding specifications of modern manufacturing and high‑performance tooling. Constructed from a high‑grade 9008/C2 alloy containing 10% cobalt, the rod achieves a Rockwell hardness of HRa 92.0 and a tensile strength exceeding 3500 MPa, making it one of the toughest materials available for precision components. The sub‑micron grain size ensures a uniform microstructure that reduces the risk of micro‑cracking under cyclic loads, while the ground‑polished chamfered surface delivers a maximum roughness of 3.9 μin Ra, providing a near‑mirror finish that minimizes friction and wear in contact applications. Dimensions are tightly controlled with an h6 tolerance of +0/‑0.00035 inches, guaranteeing interchangeability and consistent performance across batches. Packaged in a compact 3.8 × 0.75 × 0.75 in box weighing 1.59 oz, the rod is ready for immediate integration into machining setups, tool inserts, or custom‑fabricated assemblies.

Usage

Designed for a broad spectrum of industrial environments, this tungsten carbide rod excels in applications where extreme hardness, wear resistance, and dimensional stability are critical. In aerospace manufacturing, the rod is used for precision drilling of high‑strength alloys and composite materials, where its polished chamfered edges reduce tool deflection and extend tool life. Automotive engineers rely on the rod for high‑speed machining of engine components, such as valve seats and camshaft bearings, where thermal stability and resistance to abrasive wear are paramount. The rod also serves the metal‑cutting and stamping industries, providing a durable insert for forming operations on hardened steels and exotic alloys. Its compact size makes it suitable for micro‑machining equipment, including CNC micro‑mills and laser‑assisted machining stations, where tight tolerances and surface finish directly impact product quality. End users ranging from tool manufacturers to research laboratories benefit from the rod’s ability to maintain performance under high‑temperature, high‑stress conditions.

FAQ

What does the Grade 9008/C2 designation mean?

Grade 9008/C2 indicates a tungsten carbide composition with 10% cobalt binder, delivering a hardness of HRa 92 and a tensile strength of at least 3500 MPa. This grade is optimized for high‑stress cutting and wear‑resistant applications.

Can the rod be used for high‑speed CNC machining?

Yes, the rod’s polished chamfered surface and stable microstructure make it ideal for high‑speed CNC operations, reducing tool wear and maintaining tight tolerances even at elevated spindle speeds.

Is the product compatible with standard tool holders?

The rod’s 1/4″ diameter conforms to common tool holder specifications, allowing easy installation in most CNC and manual machining setups without the need for custom adapters.

How does the sub‑micron grain size benefit my application?

A sub‑micron grain size creates a more homogeneous material, which improves resistance to crack propagation and enhances overall durability under cyclic loading.

What warranty or support does Castlebar provide?

Castlebar offers a limited warranty covering material defects and provides access to expert technical assistance for product selection, machining parameters, and troubleshooting.
