3mm x 38mm Polished Chamfered Tungsten Carbide Rod – Grade 9008/C2

Description

Product Overview

The 3mm x 38mm cemented tungsten carbide round rod from Castlebar is engineered to meet the demanding standards of modern industrial machining. Constructed from high‑grade 9008/C2 material, the rod features a sub‑micron grain size that provides exceptional hardness of HRa 92.0 and a tensile strength of at least 3500 MPa. The ground polished chamfered finish, with a maximum surface roughness of 0.1 μm Ra, reduces friction and extends tool life in abrasive environments. Dimensional tolerance follows the h6 standard, guaranteeing a diameter variation of +0 /-0.006 mm, which translates to reliable repeatability in precision applications. The rod’s compact size and lightweight design—measuring 1.5 × 0.12 × 0.12 inches and weighing only 0.16 oz—make it easy to integrate into a variety of setups, from CNC machines to custom tooling assemblies.

Beyond its mechanical properties, the rod benefits from a cemented matrix that combines 10% cobalt binder with tungsten carbide particles, delivering a balanced blend of toughness and wear resistance. This composition ensures that the rod can withstand high impact loads while maintaining dimensional stability under thermal cycling. The product is not discontinued and remains available for immediate shipment, with a proven track record reflected in its ranking as #57 in Tungsten Rods on Amazon. Whether you are a small‑scale workshop or a large manufacturing facility, this rod offers the performance and reliability required for critical operations.

Usage

Designed for high‑precision machining, the 3mm x 38mm tungsten carbide rod excels in applications such as micro‑drilling, fine‑detail milling, and precision tooling where tight tolerances are essential. Its polished chamfered edges reduce chip adhesion and facilitate smoother material removal, making it ideal for aerospace component fabrication, medical device manufacturing, and electronics assembly where surface finish directly impacts product quality. The rod’s robust hardness allows it to cut through hardened steels, nickel‑based alloys, and composite materials without rapid wear, extending tool change intervals and reducing downtime.

In addition to machining, the rod is suitable for use in wear‑resistant fixtures, custom jigs, and high‑temperature environments where conventional steel components would deform. Its compact dimensions enable integration into confined spaces, such as the spindle of a high‑speed rotary tool or the tip of a specialized probe. Users can also employ the rod as a reference standard for calibrating measurement equipment due to its precise dimensional stability. The product’s versatility makes it a valuable asset for engineers, toolmakers, and research laboratories seeking consistent performance across a range of operational conditions.
