Dillon Manufacturing Introduces Reversible Hard Jaws for Faster and More Efficient Workholding!
Dillon Manufacturing has expanded its workholding solutions portfolio with the introduction of reversible hard jaws designed to simplify machining setups while improving versatility and productivity. Engineered for both internal diameter (ID) and external diameter (OD) workholding applications, the reversible jaws enable machinists to reduce setup times, increase operational flexibility and maintain secure, accurate part clamping across a wide range of machining operations. The solution is particularly suited for first-operation workholding, where quick changeovers and consistent positioning are essential for maintaining production efficiency.
The reversible hard jaws are designed to hold a specified range of workpiece sizes, allowing manufacturers to perform both ID and OD clamping using a single set of jaws. This dual-purpose functionality reduces the need for multiple jaw sets, minimizing tooling changes and helping machine shops streamline setup procedures. Faster setup times contribute to increased machine utilization and reduced production downtime, making the jaws well suited for high-mix, low-volume manufacturing as well as repetitive production environments.
Manufactured from high-strength 8620 case-hardened steel, the jaws are engineered to deliver long service life and reliable performance under demanding machining conditions. The case-hardening process provides excellent wear resistance while maintaining a tough core that withstands repeated clamping forces and heavy-duty machining operations. This robust construction ensures consistent gripping performance over extended production cycles while reducing maintenance requirements and replacement costs.
To further enhance accuracy and durability, the reversible hard jaws feature precision-ground locating surfaces that ensure repeatable positioning during installation. Accurate jaw location is essential for maintaining concentricity, minimizing runout and achieving consistent machining results. In addition, each jaw is finished with a black oxide coating that provides corrosion resistance, helping protect the components from moisture, coolant exposure and harsh shop environments while extending their operational lifespan.
Recognizing the diverse workholding requirements found across modern machine shops, Dillon Manufacturing offers the reversible hard jaws in multiple mounting configurations to ensure compatibility with virtually all major chuck brands. Available styles include serrated, Acme Key, square key and tongue-and-groove designs, allowing manufacturers to select the configuration that best matches their existing equipment without requiring modifications or additional adapters. This broad compatibility simplifies implementation while providing users with greater flexibility across multiple machining platforms.
The jaws are available in both single-step and two-step configurations to accommodate different workpiece geometries and clamping requirements. Both versions incorporate precision-machined diamond-shaped serrations that provide a secure gripping surface while ensuring accurate workpiece location. The serration design enhances holding force, minimizes the risk of slippage during machining and improves repeatability, enabling manufacturers to maintain consistent dimensional accuracy across production batches.
By combining reversible functionality, durable construction and universal compatibility, Dillon Manufacturing’s reversible hard jaws provide an efficient workholding solution for a wide range of turning and machining applications. Their ability to support both ID and OD clamping while reducing setup times helps manufacturers improve productivity, simplify operations and achieve reliable workpiece positioning throughout the machining process. The result is a versatile workholding solution that supports higher machine utilization, consistent machining accuracy and greater overall manufacturing efficiency.
