Extra-Long Hard Jaws Allow Machining of Smaller Diameter Materials

Extra-long hard jaws from Dillon Manufacturing provide the extended reach that the company says allows the machining of smaller diameters, giving shops more versatility to handle a wider range of projects. 

The jaws are compatible with 8” to 15” power chucks, and are designed to maximize the potential of big-bore chucks, offering exceptional center reach and versatility. Regardless of size, each Dillon extra-length hard jaw is manufactured from robust 8620 steel for long-lasting performance. Multiple lengths are available for each chuck size, allowing customizable options to suit specific machining needs. The company added that they also allow faster setups and thus reduce downtime to improve overall shop efficiency and productivity. Dillon extra-long hard jaws are an ideal solution for handling challenging small-diameter part machining using a big bore chuck.

In addition to extra-long hard jaws, Dillon manufactures a full line of workholdig solutions which are available through their nationwide network of industrial distributors with industry leading lead times. Application engineers are available to assist with product selection.
