About Our Company

Industrial Sales of Oakland Inc. is a proud US manufacturer of quality Collet pads and Collet pad top jaws for the metalworking industry. We are located in the heart of where the industrial revolution started. We are located in Oxford Michigan.

ISO started up in 1983 in dad’s garage. We began by offering machining services to the government, and expanded into the automotive field. In 1985 we began marketing our collet pads through the local tooling houses. As we grew we began to concentrate solely on our product line.   Over the years we have built our company with national distributorships. By 2015 ISO has over 400 distributorships that ship around the World.

Today, ISO not only sells Collet pads and the Collet pad top Jaws, we also can assist you with your special jaw designs. ISO can help with your work holding needs. We also can supply your soft jaws, hard jaws, T-nuts and other chuck related products.

Today once again we are a full service machining company. We have been able to bring in some of our key vendors into our
facility. Now we can have faster turn around time on our products. Also we are able to use their expertise in our machine shop.  By doing this we can offer full machining service. We do detail work, short run and long run production.
