Tosa Tool now offers the “Add Bushings” option for your modular plates. Our Bushings are wear resistant steel and hardened to Rockwell C 58, precision ground, and they are press-fit into the dowel positions in your modular plate. This adds considerable cost but insures durability and proper bore fit. We also offer kits to install bushings into holes that have worn over time. If you need perfect bores and ultimate durability no matter what steel you use, this is the correct option for you.
