Cutting perfect circles in steel is easy with the HTPPlasma Cutter Circle Cutting attachment. You can adjust the size of the circle you want to cut and choose from 3 different base types to hold the compass in place. The plasma torch guide end is on wheels allowing it to glide over the work. Then, just set the torch in the guide, pull the trigger, and you're cutting perfect circles in seconds. It's really that easy. We proved it!
