The SWAG Plasma Circle Cutter Guide makes cutting perfect circles with your plasma torch quick, repeatable, and precise. Adjustable in 1/2" increments, the large guide cuts circles from 1.0" to 20.5". Laser-etched reference marks at 0.50", 0.75", 1.00", and 1.25" help you dial in the exact radius by combining the marked position with the correct hole placement. Each large hole is spaced 1.00" apart and measures 0.250" in diameter—these can be drilled out if needed to fit larger torch tips. Kit includes one laser-cut circle cutting plate and a brass thumb screw for easy setup.
