The Ridgid 32975 Model 103 close-quarters tubing cutter can be adjusted to cut tubing with an outside diameter of 1/8 inch up to 5/8 inch (3 mm to 16 mm). Designed specifically for working in restricted spaces, the Model 103 cutter is ideal for small-diameter tubing made of hard and soft copper, brass, aluminum, and plastic. The strong yet lightweight slide and wheel housing along with a large, knurled feed-screw knob make it easy to control the cutting pressure to ensure clean cuts. The Ridgid 32975 Model 103 close-quarters tubing cutter comes with one standard cutter wheel (the replacement wheel is Ridgid Catalog Number 33185, Model E-3469). Ridgid's high-quality tools and accessories help you finish your jobs more quickly and reliably.
