The RIDGID® Model HC-450 is engineered for continuous 1⁄4″ (6 mm) to 4 3⁄4″ (120 mm) hole cutting in and up to 8″ (203 mm) diameter steel unpressurized pipe. The built-in level ensures line up for multiple holes when branching lines using Mechanical T®, Vic-O-Let™ fittings or welded saddles. The HC-450 is ideal for mechanical, industrial maintenance and fire protection contractors since it cuts holes into a wide variety of pipe materials. No off-the-shelf drill-based hole cutter compares in performance or durability to the rugged purposed-built Model 450.
