The RIDGID Model HC450 is engineered for continuous 1?4" to 4-3?4" hole cutting in and up to 8" 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. Dual-side feed handles and switches provide easier operation from any angle. In addition, the HC450’s heavy-duty chuck accommodates 1?8" to 5?8" arbors.
