Model HC450
Owner's Manual Parts List Where To Buy Service Center Print Page
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’s, Vic-O-Lets 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. The HC450 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.
