Lenox 1772474 Bi-metal Hole Saw 1-3/16 in Metal

Product Description

The LENOX 1772474 is a bi-metal hole saw designed for cutting through metal in trade and industrial applications. It produces a 1-3/16 inch diameter hole and delivers a cutting depth of 1-1/2 inches. The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, giving the saw durability under repeated use. The variable pitch tooth pattern reduces vibration and helps clear chips during the cut. A 1/2 inch arbored shank provides secure mounting in standard drill chucks and arbors used by HVAC technicians, plumbers, and electricians.

This hole saw is suited for residential and commercial trade work where metal penetrations are required. Common applications include cutting holes in electrical enclosures, HVAC equipment cabinets, plumbing access panels, and sheet metal ductwork. The toothed edge cuts cleanly through mild steel and similar metals, making it a practical addition to a service technician's hole saw kit. The arbored design allows quick attachment and removal without specialty tooling.

Installation Notes

Installed by HVAC technicians, electricians, and plumbers during rough-in and service work. Secure the workpiece before drilling and use cutting oil on metal surfaces to extend tooth life and reduce heat buildup. Wear appropriate eye and hand protection when operating hole saws. Disconnect power to any equipment before cutting into enclosures or panels.
