Lenox 1772729 Hole Saw 1-1/2 in Bi-metal Variable Pitch

Product Description

The LENOX 1772729 is a bi-metal hole saw designed for cutting through metal in trade and industrial applications. It features a 1-1/2 inch saw diameter and a 1-9/16 inch cutting depth, making it suitable for standard-depth penetrations through sheet metal, conduit knockout work, pipe notching, and similar tasks. The toothed cutting edge runs a variable pitch pattern, which reduces vibration and helps prevent tooth stripping on harder metals. The arbored design with a 1/4 inch shank diameter provides a secure connection to a standard hole saw arbor or mandrel. Electricians, plumbers, HVAC technicians, and general contractors commonly use this saw for rough-in work and panel cutouts.

This hole saw fits into everyday trade workflows where a reliable, repeatable cut through metal is required. It is well suited for residential and light commercial installations, including electrical box knockouts, pipe penetrations through metal studs, and conduit entry points through metal enclosures. The 1-1/2 inch diameter is a commonly called-for size in mechanical and electrical rough-in, and the 1-9/16 inch cut depth accommodates typical wall and enclosure thicknesses encountered in the field.

Installation Notes

This hole saw is installed by trade professionals including electricians, plumbers, and HVAC technicians during rough-in and service work. Always de-energize electrical panels and shut off water or gas supply lines before cutting near live systems. Use the appropriate arbor and ensure the shank is fully seated and secured before operation. Eye protection and work gloves are standard PPE when operating hole saws on metal surfaces.
