Lenox 1772945 Bi-metal Hole Saw 3-3/8 in Metal Cutting

Product Description

The LENOX 1772945 is a bi-metal hole saw designed for cutting through metal in trade and industrial applications. It features a 3-3/8 inch saw diameter and a 1-1/2 inch cutting depth, making it suitable for drilling clean, accurate holes in sheet metal, steel, and similar materials. The toothed cutting edge uses a variable pitch pattern that reduces vibration and helps prevent tooth stripout under load. The 1/2 inch shank with arbor mount accepts standard arbors found on most hole saw drivers. HVAC technicians, electricians, plumbers, and general contractors use this saw for knocking holes in metal enclosures, panels, conduit boxes, and structural members during rough-in and installation work.

This hole saw is built for metal cutting applications in both residential and commercial settings. Common uses include cutting access holes in electrical panels, HVAC ductwork, junction boxes, and metal studs. The bi-metal construction handles the heat and stress of repeated metal-cutting cycles better than carbon steel alternatives. It is sold individually and is ready to pair with a compatible arbor for immediate use in standard drills and drill presses.

Designed for use with standard 1/2 inch hole saw arbors. Suitable as a replacement or additional hole saw for trade professionals working with metal cutting applications in HVAC, electrical, and plumbing installations.

Installation Notes

Install a compatible arbor before mounting the saw in a drill or drill press. Secure the workpiece before cutting to prevent movement and reduce the risk of binding. Always wear eye protection and appropriate PPE when operating hole saws on metal. Allow the saw to cool between cuts to preserve tooth life and bi-metal integrity.
