Lenox 1772780 Bi-metal Hole Saw 2-1/16 in Metal Cutting

Product Description

The LENOX 1772780 is a bi-metal hole saw designed for cutting through metal and similar hard materials. It features a 2-1/16 inch saw diameter and a 1-1/2 inch cutting depth, making it suited for a range of trade applications including HVAC, plumbing, and electrical rough-in work. The toothed cutting edge with a variable pitch pattern improves chip clearance and reduces binding during cuts. A 1/2 inch arbored shank provides a secure, positive connection to standard drill arbors. This saw is installed and used by licensed tradespeople who need a reliable, repeatable hole size in sheet metal, conduit boxes, and similar substrates.

The LENOX 1772780 is well suited for residential and light commercial work where consistent 2-1/16 inch holes are required in metal. Typical applications include punching holes in electrical enclosures, HVAC sheet metal panels, and plumbing rough-in scenarios. The variable pitch tooth geometry helps manage heat buildup and extends blade life when working through ferrous and non-ferrous metals. It is sold as a single unit and is ready to mount on a compatible 1/2 inch arbor.

Installation Notes

This hole saw is installed by HVAC technicians, electricians, and plumbers during rough-in and panel work. Before use, secure the workpiece firmly and ensure the drill and arbor are rated for the saw diameter. Allow the saw to reach cutting speed before applying full pressure to the workpiece, and back off periodically to clear chips and reduce heat buildup. Follow applicable safety codes and wear appropriate eye and hand protection during operation.
