Lenox 1772951 Bi-metal Hole Saw 2-1/8 in Metal Cutting

Product Description

The LENOX 1772951 is a bi-metal hole saw designed for cutting through metal in trade and light industrial applications. With a 2-1/8 inch saw diameter and a 1-9/16 inch cutting depth, it handles conduit knockouts, pipe penetrations, sheet metal panels, and similar tasks encountered by electricians, plumbers, and HVAC technicians. The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, delivering durability under the stress of repeated metal cutting. The variable pitch tooth pattern reduces vibration and helps prevent tooth stripping on thin-gauge stock. At 0.445 pounds, it is lightweight enough for single-hand drill operation on a job site.

This hole saw is suited for residential and commercial trade work where clean, accurate holes in metal are required. Common applications include cutting holes in electrical enclosures, HVAC sheet metal ductwork, junction boxes, steel studs, and plumbing plates. The 1/4 inch arbored shank fits standard hole saw mandrels, making it a straightforward addition to an existing hole saw kit. It is sold and packaged as a single unit.

Installation Notes

A licensed electrician, plumber, or HVAC technician typically installs this saw as part of a hole saw mandrel assembly on a variable-speed drill. Always power down and de-energize or isolate any panel, enclosure, or system being worked on before cutting. Use appropriate cutting fluid or lubricant when cutting thicker metal stock to extend tooth life and reduce heat buildup. Wear eye protection and secure the workpiece before beginning the cut.
