Lenox 1772966 Bi-metal Hole Saw 3.25 in Metal Cutting

Product Description

The LENOX 1772966 is a bi-metal hole saw designed for cutting through metal in mechanical, HVAC, plumbing, and electrical trade applications. It measures 3.25 inches in diameter with a cutting depth of 1.5625 inches, making it suited for punching clean holes through sheet metal, conduit boxes, ductwork panels, and similar materials. The toothed cutting edge follows a variable pitch pattern, which reduces vibration and binding during cuts. The arbored design includes a 0.25-inch shank for secure chuck engagement. Licensed tradespeople and experienced installers reach for this saw when drilling access holes in metal enclosures and housings.

This hole saw is intended for metal material applications across residential and commercial job sites. It fits common scenarios in HVAC duct penetrations, electrical panel and junction box knockouts, plumbing rough-in through metal framing, and similar trade tasks. The 3-inch pipe tap compatibility makes it directly relevant for tradespeople sizing holes for standard pipe pass-through work. Its compact arbored profile suits both handheld drills and drill press setups.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with rotary cutting tools and applicable safety codes. Secure the workpiece fully before cutting to prevent movement. Use appropriate cutting fluid or lubricant when drilling through heavier gauge metal stock to extend blade life. Inspect the arbor and shank for wear or damage before each use and replace if the cutting edge shows signs of stripping or tooth loss.
