Lenox 1773006 Bi-metal Hole Saw 4.5 in Metal Cutting

Product Description

The LENOX 1773006 is a bi-metal hole saw designed for cutting through metal and similar tough materials in trade and industrial applications. With a 4.5-inch saw diameter and a 1.5-inch cutting depth, it handles a wide range of penetration tasks common in HVAC, plumbing, and electrical rough-in work. The toothed cutting edge uses a variable pitch pattern to reduce vibration and binding during cuts. The 0.5-inch arbored shank mounts to standard hole saw arbors, making it compatible with most professional drill setups already on the job site.

This hole saw is suited for residential and commercial installation work where clean, accurately sized holes are required in metal panels, conduit knockout applications, sheet metal ductwork, or mechanical room penetrations. HVAC technicians, plumbers, and electricians regularly use this size when running pipe, conduit, or duct through metal framing or equipment enclosures. The 4.5-inch diameter is a common size for larger conduit runs and duct collars.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary cutting tools and applicable safety practices. Always secure the workpiece before cutting and use appropriate eye and hand protection. Disconnect or lock out power to any panel or enclosure before cutting into it. Use a cutting fluid or lubricant when cutting thicker metal stock to extend blade life and improve cut quality.
