Lenox 2011448CHC Hole Saw 3 in Carbide Tipped Sheet Metal

Product Description

The LENOX 2011448CHC is a carbide-tipped hole saw designed for cutting through sheet metal with a toothed cutting edge. It has a 3-inch saw diameter and a 1/2-inch cutting depth, making it a compact but capable tool for punching clean, round openings in metal panels, enclosures, and ductwork. The carbide-tipped construction provides durability and edge retention during repetitive cuts on harder materials. This hole saw is used by HVAC technicians, electricians, and plumbers who regularly need precise, round cutouts in metal substrates. It is sold as a single unit and does not include an arbor.

This hole saw is suited for sheet metal applications common in HVAC duct fabrication, electrical panel work, and plumbing rough-in tasks. The 3-inch diameter is a frequently used size for conduit knockouts, duct penetrations, and access openings in metal enclosures. Its non-arbored design means it requires a separately purchased arbor compatible with standard hole saw mandrels. It is appropriate for use in both residential and light commercial trade work where metal penetrations are required.

Installation Notes

Installation of this hole saw requires a compatible arbor and a drill capable of handling hole saw attachments. Always secure the workpiece firmly before cutting to prevent movement. Wear appropriate eye and hand protection when cutting metal. Follow applicable workplace safety standards and ensure the drill is set to an appropriate speed for metal cutting to avoid overheating the carbide tip.
