Lenox 1772949 Bi-metal Hole Saw 3-5/8 Inches Metal

Product Description

The LENOX 1772949 is a bi-metal hole saw designed for cutting through metal and similar materials in trade and industrial applications. With a 3-5/8 inch saw diameter and a 1-9/16 inch cutting depth, it handles a range of penetration and rough-in tasks common in plumbing, HVAC, and electrical work. The toothed cutting edge uses a variable pitch pattern, which reduces vibration and helps prevent tooth stripout in harder materials. At 0.915 pounds, the saw pairs with a 1/4 inch shank arbor for secure chuck mounting on standard drills and drill presses. Licensed tradespeople and experienced contractors are the typical end users for this tool.

This hole saw is suited for cutting metal pipe openings, conduit knockouts, and similar penetrations in sheet metal, steel plate, and related ferrous materials. The 3 inch pipe size compatibility makes it a practical choice when cutting openings for 3 inch pipe rough-ins in mechanical and plumbing installations. The arbored design means it accepts a standard arbor for repeatable, centered cuts in production or service environments.

Installation Notes

Installation and use of this hole saw should be performed by qualified tradespeople familiar with rotary cutting tools and safe drilling practices. Always de-energize electrical systems and isolate any live lines before cutting penetrations in panels or enclosures. Use appropriate cutting fluid or lubricant when cutting ferrous metals to extend blade life and reduce heat buildup. Secure the workpiece firmly before beginning the cut to prevent movement and tool kickback.
