Lenox 1772964 Bi-metal Hole Saw 3-1/8 in Metal Cutting

Product Description

The LENOX 1772964 is a bi-metal hole saw designed for cutting clean, accurate holes in metal and similar materials. The toothed cutting edge and variable pitch pattern work together to reduce vibration, minimize heat buildup, and extend blade life during repetitive cutting tasks. At 3-1/8 inches in diameter and 1-1/2 inches in cut depth, this saw handles standard trade applications where consistent hole size and depth are critical. The 1/2-inch arbored shank ensures secure attachment to compatible drill arbors. Licensed HVAC techs, plumbers, and electricians reach for this saw when running pipe, conduit, or duct penetrations through metal panels and framing members.

This hole saw suits residential and light commercial trade work where metal penetrations are required. Common applications include cutting holes in electrical enclosures, HVAC sheet metal, plumbing access panels, and structural steel framing. The 3-1/8-inch diameter is a frequently used size for pipe and conduit rough-in work. Its bi-metal construction handles the repeated stress of production cutting without the premature tooth wear common in carbon-steel-only saws.

Key Features

• Bi-metal construction for durability and extended cutting life on metal substrates
• 3-1/8-inch saw diameter for standard pipe, conduit, and panel penetrations
• 1-1/2-inch cutting depth accommodates typical panel and framing stock thickness
• Variable pitch tooth pattern reduces vibration and heat during cuts
• Toothed cutting edge delivers clean hole profiles with minimal burring
• 1/2-inch arbored shank provides positive engagement with standard drill arbors

Compatibility

Designed for use with standard 1/2-inch hole saw arbors. Intended for cutting metal materials per the manufacturer application rating.

Installation Notes

Installation of this hole saw is performed by licensed electricians, plumbers, and HVAC technicians during rough-in work. Ensure the drill and arbor are powered off and fully stopped before mounting or removing the saw. Use appropriate cutting fluid or lubricant when cutting harder metals to reduce heat and extend tooth life. Follow applicable NEC, IPC, or IFGC clearance and penetration requirements when cutting holes in structural or fire-rated assemblies.
