Lenox 1772956 Hole Saw 2-5/8 in Bi-metal Variable Pitch

Product Description

The LENOX 1772956 is a bi-metal hole saw designed for cutting through metal and other hard materials in trade and industrial applications. With a 2-5/8 inch saw diameter and a 1-1/2 inch cutting depth, this hole saw handles common penetration tasks in HVAC, plumbing, and electrical rough-in work. The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, delivering durability under repeated use. A variable pitch tooth pattern reduces vibration and improves chip clearance during cuts. The arbored design accepts a 1/2 inch shank arbor for compatibility with standard drill chucks and hole saw mandrels.

This hole saw is suited for residential and light commercial trade work where 2-5/8 inch holes are required — typical applications include conduit knockouts, pipe penetrations through studs or sheet metal, and access openings in ductwork or enclosures. It is commonly used by HVAC technicians, plumbers, and electricians during rough-in and service work. The toothed cutting edge performs on mild steel, sheet metal, and similar materials where a clean, accurate hole is required.

Key Features

• 2-5/8 inch saw diameter for standard trade penetration sizes
• 1-1/2 inch cutting depth accommodates typical material thicknesses
• Bi-metal construction for extended tooth life on metal applications

Compatibility

Designed for use with standard 1/2 inch arbor hole saw mandrels. Suitable for cutting metal and similar materials; confirm mandrel and drill compatibility before use.

Installation Notes

Installation of this hole saw should be performed by a qualified tradesperson following applicable safety practices. Secure the arbor firmly into the drill chuck before use and verify the mandrel is rated for the saw diameter. Eye protection and appropriate PPE are required when cutting metal. Allow the saw to cool between cuts to preserve tooth life and prevent heat damage to the bi-metal body.
