Lenox 1772933 Bi-metal Speed Slot Hole Saw 1-3/4 in

Product Description

The LENOX 1772933 is a bi-metal hole saw designed for cutting common construction materials including wood, plastic, and light-gauge metal. Measuring 1-3/4 inches in diameter with a cutting depth of 1-9/16 inches, this saw is built around a proprietary toothform engineered to extend service life in demanding trade applications. The reinforced tooth geometry is designed to absorb impact forces from obstructions and bind-ups, reducing tooth breakage during use. The SPEED SLOT staircase design built into the body allows for fast plug ejection without additional tools. Licensed electricians, plumbers, HVAC installers, and general contractors routinely use hole saws of this type for penetration work.

This hole saw is suited for residential and light commercial construction tasks where repeatable, clean-diameter holes are required. Typical applications include drilling through framing, sheathing, and similar construction substrates for pipe, conduit, or duct penetrations. The 1-3/4 inch diameter makes it a common choice for standard plumbing and electrical rough-in work. It is sold as a single unit per pack.
