Klein Tools 31932 Bi-metal Hole Saw 2 Inch

Product Description

The KLEIN TOOLS 31932 is a 2-inch bi-metal hole saw designed for cutting clean, consistent holes in wood, plastic, and light-gauge metal. Bi-metal construction combines a hardened high-speed steel cutting edge with a flexible alloy steel body, giving the saw durability under repeated use without premature tooth breakout. At 0.13 pounds, the 31932 is a compact, single-purpose cutting tool suited for electricians, plumbers, and HVAC technicians who need precise round penetrations through framing, panels, and enclosures.

The 31932 is well-suited for residential and light commercial trade work where consistent 2-inch hole diameters are required. Common applications include drilling through wood studs and plates for conduit or pipe runs, cutting access holes in enclosures, and penetrating thin metal panels. It is the type of tool found on service vans and in tool bags across electrical, plumbing, and HVAC trades where hole saws see frequent, varied use.

Key Features

• 2-inch cutting diameter for standard trade penetrations
• Bi-metal construction with high-speed steel teeth for extended tooth life
• Flexible alloy steel body resists cracking and tooth breakout under load
• Compact and lightweight at 0.13 pounds for easy one-handed use
• Compatible with standard arbor/mandrel setups used across common drill configurations

Compatibility

Designed as an OEM-style replacement or direct-use hole saw for standard bi-metal hole saw arbors common in residential and light commercial trade applications.

Installation Notes

Hole saws of this type are installed by electricians, plumbers, and HVAC technicians using a standard hole saw arbor and corded or cordless drill. Before use, confirm the arbor is fully seated and the pilot bit is secure. Always wear eye protection when cutting, and reduce feed pressure when breaking through the back face of the material to prevent grab or binding. Follow applicable NEC or IPC requirements when sizing penetrations for conduit or pipe.
