Greenlee 50191624 Bi-Metal Hole Saw, Variable Pitch, 2-1/2 IN

Greenlee 50191624 Bi-Metal Hole Saw, Variable Pitch, 2-1/2 IN

The Greenlee 50191624 Bi-Metal Hole Saw is a variable pitch cutting tool engineered for fast, clean boring in electrical and mechanical installations. Built with a 2-1/2 IN hole diameter and a 1-5/8 IN cutting size, this hole saw is sized for 2.000 IN conduit and a matching 2.000 IN pipe tap application, making it a go-to choice for electricians and contractors who need precise, repeatable cuts through metal and other dense materials during rough-in and panel work. The bi-metal construction combines flexibility and durability, allowing the saw to resist breakage while maintaining a sharp cutting edge through demanding jobsite use. With a variable pitch tooth design, the 50191624 distributes cutting load evenly across the blade, reducing vibration, extending tool life, and delivering smoother hole edges compared to fixed-pitch alternatives. Compact at 4.900 IN length, 2.400 IN width, and 1.850 IN height, this hole saw is easy to store, transport, and maneuver in tight panel and enclosure spaces, and it is manufactured in the US to Greenlee's professional-grade standards.
