Greenlee 8251 Variable Pitch Bi-Metal Hole Saw

Greenlee 8251 Variable Pitch Bi-Metal Hole Saw

The Greenlee 8251 Variable Pitch Bi-Metal Hole Saw is engineered for electricians, contractors, and tradespeople who need a dependable cutting tool for boring clean, precise holes through a wide range of materials. Built with an extra-tough bi-metal blade made from the highest grade tool steel, this hole saw delivers a deep 1-5/8 In cutting depth, allowing it to cut all the way through standard 2x4 wood studs in a single pass. A steam oxide finish keeps the saw running cooler during extended use, while an extra-thick backplate minimizes vibration for a smoother, more controlled cut every time.

Key Features

• Deep Cutting Depth: 1-5/8 In cutting depth allows the saw to fully penetrate 2x4 wood studs, making it ideal for running conduit, cable, or piping through framing.
• Durable Bi-Metal Construction: The blade is made of extra-tough bi-metal using the highest grade tool steel for long-lasting sharpness and durability under repeated use.
• Cooler-Running Steam Oxide Finish: The steam oxide finish helps the saw run cooler, reducing heat buildup during extended cutting sessions and helping extend blade life.
• Extra-Thick Backplate: A reinforced, extra-thick backplate minimizes vibration during cutting, resulting in smoother, easier, and more accurate holes.
• Multi-Material Versatility: Cuts cleanly through steel, tin, aluminum, fiberglass, wood, and plastic, making it a versatile addition to any electrician's or contractor's toolkit.
