Product Description
Milwaukee 2-1/4 in. Carbide Grit Hole Saw with Carbide Pilot Bit
Model Number: 49-56-0449
The Milwaukee 49-56-0449 is a 2-1/4 in. Carbide Grit Hole Saw with an included Carbide Pilot Bit — an abrasive grit hole saw for cutting accurate holes through ceramic tile, porcelain tile, natural stone, and fiberglass where the 2-1/4 in. bore is specified for the plumbing fitting, pipe stub-out, or hardware being installed through a tiled surface. The carbide grit rim grinds through hard, brittle tile and stone by abrasive action — preventing the chipping, cracking, and perimeter fracture that conventional toothed hole saws cause in glazed ceramic and porcelain tile. The 2-1/4 in. diameter serves medium-to-large plumbing stub-out holes through tiled walls, specific conduit penetrations, and hardware mounting holes where this bore falls between adjacent standard tile hole sizes for the specific pipe or fitting being installed through the finished tile surface. The included carbide pilot bit provides accurate centering on smooth tile surfaces where the abrasive rim has no self-centering mechanism without the pilot.
Wet cutting with water is strongly recommended throughout all carbide grit tile hole sawing — extending carbide grit service life, reducing thermal cracking risk in heat-sensitive glazed tile, and suppressing respirable silica dust. Slow, steady feed pressure without forcing prevents tile face spalling at the cut perimeter in both ceramic and porcelain tile. See Milwaukee's complete carbide grit hole saw lineup for all available diameters for tile and hard surface hole sawing applications.
