Product Description
Milwaukee 1-3/4 in. Carbide Grit Hole Saw with Carbide Pilot Bit
Model Number: 49-56-0437
The Milwaukee 49-56-0437 is a 1-3/4 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 1-3/4 in. bore is specified for the pipe stub-out, conduit sleeve, or fixture 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 1-3/4 in. diameter serves medium plumbing stub-out holes through tiled walls, conduit penetrations through tile surfaces, and specific fixture mounting holes where this bore falls between the common adjacent tile hole sizes for the fitting or hardware being installed.
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 in heat-sensitive glazed tile, and suppressing respirable silica dust. Slow, steady feed pressure without forcing prevents tile face spalling at the cut perimeter. See Milwaukee's complete carbide grit hole saw lineup for all available diameters for tile and hard surface hole sawing.
