Product Description
Milwaukee 1-1/8 in. Carbide Grit Hole Saw with Carbide Pilot Bit
Model Number: 49-56-0417
The Milwaukee 49-56-0417 is a 1-1/8 in. Carbide Grit Hole Saw with an included Carbide Pilot Bit — an abrasive grit hole saw for cutting clean holes through ceramic tile, porcelain tile, natural stone, and fiberglass where the 1-1/8 in. bore is specified for the fitting, fixture, or hardware being installed through the hard tiled surface. The carbide grit rim grinds through hard, brittle tile materials by abrasive action rather than tooth-shearing — avoiding the chipping, cracking, and perimeter fracture that conventional toothed hole saws cause in brittle glazed ceramic and porcelain tile. The 1-1/8 in. diameter is used for small plumbing stub-outs through tile walls, specific faucet and fixture supply entry holes, and conduit penetrations through tile where this bore size matches the fitting specification.
The included carbide pilot bit provides the centering guidance that keeps the hole saw on the marked center during the initial abrasive cutting engagement on smooth, slippery tile surfaces. Wet cutting with water or drill cooling spray is strongly recommended — water cooling extends carbide grit service life, reduces thermal cracking risk in heat-sensitive glazed tile, and suppresses respirable silica dust throughout the drilling operation. Slow, steady feed pressure without excessive force maintains the abrasive cutting action and prevents overloading the brittle tile face at the cut perimeter. The carbide grit specification is designed for hard tile and stone — not for standard wood or metal hole sawing applications where conventional bi-metal hole saws are the appropriate tool.
See Milwaukee's complete carbide grit hole saw lineup for all available diameters and for carbide tipped saws for non-tile hard material applications.
