Product Description
Milwaukee 1-1/4 in. Carbide Grit Hole Saw with Carbide Pilot Bit
Model Number: 49-56-0422
The Milwaukee 49-56-0422 is a 1-1/4 in. Carbide Grit Hole Saw with an included Carbide Pilot Bit — an abrasive grit hole saw for cutting clean, accurate holes through ceramic tile, porcelain tile, natural stone, and fiberglass where the 1-1/4 in. bore is specified for the plumbing fitting, conduit penetration, or fixture hardware being installed through a tiled or stone surface. The carbide grit rim grinds through hard, brittle tile and stone by abrasive action — preventing the chipping, cracking, and perimeter fracture at the cut edge that toothed hole saws cause when used in brittle glazed ceramic and porcelain tile. The 1-1/4 in. diameter serves standard plumbing pipe stub-outs through tile walls, small conduit penetrations through tile surfaces, and specific fixture hardware mounting holes where this bore matches the pipe or fitting being installed through the finished tile surface.
The included carbide pilot bit provides the centering function that positions and holds the hole saw at the exact marked hole center during initial cutting engagement on smooth, slippery tile surfaces. Wet cutting with water or drill cooling spray is strongly recommended — extending carbide grit service life, reducing thermal cracking risk in heat-sensitive glazed tile, and suppressing respirable silica dust generated during drilling. Slow, steady feed pressure without forcing the saw into the material maintains the abrasive cutting action and prevents the brittle tile face from spalling at the cut perimeter during the drilling operation.
