Product Description
Milwaukee 3/4 in. Carbide Grit Hole Saw with Carbide Pilot Bit
Model Number: 49-56-0405
The Milwaukee 49-56-0405 is a 3/4 in. Carbide Grit Hole Saw with an included Carbide Pilot Bit — a small-diameter abrasive grit hole saw for cutting precise holes through ceramic tile, porcelain tile, natural stone, and fiberglass where the 3/4 in. bore is required for pipe or conduit stub-outs, specific fixture mounting, and small penetrations through tiled surfaces. The electrodeposited tungsten carbide grit rim grinds through hard, brittle tile and stone materials by abrasive action rather than the tooth-shearing method of conventional hole saws — preventing the chipping, cracking, and perimeter fracture at the cut edge that toothed hole saws cause in brittle glazed ceramic and porcelain tile. The 3/4 in. diameter serves small plumbing stub-outs through tile walls, specific conduit penetrations, and faucet supply line entries through tile backsplashes and shower walls where this compact bore size is specified.
The included carbide pilot bit provides the essential centering function that keeps the hole saw accurately positioned at the marked hole center during the initial cutting engagement on smooth, hard tile surfaces — without the pilot bit, the abrasive rim has no centering mechanism and would wander before establishing the circular cutting path. Wet cutting with water or a drill cooling spray is strongly recommended for all carbide grit tile hole sawing — water cooling extends the carbide grit's service life, reduces the thermal cracking risk in heat-sensitive glazed ceramic and porcelain, and suppresses respirable silica dust. Slow, steady feed pressure prevents overloading the brittle tile at the cut perimeter.
