Milwaukee identifies 49-22-4175 as a HOLE DOZER bi-metal hole-saw kit. Hole-saw diameter must follow the pipe, fitting, sleeve and clearance requirement, not the nominal pipe label alone.
Where it fits
It fits wood and metal materials allowed by the maker when the kit contains the exact diameter required. Tile, masonry and some composites need different cutting media.
Purchase and use checks
Check arbor and drill compatibility, inspect both sides for utilities, clamp the work, use the specified speed and let the saw cool. A rough opening still needs fire, air or water sealing appropriate to the assembly.

What to Check on the Product Page
The page details that matter here are not the marketing lines. They are the size count, the cutting style, and whether the kit matches the kind of cleanup the job demands.
A product page that does not show the sizes you actually need is not a good buy, no matter how good the headline sounds. For plumbing fittings, the right kit is the one that matches the openings you will cut this season, not the one that looks complete on paper.
Size the opening from the fitting
Nominal pipe size is not hole diameter. Measure the outside dimension of the fitting, sleeve, escutcheon or required firestop system and follow the installation instructions. Leave only the clearance the assembly needs; an oversized hole is harder to seal and support.
Use the pilot bit to establish location only after checking both sides of the wall or floor. For a finished surface, a backing board and a controlled entry can reduce breakout. Stop the drill if the cup binds, and remove the plug before it overheats the saw.
Bi-metal teeth suit only materials listed by Milwaukee. Masonry, porcelain and abrasive tile need a compatible carbide or diamond cutter and their own dust or cooling method.
