The Milwaukee 49-22-4185 HOLE DOZER General Purpose Hole Saw Kit is a 28-piece hole saw kit built for electricians, plumbers, installers, maintenance crews, and general contractors who need one case that handles a wide spread of common hole sizes. This is a hole saw kit designed for general purpose cutting in wood, metal, and plastic. Model Number: 49-22-4185. The big value here is coverage: you get small sizes for hardware and box work, larger sizes for pipe and conduit openings, plus the arbors and pilot bits needed to get started right away.

What makes this kit matter on the job is not just the number of pieces. Milwaukee built these HOLE DOZER bi-metal hole saws around a 3.5 teeth-per-inch design aimed at longer life in metal applications, and the Rip Guard tooth form is meant to hold up better under hard use. That matters when you are cutting repeatedly through mixed materials and do not want to swap out worn saws halfway through rough-in work. Milwaukee also calls out Thermoset Coating to reduce friction and drag, which helps cutting speed and improves efficiency on cordless drills.

Milwaukee's ALL-ACCESS SLOTS are one of the more practical features in this set. Plug removal is one of the most annoying parts of using a hole saw, especially after a run of repeated cuts. These slots are designed to give you better leverage for getting the slug out faster, and they also improve pilot visibility and chip ejection. In plain terms, that means less downtime between holes, easier placement at the start of the cut, and less heat buildup while drilling.

The storage case is not an afterthought. The included hard case uses interchangeable pegs so you can change the layout to fit how you actually work. There is also a removable accessory box for arbors, pilot bits, and small parts, along with reinforced grids on the top and bottom to help keep the saws in place. If you have used kits where everything shifts around in the truck, this is a better setup. The case dimensions are compact enough for shelf or van storage, but it still holds the full range cleanly.

Size coverage is another reason this kit stands out. It includes 22 hole saws ranging from 3/4 inch up to 4-3/4 inch. That spread is useful across electrical rough-in, plumbing penetrations, HVAC work, and general construction tasks where one diameter never does it all. The kit also includes a 3/8 inch hex shank arbor, a 7/16 inch hex shank arbor, a 7/16 inch no-wobble arbor, three 3-1/2 inch pilot bits, and a 1/8 inch hex key. That gives you the core hardware needed to match the saw size to the job without piecing together accessories separately.

Milwaukee lists this as a multi-purpose kit, and the material makeup supports that. The hole saws are bi-metal, and supplementary product data also notes 8% cobalt for better wear resistance. Combined with the tooth design, that makes this set a good fit for users who cut across more than one material in a single day rather than keeping separate specialty kits for every task. It is also made in the USA, which some buyers still care about when they are buying a kit they expect to keep for a long time.

Who should buy it? If you are a pro who needs broad size coverage in one organized case, this kit makes sense. It is especially strong for field work where organization, durability, and fast plug removal save real time. If you only ever cut one or two diameters, a smaller set may be enough. But if your work regularly jumps between conduit, pipe, box openings, and general penetrations, the Milwaukee 49-22-4185 HOLE DOZER General Purpose Hole Saw Kit is the kind of kit that earns its space in the truck.
