Milwaukee 49-56-0158 – Frequently Asked Questions

1) What cutting diameters does the Milwaukee HOLE DOZER bi-metal hole saw come in?
Two sizes are offered: 2-5/8 inch (Milwaukee 49-56-0158) and 4-1/2 inch (Milwaukee 49-56-0233). The 2-5/8 inch is the common size for round box and recessed fixture openings, while the 4-1/2 inch takes larger-format holes in a single pass.
2) Do I need to buy an arbor and pilot bit separately for a Milwaukee 49-56-0233 hole saw?
Yes. The 49-56-0233 is the 4-1/2 inch cup only. Hole saws in this size class mount to a separate arbor that carries the pilot drill and the shank for your drill chuck, so plan on having a large-diameter arbor on hand. Order it with the saw if you don't already run one.
3) Which HOLE DOZER size should I use for cutting in round electrical boxes versus a larger equipment opening?
For round box and fixture cutouts the 2-5/8 inch (49-56-0158) is the size electricians reach for. When you're passing larger conduit, equipment, or making an HVAC or plumbing rough-in opening, step up to the 4-1/2 inch (49-56-0233), which completes the bigger hole in one pass instead of stepping up through sizes.
4) Is the HOLE DOZER hole saw carbide or bi-metal, and what does that mean for cutting metal?
It is bi-metal construction, not carbide-tipped. Bi-metal hole saws have a high-speed steel cutting edge welded to a tougher backing, so they handle wood and sheet metal like electrical enclosures and light-gauge duct. For abrasive materials such as masonry, tile, or cast iron, a bi-metal saw is the wrong tool and a carbide or diamond hole saw is what you want.
5) Can I run a 4-1/2 inch bi-metal hole saw in a cordless drill/driver?
A 4-1/2 inch cup takes real torque. Use a drill with a side handle, a low-speed setting, and a clutch or mechanical stop, and keep the speed down so the teeth clear chips instead of loading up. A compact drill/driver will stall and can twist out of your hands at that diameter.
6) What materials will the Milwaukee HOLE DOZER bi-metal hole saw cut on a jobsite?
It is used for electrical box and conduit knockouts, HVAC ductwork and equipment installs, plumbing rough-in, cabinetry and fixture work, and general construction and remodeling. That covers wood, plywood, drywall, plastics, and sheet metal such as enclosures and duct.
