Milwaukee 49-56-0023 – Frequently Asked Questions

1) What sizes does the Milwaukee HOLE DOZER bi-metal hole saw come in, and what are the model numbers?
Four diameters: 3/4 inch (49-56-0023), 1-1/8 inch (49-56-0052), 2-3/8 inch (49-56-0142), and 5 inch (49-56-0243). Order by the model number for the diameter you need, since the number is the only thing that differs between them.
2) Will a Milwaukee HOLE DOZER bi-metal hole saw cut steel, or is it wood only?
Bi-metal construction means it cuts metal as well as wood and plastic. The hardened cutting edge handles metal while the flexible steel body resists snapping, which is what separates it from a carbon-steel hole saw limited to wood.
3) Which HOLE DOZER size should I use for electrical box and conduit work?
The 2-3/8 inch (49-56-0142) is the general-purpose jobsite diameter and is called out for electrical box and conduit installation, plumbing access holes, and HVAC duct work. For smaller conduit and cable runs the 3/4 inch (49-56-0023) or 1-1/8 inch (49-56-0052) are the ones to reach for; the 5 inch (49-56-0243) is for large duct and pipe penetrations.
4) Is the 49-56-0142 hole saw a 2-3/8 inch hole or a 2-3/8 inch outside cut?
The 2-3/8 inch figure is the hole saw's cutting diameter, so it produces a 2.375 inch hole. Size it against the finished opening you need, not the pipe or box body.
5) Can I buy just one HOLE DOZER size instead of a whole kit?
Yes, each diameter is sold as an individual hole saw under its own Milwaukee model number, so you can replace a single worn size out of an existing kit rather than buying a new set.
