Milwaukee 49-56-9646 – Frequently Asked Questions

1) How deep will the Milwaukee Hole Dozer 4-1/8 inch hole saw cut?
Cutting depth is 1-5/8 inches, which covers a single layer of drywall, sheathing, plywood, or sheet metal in one pass. For stacked material or thick timber deeper than 1-5/8 inches you will have to cut from both sides or step the plug out.
2) Can the Hole Dozer bi-metal hole saw cut through metal as well as wood?
Yes. The bi-metal Hole Dozer is a general purpose saw rated for thick and thin metals, aluminum, drywall, plastics, wood, and wood with nails in it, so an electrician boring a panel knockout and a remodeler cutting nail-embedded studs can use the same saw.
3) What sizes does the Milwaukee Hole Dozer come in around 4 inches?
Two closely spaced large diameters: 4-1/8 inch, part number 49-56-9646, and 4-1/4 inch, part number 49-56-9647. Pick by the finished hole you need, not by the conduit or fitting label, since the saw cuts to its stated diameter.
4) Does the 49-56-9646 hole saw include an arbor and pilot bit?
The 49-56-9646 is sold as the hole saw cup only. You supply the arbor and pilot drill. At 4-1/8 inches this is a large-diameter cup, so it takes a large arbor rather than the small-diameter type, and the cup is designed with increased pilot visibility so you can line the pilot up on your mark.
5) How do you get the slug out of a 4-1/8 inch hole saw without wrecking it?
The Hole Dozer uses All Access Slots, a plug-jack slot design that lets you get a screwdriver or pry bar in behind the slug from more than one angle for leverage. That matters at 4-1/8 inches, where a plug of plywood or double-layer drywall wedges hard in the cup.
6) Will a 3.5 TPI hole saw work for sheet metal, or is that tooth count too coarse?
3.5 TPI is the coarse tooth count Milwaukee specifies on the large Hole Dozer sizes, and the saw is rated for both thick and thin metals as well as aluminum. On thin sheet, clamp the work and keep speed low so the coarse teeth do not grab and tear the edge.
7) Why does the Hole Dozer bind less in deep cuts than a plain bi-metal hole saw?
The cup carries a thermoset coating that cuts friction and drag against the kerf wall. Less drag means less heat and less current draw, which is the difference between finishing a 4-1/8 inch hole on one battery charge and stalling partway through on a cordless drill.
8) Is the Milwaukee 49-56-9646 hole saw made in the USA?
Yes, the 4-1/8 inch Hole Dozer is US made, which matters on public and institutional jobs where domestic sourcing is part of the purchase requirement.
