Milwaukee 49-56-9609 – Frequently Asked Questions
1) How thick a material can the HOLE DOZER hole saw cut through in one pass?
Cutting depth is 1-5/8 inches, so it will pass through in a single plunge anything up to that thickness: stacked plywood, single or doubled-up studs and plates at nominal wall thicknesses, drywall, and sheet metal. Anything deeper than 1-5/8 inches has to be cut from both faces or stepped with a longer-reach saw.
2) Do I need to buy a mandrel and pilot bit separately for the HOLE DOZER hole saw?
Yes. The HOLE DOZER is sold as the hole saw cup only, by diameter, so you need an arbor with a pilot drill to run it. One arbor covers a range of cup sizes, so most electricians carry a small and a large arbor and swap cups.
3) Which HOLE DOZER size do I need for 1/2 inch and 3/4 inch EMT conduit?
For a clean pass-through hole, 1/2 inch EMT needs roughly a 1 inch bore and 3/4 inch EMT roughly 1-1/4 inch, which are the 49-56-9609 and 49-56-9613 cups. Size up one step if you are sleeving or need pull clearance. Both are within the 1-5/8 inch cutting depth, so a single plate or stud goes in one pass.
4) Will a Milwaukee HOLE DOZER hole saw cut through wood with nails in it?
Yes. The bi-metal tooth construction is rated for wood with nails, along with thick and thin metals, aluminum, drywall, plastics and plain wood. That makes it the right choice for remodel and retrofit drilling where you cannot see what is behind the surface, rather than a wood-only carbide or self-feed bit.
5) How do you get the slug out of a HOLE DOZER hole saw without prying it apart?
The cup has All Access slots, Milwaukee's Plug Jack design, cut into the side so you can get a screwdriver or punch on the plug from more than one angle and lever it out. That is the practical difference from a plain slotted cup when you are running dozens of holes for conduit or cable and cannot stop to dig each core out.
6) What is the biggest HOLE DOZER size, and will it work for a recessed can or a 4 inch vent?
4 inches is the largest, part number 49-56-9645. With a 1-5/8 inch cutting depth it will pass a single layer of drywall, sheathing or a plate in one go, which covers most recessed fixture and small vent openings. Diameters above 4 inches call for a different tool, such as a large-diameter carbide-tooth saw or an adjustable cutter.
7) Is this hole saw aggressive enough to run on a cordless drill without killing the battery?
It is built for cordless. The 3.5 TPI tooth design takes a coarser bite for faster cutting, and the thermoset coating on the cup cuts friction and drag in the kerf, which is what drains a battery on deep or metal cuts. Coarse pitch like this is best kept to wood, plastics and thicker metal; very thin sheet metal cuts cleaner with a fine-pitch saw.
8) Can I hit my mark accurately with this hole saw, or do I need to center punch first?
The cup is built with increased pilot visibility so you can see the pilot bit against your layout mark as you start the hole, which is the main thing that keeps a hole saw from walking. On metal a center punch still helps, but on wood and drywall the sight line is enough to place the hole off a pencil mark.
9) Are Milwaukee HOLE DOZER hole saws made in the USA?
Yes, the HOLE DOZER bi-metal hole saws are made in the USA. That matters on public and institutional work where domestic sourcing is written into the purchase terms.
