The case sucks
As much as these are you’d think Milwaukee would make it so the saws stay in place but instead they just bang around everywhere damaging the blades and there’s room for one more paddle bit They couldn’t add one more or at least 2 different sizes these are amazing blades but the cheaper set you get a pack out case which I’m assuming is much better but the more expensive and bigger set you get a crappy plastic box That should be the opposite

    Teeth worn down flat drilling first hole
    The 2 inch hole saw teeth worn down within minutes of starting a hole in mild steel. This was the first time I used any of the Dozer hole saws in my 28 piece kit. I bought this kit to replace cheaper bits that are junk and wear out quickly. Unfortunately it appears that my dozer bits may be junk to. I bought this kit because of the wide selection of hole saws and the ease of the interchangeable arbors and pilot bits. However if the blades cannot even drill one hole before wearing the teeth out the set is useless.

      This review is for Milwaukee BIG HAWG hole saw set Product 49-56-9290. This hole saw set includes a tough, high-density polyethylene case with steel hinge pins and handy sliding latch. It includes three 4-1/2 inch long carbide-tipped pilot bits, a hex wrench, a sturdy arbor and six heavy-duty hole saws with three carbide teeth each. The saw teeth are a relatively wide 3/16-inch. So far, I have used this set to rough-in PVC five waste pipe plumbing systems and to install clothes dryer exhaust venting for several dryers, primarily cutting through fir wood framing lumber and through drywall, plywood flooring, plywood sheathing and cement board siding. The cutting performance of this product is remarkable. I consistently cut through 1-1/2 inch thick framing members with the 4-1/4 inch saw in under 40 seconds with no jams over signs of overheating. In fact the saw for each operation (with both larger and smaller hole saws) was no more than just warm when cutting through 2-inch dimension lumber and through cement board siding. These saws perform admirably in cement board siding, the cutting operation each time completed in less than a half minute for the largest of the saws in this set. The saws all have 1/2-inch wide, 1-7/8-inch deep relief slots that contribute to easy release of the cut core and effective chip release for cooling during cutting. The cutting depth for all of the saws is just short of 2-1/2 inches, about a half inch greater than other hole saws I own. These saws work so well that I am inclined to reach for them first when I must saw cut holes. Since the largest of the saws in this set is too small for rough-in plumbing using 4-inch PVC piping, I purchased a BIG HAWG hole saw in the 4-5/8 inch size. This is a great product from my perspective because of its performance and durability.

      There's lots to like about the Milwaukee BIG HAWG Carbide Hole Saw 10-Piece Kit. Let's start with the basics: These are rough-in hole saws, not the product to drill that expensive door for a lockset. Having been stuck a few times to use a finish hole saw for a rough-in application, I've burned them up in hard wood, destroyed the teeth hitting a nail that wasn't suppose to be there, and pushed hard in awkward situations that froze the saw to the arbor (drill end). That's a waste of time and tool. This kit will solve just about any hole size needed during rough-in. What they don't tell you ... is how to connect the hole saw to the arbor (drill and drill end assembly). Milwaukee got it right! To make this go quick (if you haven't used this type of arbor before), this is the trick. First, back off the nut just till it engages its rear most position (towards the drill). Second, pull back the round ribbed part that has two metal bumps or protrusions and hold it near the nut, so that you can screw the hole saw onto the threads of the arbor. Screw the hole saw on the arbor to just about where the two metal bumps (that insert into the holes on the hole saw) touch; stop. Third, align the two bumps to the hole saw and push this unit so that the two metal bumps go into the hole saw. Lastly, tighten the nut to hold everything in place. This is the best attachment method I've seen. I still have an old hole saw where the screw-in arbor is permanently attached. The wood was really tough and it torqued up on me. The result is they are fused together. To successfully separate the two would damage the hole saw, taking it out of round - so what's the point? Here, THAT WILL NOT HAPPEN WITH THIS DESIGN. Did I saw that if you spend some serious dollars on this kit, you get a decent storage box? Well, you do. Great job, Milwaukee. Oh yeah - are the hole saws any good? They are spectacular. The quickly chew their way through wood, which is exactly what you hoped this kit would do. Even better is that they spit out the wood out the back as they cut, and as a result the inner core is small and quickly falls away. You don't get the wood plug stuck in the hole saw. The entire kit is money well spent.

      This quality hole saw kit supplies many of the sizes you may need. For me this set represents a transition from a few low quality hole saws to a high grade set that is likely to meet most of my hole sawing needs in the future. From 3/4" to 1 1/2" the set includes all sizes in 1/8" increments. The larger sizes might seem to be chosen at random up to the maximum diameter of 4 3/4". For example there is a 4 1/8" saw but not a 4" one. Knowing how well Milwaukee designs its products, I am sure there is a good reason for their choice. They will have picked the sizes that are most useful to most users. These blades cut quickly and accurately, even the larger sizes, and after one large project the blades show no signs of wear. They will see a lot of use in the future.

      This is the best Hole Saw Kit I have ever seen or owned! There are 22 hole saws, 3 quick-change arbors and 3 thick core pilot bits. A very well designed, portable, sturdy case is included to keep all parts very organized. All saws are labeled with their size for easy locating. So far I have used this hole saw to connect rain barrels to the down spouts from my gutters. I used the 2 1/8" size to drill a hole into the metal downspout and the 1 1/2" size hole saw to drill into the plastic rain barrel. Set up was easy and fast and the saws cut through the metal and plastic so quickly with no effort. The holes they made were smooth with no rough edges to sand down. The slots on the sides of the saws made it easy to get the cut metal and plastic centers out too. I finished my project in a matter of minutes. This kit is constructed of high quality materials, is well-made and performs at top capacity just like all the Milwaukee tools I own! Furthermore, it's made in the USA! Great product and so many sizes of saws.!
