Not what I expected, what was received is not the same as in photo.
Difference, this saw is white. Not an issue.
The teeth of this saw are sharp and strong however, some of the teeth (shown in photos) are not aligned with the other teeth, some bend inward and some outward.
Solid metal unit. Good weight and connects to attachments well and securely.

This is a really strong and accurate hole saw. I paired it with a drill bit on my drill which worked great. It effortlessly cuts through wood with a very clean accurate hole left behind. I also tried it on a light metal and it cut fine but I don't know about a thicker metal. The teeth come super sharp and haven't dulled so far. This is a nice sturdy piece made with good craftsmanship.

The DMS 3/4 in. Bi-Metal Hole Saw with Variable Pitch Teeth from Drill America is made for cutting holes in a variety of materials. The manufacturer touts features like variable-pitched teeth for less vibration and the ability to cut through a 2” x 4” stud with one pass.
I tested this saw using a standard 1/2” threaded arbor with a 1/4” guide bit. The saw blade does not come with an arbor. I tried cutting holes in plywood, a 1-1/2” thick board and a piece of sheet metal. The saw cut through the wooden pieces easily although I would use a different tool if I was cutting 3/4” holes through studs like for running electrical cables for example. I wasn’t able to discern any marked decrease in vibration compared to other hole saws I have used, but perhaps the larger diameter saws would show off this feature better. When I tested cutting a hole in the sheet metal, the saw blade grabbed the material and did not produce an acceptable hole. I suspect it would not do the same thing in thicker metals.
As a tip, when I use a hole saw to cut through wood, I try to cut from both sides. I make the initial hole and drill/saw until I see the guide bit of the mandrel poke through. Then I move to the opposite side and complete the hole. This limits tear-out on when the saw cuts through the backside of the work piece and makes extracting the plug from the hole saw blade simple especially since this manufacturer didn't provide anything innovative for plug removal unlike other brands.
Overall, this hole-cutting saw blade is good but not anything exceptional.

I got this Drill America DMS 7/8' Bi metal hole saw to try it out, It was a couple bucks more then the other name brands at Home depot I was not disappointed it cut right through the wood with the hard metal sharp pitch teeth, Slotted holes on side of hole saw to remove wood plug from inside from inside hole saw, we drill out several hundreds of these pieces of wood to be used for retro earthquake shims with steel bolts going through the holes we cut out in the wood.

This is a pretty impressive hole saw drill bit. It needs the required an arbor in order to be operational. It is a solid tool and I was quite impressed by how fast I was able to drill through a metal sheet (a bit noisy, protect your ears!) It is a solid product. Note that the picture does not automatically represents the bit: mine being a 1inch diameter, looks much narrower. Anyhow, I do recommend this product.
Bought this to cut a hole in a 3/8" steel plate. To my amazement, it did! I know that this produce and other branded hole saws are listed as being made of HSS but I had little confidence that they could cut thru 3/8" plate steel. Was slow going but the teeth still appeared to be sharp afterwards. Care is needed to keep the cutting speed down or you will overheat and damage the tool.
