5 inch HSS BI Metal Hole Saw Cutter 1-1/2 Depth with Big Arbor for Wood Metal

Works well, very sharp.

I bought this to put the hole in cornhole board. It cut through great. Glad I had a big drill with side handle to keep it level and from hurting my wrist though.

Kit includes 2 drill bits, 1 for wood & 1 for metal. Fits a 3/8 inch chuck. The box arrived in great condition but the wood drill bit was broken in 2 pieces.

Bought the 5” hole saw to use on 1/2 inch plywood, and in a 2x8 board. Was impressed by the quality, given how inexpensive it was. The arbor is good quality and came with two drill bits, plus a small hex wrench for the set screw. Was very sharp and have a very clean cut. Only needed it for a small job, so can’t speak to how long it will hold up after many uses. But would not hesitate to buy another one if I need a different size in the future.

If you want to cut a hole for a 4” exhaust pipe, then you’ll be wanting a hole slightly bigger than 4”. This will cut that hole, probably. On my house it cut through cement fiber board (Hardie Board) and wood sheathing. You’ll need something different If you’re going through concrete (perhaps obviously). I was pleased with the weight and apparent hardness of the blade. I only had to cut a single vent hole, so I can not speak to long term durability. Here’s a tip if you’re putting in a vent and you’ve not done something like this before: drill a small pilot hole where you want the big hole to be. In my case, I went into the attic and drilled a small hole through the wall where I wanted to vent out. This way I could be sure to cut the hole where I wanted and be confident I wasn’t going to hit a stud, wiring, or some other sort of surprise. Then, make the big cut from the outside so that you get a nice clean edge in your siding. Good luck!

Very sturdy and durable. What youre cutting will get stuck but there are holes to push product out.

I bought this cheap 5 holesaw to cut through a 1 thick piece of steel. Not just any steel, it is 4140- a chromium molybdenum manganese alloy. But wait- not just any 4140, it is hardened 4140, 32 on the rockwell C scale. A lot of 4140 is sold in the annealed state for easier cutting, but then needs to be hardened afterwards to gain the strength benefits of this alloy. I verified the 32Rc myself, cause I believe it matters for what Im making. Anyway, this holesaw cuts it fine. I ran it at about 70 rpm, a little faster than 1 rotation per second. A little less than 100 fpm linear speed. Using a pecking motion, lubrication, allowing chips to clear. Many drill presses and most hand drills just wont go that slow. If you put this in a hand drill and think youre gonna cut even a piece of sheet metal, its going to be hard to control, and if you spin it fast (like the 600 rpm speed that seems slow in your 1/2 drill) you could probably dull this in seconds. That is just the nature of a large diameter cutter like this. If you overspeed it in metal, you WILL ruin it, in seconds. This saw isnt magic metal, and neither is one that costs 3 times as much. This was used in a milling machine..it is rigid, and can go slow. If used to cut a hole in your ceiling for a lamp, you could get away with a lot, none of this applies. The saw wasnt real round...I checked it and improved it a little by hitting with a hammer, checking, hitting, etc. BUT- more expensive brands are no better at all, they are always pretty out of round..unfortunate, but good enough. Tight quality control costs a lot. You want a $150 hole saw thats somewhat better? Ill deal with a cheap one, myself. It is a roughing tool, no more. It pains me to see most drills and holesaws oversped by users who then dull it and blame the tool!

Seems very well made. I had four holes to cut to install a 6” duct for the microwave/ventilation hood to the outside. I was thinking at this price it might not hold up but to my surprise I think it would cut dozens of times before it becomes dull. My cabinet back is plywood and the wall is tongue and groove lumber, and it cut with no problem. You will need a drill with a 1/2 inch chuck then don’t force the cut just let the cutter do the work.

Its actually very hard to find a whole saw that is bigger than 7in in the market. This hole saw not only gives me the capacity of drill big hole at one shot, also generates surprisingly clean edges. I think this is probably due to the sharp teeth and high quality steel that this saw has. A strong buy!

Impressed with the weight and sturdiness of this hole cutter and especially the arbor. The center of the arbor screws on and then two pins extend for steady and secure grip. So far I have used it to cut 3/4 MDF and it zipped right through it. I was surprised how smoothly it cut. Good value for the money.
