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

Inexpensive compared to name brands but worked perfectly for me cutting a half dozen holes through 2 layers of wood (3/4 incl solid cedar plank backed by 3/4 inch plywood sheeting) still looks knew. Needs 1/2 drill for power. As another reviewer pointed out, use an auxiliary drill handle. Hole saws can bind (did it twice) and the drill torque can seriously strain or otherwise damage your wrist. But saw cut clean holes every time

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.

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.

Works well, very sharp.

Make sure you use a drill that has a second handle for support. Go slow and steady pressure to make the hole otherwise it will bind. But after cutting through a tongue n groove ceiling for 6 holes, I will still have use of this holesaw… the one flaw is that the drillbit provided has to be tightened many times throughout use. Overall this was a good buy.

I like the price because it includes the two hole saw but I prefer the ones with a quick release the measure tape is super basic, but definitely it’s worthy the package, definitely not to be used on plaster I use it a couple times on plaster walls but it takes the sharpness from the saw.

Needed to cut some holes for kitchen exhaust pipe, and this worked spectacularly cutting through some pine. But, then I had to cut through the roof, and of course asphalt shingles present a problem. But, that was the last hole so I committed myself. It got through, eventually, but I dont think it liked it. In a couple years when I need to cut another 6 hole Ill give it another try, but he already did his duty so I wont complain if he takes a bit longer.

We got this to help us make corn hole boards. Makes quick work of it! Just attached to a typical cordless drill and went for it. Worked for us!

Worked great for 5” Halo Old Work Can lights.
