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

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!

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.

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.

Worked great for 5” Halo Old Work Can lights.

Worked well, used for installation of 4 recessed lights. Seems pretty well constructed.

put in holes in ceiling for canless can lights. half the ceiling was drywall the other 3/4 inch knotty pine. after 10 holes still sharp and easy to use. I attached mine to a 1/2 inch hammer drill with a side handle for extra stabillity, no problem.

Works well for cutting 5” discs out of 1/4” plywood. The instructions say to run it at 100 RPM but my drill press’s slowest speed is 680 RPM. I cut 16 discs so far with this bit and it did great and still cuts like a new bit. For the price this bit paid for itself already in just the time it’s saved me. Would definitely recommend for lighter duty cutting/drilling jobs.

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!

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.

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
