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

I used this on a laminated veneer shiplap ceiling where I was making the cuts where the boards butted up to each other. The boards were about 5/8” thick. No issues. You eat a lot of dust but the cuts were perfect and smooth. The 6-3/8” hole was perfect for Torch Light ultra thin recessed lights.

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.

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!

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

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.

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

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.

Needed this to install fans in a partition wall in an electrical enclosure. I usually buy carbide toothed saws. But this worked splendidly. Cut through two plates at once multiple times. And it never overheated and remains sharp.

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!
