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

Used this for outside high hats and inside high hats. Works perfectly. Great buy.

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.

This huge hole saw works fine in a drill press when you clamp your material down. Using this with a portable drill is another matter entirely. The blade is too coarse to cut smoothly and will catch and try to break your wrist. If you attempt it, use a drill with a clutch and go slow. I have only used it a few times so can’t comment on durability, however I would purchase it again.

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 a pc case a few years ago with horrible air flow, now that Ive upgraded my parts I need more air. This put a hole right where I wanted it

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 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.

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!

Pleased with the quality of the item. The threaded/pin-type arbor is essentially identical to those Ive purchased from Morse, Lennox, Milwaukee etc. They all have threads that do not run all the way to the back plate which means that when you screw the arbor down to contact the back of the hole saw, few threads are left engaging with the hole saw. If the pins back out due to vibration etc, it is easy to strip the threads. I wish the manufacturers would figure out how to thread the arbor all the way down to the back plate. I put a thin fiber washer with holes drilled out for the pins on first, screw down the arbor and then twist a rubber band around the hexagonal shaft and knurled pin adjusting knob to keep everything in place...

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.
