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

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!

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.

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.

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.

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.

Arrived on schedule. Good quality, cut 4 hole in 1 /2 plywood. Came with the arbor, 2 center bits, a bonus smaller hole saw and a small tape measure. If I needed to use a hole saw every day, I buy a Lennox or Diablo. This is perfect for the few times Ill need to use it.

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.

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
