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

When mounting the mandrel to the hole saw. The pins were hard to get in the hole saw clock to match the pins. I had to put tape on the mounting surface to get a tight fit. Secondly the set screw for the drill bit would not screw in. Had to chase the threads. There was tiny pieces of metal in the thread. Hope there is a resolution?

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.

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.

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.

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.

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!

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

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...

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.

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.
