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

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...

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.

Works well, very sharp.

Worked great for 5” Halo Old Work Can lights.

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.

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.

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.

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

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.
