Morse MHS76, Bimetal Hole Saw, 4-3/4" Diameter, 1 Piece

It did the job, but was kinda a beast to handle. I ended up using a large low speed 1/2" drill to go through wood. I went through a 2x12 & 3/4" OSB and the second it touched the wood, it just really dug in, so you have to go really slow and not apply very much pressure or it will bind. Seems like maybe the teeth are too big / too sharp? I only had a couple of holes to do, so I did not want to spend an arm and a let for a high end hole saw. It fit my standard arbor, but did not thread into that very smoothly or as well as many of my other hole saws. You get what you pay for I guess.

I used this bit to drill two 120mm holes in my PC case for fans. I used CutSpan oil to lubricate the hole saw and my cordless drill. It cut two clean holes through my steel computer case no problem. I don't know how long it would last but for the price it works good for a small project like mine.Please also note you will need a center guide bit for this hole saw to work, as it doesn't come with one.

Great Quality!!!

Worked great cutting speaker hole through fiberglass console for my boat

This hole saw is very sharp and works very well, cuts great through wood and light metal, I would definitely recommend!!! Thank you!
