Review: Effective stucco cutter - I wanted to cut a hole for 2" OD conduit through an interior wall and exterior stucco. A normal circular bi-metal saw is not going to survive that, or even succeed at it. Having purchased this same brand's hole saw in another size for another application, I was already prepared for it to be a well-forged part. I was not disappointed -- it's solid, well packaged, and fit for purpose. The only minor issue is that if you use the supplied drill bit, you need to loosen the attachment screw before you can really insert it properly, and then tighten. If you insert the bit and just tighten it sort of feels like you've secured it but you didn't -- it won't go in all the way if you don't loosen first. That minor issue aside, I went to work drilling through solid stucco and was quite pleased with the performance. Any drilling through stucco is going to be a little bit of a challenge but this worked quite well; just apply steady pressure and take a break now and then so the saw doesn't overheat. Disclaimer: I drilled a pilot center hole first with a different cement bit, which made positioning the hole saw easy; I can't offer feedback on the included bit's performance against stucco / cement, but I probably wouldn't recommend it -- looks like a wood bit to me. But the hole saw did its job beautifully, and went through the stucco just fine. Afterwards I looked closely at the saw blades and they seem unbothered by the experience; I am not planning to drill another hole right away but have no doubt the bit is suitable to be used again. Note: The attached is midway (before drilling all the way through. A nice, clean cut.
Review: The best - Have used many different styles of large hole saws in the past and this by far is the best! it drilled a hole in a car seat bracket as fast as I could drill through pine
