Good metal
It’s a hole saw! All I can say is it is very sharp. It It cut all the hole through my composite decking and is still sharp.

I am rating this product only 3 stars because on the first use of it the center ring bearing fell off, but it is made of decent plastic material. I will keep it as work a back up. Thanks.

I bought this to cut metal siding, first attempt broke the pilot bit. Installed another bit and never made it thru 25 gauge siding.

Great saw, as I needed to cut recessed lighting in my ceiling tile. One thing to watch is that there is no locking mechanism, therefore if not cutting and you stop your drill, the saw continues to spin, then cone off the collar. Other than that, it works great.

I’m being honest when I say I knew it was cheap. But when it bends on first use and doesn’t do what it’s intended to do I’m not gonna keep it on my shelf for me to look at it and never throw it away cause that’s whom I am. Old tools new tools doesn’t matter. But this just can’t stay for me.
