7/8" (22mm) 2Pcs Diamond Hole Saw with 2Pcs Removable Pilot Drill Bit Smooth Cutting for Porcelain Tiles,Glass,Ceramic,Marble,Fiberglass,etc.

These hole saws worked great at a very good price.

Used to cut hole in porcelain tile. The spade pilot drill worked great to start the hole after which the diamond centering drill and the hole saw cut the tile with no problem. Great value.

I purchased a quartz sink and needed to cut a hole for the soap dispenser. This thing cut amazing. I was so scared of it walking but I had none of that with this saw. It cut right through the quartz like butter.

This worked okay, but it cuts slower than the Bauer hole cutter, and it is a bit more expensive than my Bauer. I ended up taking out the center bit halfway through my first cut.It cuts very clean, but you have to be patient. I used this on porcelain tile and it was very smooth. I used a portable drill press for a nice straight cut.Harbor Freight discontinued the hole cutter, so guess this will do. I only need it for one more cut, so it will be fine. The price point is good compared to other brands, but I'm thinking this is more for the DIY'er than professional.

As the title says, it works very well when drilling through fiberglass.

Did a great job drilling 20 holes through 2 inch marble

This is an update to my original review below. While the item was obviously used not new, it functioned well in my project, easily cutting 6 holes in 1-inch quartz countertop. The vendor politely responded to my concern but no follow-up is needed since the item still worked well, especially considering the price point on the item. I would therefore recommend this item.Original review: I received this item this afternoon, 8/10/24. This hole saw was packaged in a screw cap bottle. The cap seal was the original label which had been torn at the overlap with the cap and reapplied nearby. A new, different barcode label was applied over the original label. There is a burnish mark around the circumference of the hole saw at approximately 1 inch depth, apparently from previous use. Also the diamond grit edge does not feel as rough as I would expect for a new item. When listed as a new item, I expect new. Disappointed would be putting it politely.

Fast delivery and drilled perfect hole on stone sink

This guy saved me on that steel plated door. My bi-metal hole saw tore and caught where the diamond hole saw just laughed and went right through. Might need to do the wood thing to hold it in place as you drill though.

Drilled multiple holes and the bit worked well.

Used it to drill a few holes in terra cotta . Cut nice clean holes with no wandering. Go slow and keep surface wet. Not sure how many uses you will get but I was happy with.purchase.
