diamond drill bit

We needed to drill a hole for an instant hot water faucet and this blade cut through the counter very fast and didn't require much effort. The bit left a perfect finish and is a great value for the price.

Great bit for cutting into different types of tile. I like to use another bit which has a center bit to start the hole then switch to this one.

I bought a Home Depot hole saw similar diameter to drill into clay pots as planters, could not drill though ceramic…took for ever and heavy pressure, still not get through. Got this hole saw, love it! Works great, having 2nd one back up is great! Today i drilled 5x ceramic plates/bowls to use for plants/flowers. Bit tip is still strong, put pressure and angle at different point for better grip. Drilled with a bit of water to control dust, and cleaned bit, looks as new. Love it, highly recommend. Diameter is good for most clay ceramic planter types.. on my favorite, to purchase again when my bits wears.

I used this bit to clean up some 7” deep holes in a cement foundation. It quickly did the trick; however I wish the cup was deeper.

Had slightly undersized holes on my granite top vanity for a new 4 inch Moen installation, worked well drilling serviceable holes with some water for cooling.

Needed to drill a hole in my granite counter top to put the reverse osmosis spout in. I was timid using this drill bit as the price normally reflects quality. I read a lot of reviews and most of the bad ones are about longevity or arrived damaged. I ordered a 2 pack but only needed 1, after drilling the hole the diamond grit is still there and the hole was a clean circle. If you’re looking to use this item for a single Job, I highly recommend

Wanted to drill 1" hole through ceramic tile. This bit went through it easily with a nice clean cut. I didn't run it very long at a time just to make sure it didn't overheat. I had a small cup of water to dip it in to cool it between. Instructions were good (recommended a corded drill rather than a battery operated, and don't lean into it too hard). Be sure to read how to start the hole by tilting bit first to get an arc started. There's no central drill like mist hole saws for wood. Good value.

I recently installed a garbage disposal and needed to cut a hole in my sink for mounting the switch. I wish I had done more research ahead of time to know what type of bit I needed because I spent way too long (and used way too many profanities) before I found this amazing tool.Lesson learned - use this. It took me less than 10 minutes to cut through the sink.
