What Customers Are Saying
The diamond-tipped hole saw bit provides mixed performance. Some users report excellent cutting ability and durability, especially when drilling through softer materials like tile and glass. However, many others experienced the bit wearing out quickly, particularly when used on harder surfaces like granite and porcelain. Proper use with water cooling and lubrication can help extend the bit's lifespan, but overall quality and consistency seem inconsistent.

Would Not RecommendSynthetic diamond wears off the front of the bit in a matter of seconds, making it completely useless. What a waste of money!!
Never purchase
Got one hole out of this terrible bit

Have a back up bit.
Would Not RecommendI wasn't even able to drill one hole with it cost me hours of my time to have to go get another one very disappointed.
Quick
Would RecommendCut through the granite quick and precise. Price was reasonable quality was high.
Great for porcelain
Would RecommendThis hole saw was just what I needed for some tile. Made a good circle. Don’t put it flat to start, use a bit of an angle on it where you want to start then move it around a bit.

Doesn't last
Would Not RecommendBought this for a porcelain tile job I was doing. The 3/4" bit did 1 hole, when I attempted the second hole, it was shot. For almost $40 I was expecting more. When I went back to the website I found the product has no warranty. Don't waste your money.
Works great
Would RecommendFirst time using. Worked great, used on a granite counter top to add a ro water system.
Best drill bits around
Would RecommendDrlled like going through butter
Use water when drilling thru quartz
Would RecommendIt did an ok job drilling through the quartz compost sink. Definitely had to use water during the drilling, wouldn't have worked otherwise.
Garbage
Would Not RecommendDrilled ~7 holes and then wore out, completely. Diamond grit doesn't last whatsoever. If this was priced at $3 sure maybe it'd be worth it. At $18 this bit is a total piece of trash. What a waste of money. Like many, I'll be going to Hammer Barn and buying the Milwaukee version. Thanks Lowes!
It works as advertised
Would RecommendI used this bit in combination with the multi construction masonary bit, to drill mounting holes in tile shower. They both worked okay.
Limited usefulness not worth the money
Would Not RecommendIt worked for drilling holes in three pots, and then stopped working, wore out, not worth the money
Does a great job
Would RecommendWorked great on ceramic tiles

Garbage
Would Not RecommendAnyone who says this bit is good is lying. Worst bit/brand to ever hit the market. Lowe’s constantly drops name brands to stock their shelves with this garbage. 2 separate bits could not drill one hole. The diamond grit looks like it’s glued on by the Elmer’s glue my kid has in his school box. Went to competitor store bought a Milwaukee bit, drilled 6 holes one bit same tile. Do not buy this
