Galaxy S8 Screen Protector [2 Pack], Amazingforless Tempered Glass Screen Protector 3D Full Coverage Curved Protectors for Samsung Galaxy S8 (NOT S8Plus) (Case Friendly)

BACKGROUND: I needed this to cut some holes into alcohol containers, and it did just that!On to the product!ACCURACY: Package received as advertised.QUALITY: The only identification for the size of each bit is in ink, and some of the ink rubbed off of some of them. Yet, this isn't $30 a drill-bit so I wouldn't expect any more than what was provided. What matters: It cut through the glass I needed it too with no problems. I have made multiple cuts with the same bit, and it's holding up well.SHIPPING: Great!PRICE: FANTASTIC. I bought 1 bit at Lowes for $30. I wish I would have just bought this instead!OVERALL: I am satisfied. I would purchase again.

I'd first would like to say, I love Amazon.com however I had a large flower pot that needed a couple of drainage holes so purchased the Diamond Coated Core Hole Saw to core the holes. I used the 25 mm and on the 2nd hole the shaft broke away from the saw. I finished with the next size down. I finished my task but don't expect these tools to last, one and done.

Works great, made a few water bongs out of old school liquor/tequilla bottles, takes a little while but it cuts nice holes

Worked great cutting holes in glass. I submerged the bottle and bit tip in water to keep bit lubed and dust down

Was a little hesitant to purchase at such a cheap price. They work great! Use a little water to keep them cool while you are drilling.

Worked for only once or twice~ Doesn't last at all.

I bought this item for a ceramic flower pot. The diamond coated hole saw make a perfect 360 degrees cut into my ceramic flower pot without cracking.A great tool !

They worked as expected! I am using them for craft projects and am very happy with them
