I had no problem drilling through the piece of glass I had drilled through as a test, went through rather fast and quite smoothly.

It cuts 1/8 glass 2 time and I use it to reming out the hole "you shouldn't not do that" because I bought one to small but it look like new still so I say there made well enough for the price for something you use one or two times it be a 5 star if one of the two wasn't bent

Because of what I was using it on which was a kitchen sink classic kitchen sink thick hard porcelain lead mix did not make it through but it dug almost all the way through.

I needed to make some holes in a glass jar, luckily I got the 2 pack because the first bit wore out after making just one hole. The bonded diamond grit did not stay bonded. I used both these bits with a water pool at the cut location for cooling and material removal but one of the bits just didn't hold up well.

Wobbled from first use. Was still able to cut a hole in aquarium glass, wut was nervous the wobble would shatter the glass. Also area where diamond grit was missing. They work and are Cheap, but also cheaply made.
