Price was right, they work well
Just be sure to use something as a lubricant, we use WD40. Also, works easier if you start at an angle then slowly bring it perpendicular to the object being drilled as this will keep the bit from skipping across the surface. Also, ease up on the pressure before you fully puncture to avoid slamming the drill into your project.

Great product
Works wonderfully. As long as the bits are kept cool while being used. Can't wait to get an actual drill instead of a Dremel.

Use plenty of water.
Bought these to drill holes in 12" x 12" ceramic shower tile to mount a grab bar. Had to drill a total of six holes through 1/2" thick tile plus 1/2" concrete backer board. I knew I did not want to break or even crack the tile. These bits worked great. The secret to these working - keep water flowing on them as you cut. I used a spray bottle to keep the bits wet. Hardest part was holding the drill in one spot to get the bit started. So I used a 1/8" spear point carbide bit (made for cutting holes in glass) to start a hole in the glazed tile, followed with a 5/16" spear point carbide bit. Then used the diamond bit to enlarge the hole to the finished size. The diamond bits showed no wear at all when I was finished. No cracked tile, no broke tile - perfect.

Nice set of glass cutting bits.
I was surprised to see how well the 1/4 inch bit cut. Don't know how long they will last but for the money you can't go wrong.Tip: wet the bit and glass before starting. I used a battery powered drill on high speed. Angle the bit at about 45 degrees to nick the glass, then slowly raise the bit to the vertical position. Be sure to use light pressure and keep the bit damp.

It worked as advertised
Great for the price. Take your time, use lots of liquid to clear out chips. Use a high speed on your drill. Rock the drill around the hole a bit, and don't use too much pressure. Make sure there is something hard on the backside of the glass while drilling.

Works as intended.
Cut right through the glass bottle I was using for a craft. Needed just one size higher for what I really wanted, but I didn't read the sizes so that's my fault. Works fine though.
