If you use this drill bit as its supposed to be used it works quite well. I used a water bath (constant water is essential) and drilled several holes in agate with no problems. Don't force the bit; take your time

Terrible product. Burned up trying to drill one hole in porcelain tile. Used a Blue Granite carbide bit and got the job done. Do not buy. Would give it 0 stars if I could.
