Used the 35mm bit for the shower valve pipe installation. It made a perfectly clean cut with absolutely zero chipping on my expensive ceramic tiles. Highly recommend for any home DIYer!

Remodeling my master bath and these bits cut through hard porcelain tiles easily. Love the dry drilling design so I don't need a messy water cooling setup. The diamond coating is very thick.

Having the complete 12 piece set in a neat storage box is so convenient. No more digging around the bottom of my tool bag for the right size.
