Ratings & Reviews for Kobalt 1-1/4-in Wet/Dry Diamond Core Drill Bit for Stone
Ratings may include incentivized customer reviews.
What Customers Are Saying
The diamond-tipped ceramic drill bit generally performs well for drilling holes in ceramic, porcelain, and glass materials, though it requires some technique to use effectively. Many found starting the hole at an angle and gradually straightening the bit, as well as using water to keep the bit cool, helped produce clean, chip-free holes. However, some reported issues with the bit wandering, wearing down quickly, or struggling to drill through thicker or harder materials. Overall, the bit seems to work best for lighter-duty applications and when used with care, but may not be the best choice for more demanding drilling tasks. Proper technique and patience are key to getting good results.

Diamond Core Drill for Bathroom Remodel
Would RecommendUsed it to help me put tile in my new bathroom. This tool is really helpful and seems to be of good quality. I'm working on the bathroom all on my own and my wife picked out the most difficult tiles she could find, of course. But this little thing has been holding on great.

Try to evacuate material every quarter inch….
Would RecommendWorked well. Takes a little practice starting the drill bit to accurately hit your mark since it doesn’t have a pointed tip. Since it’s more like s hole saw, it can sometimes be a pain trying to evacuate the material that gets lodged inside.

Would RecommendEasy to bit to use on tile. Cut through my porcelain tile well without cracking tile. It did take some time and steady pressure.
