Review on 🏗️ Cemented Carbide Concrete: Gunpla's Multipurpose Multi Material for Superior Results by James Gregg

The price certainly reflects the quality. I used them to drill holes in porcelain stoneware and it took me 3 drill bits to drill 5 holes. They worked, but the bits broke after each drill hole. It's definitely no coincidence that they sell them in packs of 10. If you have a small job and don't want to spend a lot, they'll get the job done. If you're looking for a racquet that will last a while, you'll have to look elsewhere. Update: I tried grabbing a spray bottle and leaving water in place while firing the bat and that seems to have helped. Spicy. I used 1 drill for about half a dozen holes in the glass tile and the drill could do more.
