Review on 💎 BGTEC Diamond Granite, Masonry, and Concrete Surfaces by Logan Broadnax

I had to drill a lot of holes in the bathroom wall tiles for shower screen, shower rod, toilet holder, towel holder. I got 1.5 to 2 holes per Drill bits. Start at an angle, and then when making a small purchase, slowly work your way up to vertical and drill straight. You'll still go, but much slower. Also, it's not a full 1/4". So if you're using wall anchors, finish the hole with a real 1/4 inch tile bit and life is good.
