Review on Sunjoyco Diamond Cutting Porcelain 6Mm 50Mm by Dennis Reed

At first they were loose in the large envelope so that they noticeably rubbed against each other. Worst of all, the drill bits wobble in the drill bit because the shanks aren't flush with them. Yes, I tried several exercises. They work but I suggest using a guide as the freehand angle start technique creates a pretty ugly edge and will likely chip some surfaces. This is a classic case of getting what you pay for.
