💡 How to stop a diamond drill bit from glazing over when cutting thick ceramic tile Keeping the cutting face wet is essential since friction quickly cooks the abrasive matrix. Feeding the spindle slow lets the side slots sweep chips away without jamming the throat. Angling the nose first helps score a pilot groove before applying straight downward force. This routine preserves grit sharpness and prevents sudden motor stalling during rough passes.
