Heat is what kills a diamond bit. Dry-drill dense porcelain or stone without cooling and the crown glazes over, stops cutting, and burns out — usually right in the middle of an expensive tile. Montolit M-PERFORMER Cooling Gel is the simple fix: dip the bit before you drill, and the gel coats the diamonds and bond surface, then melts in as you cut to cool and lubricate exactly where it counts.
It's made for dry-drilling situations where keeping the bit cool is the difference between a clean hole and a ruined bit. Keep it next to your FAJ diamond drill bits and FSB core bits — a dip before each hole is the cheapest insurance on the truck.
Pro tip: Re-dip every few holes, not just the first one — the gel gets used up as it does its job. On deep or slow cuts, pull out and re-coat before the bit starts to squeal or smoke.
