FAQ's: Diamond Drills

Not effectively—diamond bits are for non-metallic materials; they can burn out quickly on metal.

Many use a thin coating of industrial diamonds, which is inexpensive to produce compared to solid carbide.

Carbide for metals; diamond for hard, brittle non-metals.

It depends on material, cooling, and use—can range from a few holes to dozens when properly used with water cooling.

Diamond bits cut by abrasion; tungsten carbide bits cut by shearing. Each is best for specific materials.

A diamond drill uses abrasive cutting with diamonds; a hammer drill uses percussive force to chip away at material.

Carbide or cobalt drill bits are the best for metal—diamond bits are not suitable.

Slower drilling speed in some materials, higher cost, and the need for constant cooling and cleaning.

They wear out quickly on soft materials, can be expensive, and require water cooling to prevent damage.

Drilling through glass, ceramic, porcelain, tile, granite, marble, and other hard, brittle materials.
