Will a diamond drill bit go through metal?
Not effectively—diamond bits are for non-metallic materials; they can burn out quickly on metal.
Why are diamond drill bits so cheap?
Many use a thin coating of industrial diamonds, which is inexpensive to produce compared to solid carbide.
Which is better, carbide or diamond drill bit?
Carbide for metals; diamond for hard, brittle non-metals.
What is the lifespan of a diamond drill bit?
It depends on material, cooling, and use—can range from a few holes to dozens when properly used with water cooling.
What is the difference between diamond and tungsten drill bits?
Diamond bits cut by abrasion; tungsten carbide bits cut by shearing. Each is best for specific materials.
What is the difference between a diamond drill and a hammer drill?
A diamond drill uses abrasive cutting with diamonds; a hammer drill uses percussive force to chip away at material.
What is the best drill bit for metal?
Carbide or cobalt drill bits are the best for metal—diamond bits are not suitable.
What are the disadvantages of diamond drilling?
Slower drilling speed in some materials, higher cost, and the need for constant cooling and cleaning.
What are the disadvantages of diamond drill bits?
They wear out quickly on soft materials, can be expensive, and require water cooling to prevent damage.
What are diamond drill bits used for?
Drilling through glass, ceramic, porcelain, tile, granite, marble, and other hard, brittle materials.
