The laser drilling process involves the use of an infrared laser (of surgical grade at a wavelength about 1064 nm) to bore very fine holes (less than 0.2 millimeters or 0.005 inches in diameter) into a diamond to create a route of access to a black carbon crystal inclusion.
3. Mark the area where you plan to drill. For small diameter holes, you can use a small dot. For larger diameter holes, use a template or draw a precise circle that corresponds exactly with the diameter of the hole youâre drilling.. Make certain you really, really, really need to drill a hole where youâre thinking about drilling one. Consider other alternatives before you start putting holes in your granite, especially when youâre working with something as expensive as a granite countertop.
