· Drill speed: A normal drill speed for NQ drilling is around 5-10 meters per hour without stop. The drill speed depends on numerous factors, for example rock type, homogeneous rock, wear of the drill bit, flow of water, depth of drilling, terrain and more. An example of drilling in one 24-hour period: 7,5 meters x 24 hours = 187,5 meter/day.

Drill Size Chart. The drill size chart provides a list of standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. The decimal equivalents of the diameters are shown in both English and Metric units. Fractional sizes are measured in inches, while metric sizes are measured in millimeters.
Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions.
