Product Details

NQ Diamond Core Bits

Diamond drilling is the most common style of exploration drilling which produces a solid core sample that is extracted for examination on the surface. This method of drilling provides an accurate assessment of the deposit as no other particles have a chance to contaminate the ore sample.

The key technology to diamond drilling is the actual diamond drill bit which is comprised of industrial diamonds set into a soft metallic matrix. The drill bit is mounted onto a drill stem, which is connected to a rotary drill. Water is injected into the drill pipe to wash out the rock cuttings produced by the bit. The diamond drill bit is complex and usually designed for a specific rock type.

Diamond drilling can be completed in various sizes depending on the size (diameter) of the core sample required for examination. The most common diameter sizes of core are NQ, HQ and PQ.

Pinnacle Drilling has the current capacity to utilise diamond drilling in the following sizes.

Size	Hole (outside) Diameter, mm	Core (inside) diameter, mm
BQ	60	36.5
NQ	75.7	47.6
HQ	96	63.5
