NQ core has a diameter of about 47.6 mm, drilled from a hole of about 75.7 mm. NQ is the workhorse size for deeper diamond drilling. Holes are often started in PQ or HQ and reduced to NQ at depth, so NQ boxes are usually needed in the largest numbers. Below are all our boxes that take NQ core, each for 1 m core lengths.

- Galvanised steel: the toughest option for heavy handling.
