Abstract
Overview
ISO 8866:1991 - "Rotary core diamond drilling equipment - System C" defines the dimensional, material and tolerance requirements for a complete family of rotary core diamond drilling components designated as System C. System C is a distinct equipment family (not interchangeable with ISO systems A or B) characterized by a series of nesting hole sizes with small clearances between hole wall and equipment, allowing use of thin‑walled casing tubes. The standard covers equipment for drilling holes with outer bit diameters from 35 mm to 112 mm (core diameters ~21 mm to 92 mm).
