Full title and description
ISO 10207:1991 — Rock drilling equipment — Rope threaded drill steel equipment for percussive drilling, nominal sizes 22 mm to 38 mm. Specifies the basic dimensions and configurations for rope‑threaded drill‑steel components used in percussive rock drilling (shank rods, extension rods, coupling sleeves and drill bits).
Abstract
Defines the basic dimensions of rope‑threaded drill steel equipment for percussive drilling covering eight nominal sizes in the 22 mm to 38 mm range. The standard covers the main components of such equipment (hexagonal shank rods, extension rods, coupling sleeves and drill bits) to ensure interchangeability and correct fit.

Scope
Specifies dimensional requirements for rope‑threaded drill steel intended for percussive rock drilling in eight nominal sizes between 22 mm and 38 mm. The scope includes the principal components (hexagonal shank rods, extension rods, coupling sleeves and drill bits) and their basic interface dimensions to permit interchangeability between manufacturers.
Key topics and requirements
- Dimensional definitions and tolerances for rope‑threaded drill steel components.
- Nominal size range covered: 22 mm to 38 mm (eight nominal sizes).
- Specification of component types: hexagonal shank rods, extension rods, coupling sleeves and drill bits.
- Requirements to ensure mechanical compatibility and interchangeability for percussive drilling equipment.
- Includes a published corrigendum to correct the original edition where applicable.
Typical use and users
Used by manufacturers of drill steel and percussive drilling equipment, procurement teams in mining, quarrying and geotechnical contractors, equipment designers, testing and inspection bodies, and national standards organizations referencing dimensional interchangeability requirements for rope‑threaded drill steels.
Related standards
ISO 10207:1991 replaces earlier withdrawn documents in the same field (for example ISO 1719:1974 and ISO 1720:1974 were withdrawn and replaced by ISO 10207 and related standards). It sits within the ISO/TC 82 suite of rock drilling equipment standards and may be used alongside other ISO documents addressing drill rods,bits and connections.
