Overview

ISO 10097-1:1999 specifies the nomenclature and principal dimensions for wireline diamond core drilling equipment - System A - in metric units. It defines the dimensional and material requirements needed to ensure interchangeability of components used to drill holes 48 mm to 96 mm in diameter and recover cores 27 mm to 63 mm in diameter. The standard covers core bits, reaming shells, core lifters and cases, outer and inner core tubes, and smooth drill rods.

Key topics and technical requirements

• Scope and designation
  • Items are identified by the prefix WL plus hole-dimension letters (A, B, N, H). Example: WLB core bit.
• Component list
  • Core bit, reaming shell, core lifter, core lifter case, outer tube, inner tube, drill rod (smooth pipe).
• Materials
  • Minimum mechanical properties specified for drill rods and core tubes: tensile strength 690 MPa, yield 550 MPa, elongation 12%. Other items are not specified.
• Dimensions and tolerances
  • All dimensions in millimetres; detailed tables for each component (core bit, reaming shell, lifter, tubes, rod) set max/min values and thread pitches.
  • Rod lengths commonly 3 m, 1.5 m, 0.75 m (DCDMA/CDDA conformity may use 3.048 m, 1.524 m, 0.762 m).
• Eccentricity and straightness
  • Eccentricity (distance between outer and inner centres) shall not exceed 10% of nominal wall thickness Q; eccentricity is calculated from measured Qmax and Qmin values.
  • Straightness limits when rolled against a straightedge: drill rods 1 in 2 000, core tubes 1 in 1 500.
• Threads and joint details
  • Annex A (informative) provides principal drill-rod thread dimensions (taper, pitch, diameters, spire depths). Thread pitches and profiles are listed per WL size.

Applications and users

ISO 10097-1 is essential for:

• Manufacturers and OEMs of wireline core drilling equipment to ensure parts are interchangeable and compatible.
• Drilling contractors and mining/geotechnical operators who specify or procure System A wireline assemblies.
• Design engineers, QA inspectors and maintenance teams who verify dimensions, threads, material properties and straightness.
• Procurement and spare-parts management to match WL designations and accept interchangeable components.

Practical benefits include reduced downtime, simplified spare-part inventories and confidence in compatibility across suppliers.

Related standards

• ISO 10097-2 - System A, Inch units (companion part)
• ISO 3551-1:1992 - Rotary core diamond drilling equipment - System A - Metric units (normative reference recommended for combined use)

Keywords: ISO 10097-1, wireline diamond core drilling equipment, System A, metric units, core bit, reaming shell, core lifter, drill rod, interchangeability, dimensions and tolerances.

The eccentricity is calculated according to the formula:
QQ-max min
·100

5.4 Straightness
When measured over the whole length of the tube by rolling against a straightedge, the maximum deviation shall not
be greater than:
 for drill rods 1 in 2 000;
 for core tubes 1 in 1 500.
5.5 Technical conditions
Tubes should be made seamless. Tube rolling technique and machining operations are optional.
Tube straightness is checked by rolling the tube on a horizontal or slightly inclined flat surface. When rolling, no
