Equipment-class discovery • Systems vary with configuration
What to identify on foundation and production drills
Foundation and production-hole drilling share a category but different tooling and assembly needs. Identify rotary head, mast, kelly or drill-string/hammers explicitly.
Record drill type and installed head/tooling designation. Ask for connection, inspection and applicable operating-scope evidence rather than relying on machine size.
No torque, load or connection equivalence is inferred. Rotating and load-bearing tooling needs qualified technical review.
Assembly identification briefs
Use these component-specific questions to prepare a precise identification record or quote request. The source references explain component families; exact values and machine applications require the correct installed assembly documentation.
Kelly bars, telescopic joints and locking collars
Identify the foundation rig's installed Kelly bar and rotary-head configuration before comparing telescopic joints or locking collars. Preserve bar identifiers and repair history with the inquiry. A used bar requires traceable inspection evidence; a matching outer dimension cannot establish locking geometry, torque approval or application to the rig.
Identification and inspection record
bar type
rotary head
torque rating
Source scope: Public Kelly drilling-system family reference; Kelly-bar internals, rotary-drive internals and torque approvals not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Record the actual auger or drilling-tool identity and fitted pilot or tooth family before comparing cutters. Describe ground conditions as application context and retain tool markings. Used tooling should disclose repairs and wear, while nominal auger diameter alone cannot establish the cutting-tool interface or material suitability.
Identification and inspection record
auger diameter
cutting tool family
Source scope: Public auger, casing and drilling-tool families; no cutting-tooth, clamp or oscillator component application assigned. The reference supports component-family context; it does not establish an individual machine application.
Identify the rig's installed rotary head and its drive or coupling references separately from the Kelly bar. Keep unit labels and any documented conversions in the request. A rebuilt head should have traceable inspection and testing evidence, leaving adapter geometry, torque approval and machine application to the relevant technical records.

Source scope: Public Kelly drilling-system family reference; Kelly-bar internals, rotary-drive internals and torque approvals not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Identify the casing and oscillator or clamp arrangement as an installed system before requesting wear pads or clamping parts. Preserve available identifiers and actual interface documentation. A used package should disclose condition and modifications, while casing diameter alone cannot establish the correct oscillator variant or approved components.

Source scope: Public auger, casing and drilling-tool families; no cutting-tooth, clamp or oscillator component application assigned. The reference supports component-family context; it does not establish an individual machine application.
Keep hammer, bit and drill-string identities separate when researching down-hole tooling. Record shank and connection references and the documented operating-medium class. A used tool should disclose wear and repairs, while apparent bit size cannot establish hammer fit, permitted operating conditions or compatibility with the intended drill string.

hammer shank

bit design
Source scope: Hammer, bit and drill-string product-family reference; no shank, operating rating or rig-specific compatibility assigned. The reference supports component-family context; it does not establish an individual machine application.
Identify mast-feed cylinders, slides and tension assemblies from the rig's actual mast arrangement. Keep labels, mounting positions and previous repair information with the inquiry. A used assembly needs provenance and documented inspection, while feed travel, hydraulic requirements and structural acceptance remain unresolved until the correct rig documentation is supplied.
Identification and inspection record
mast travel
hydraulic configuration
Source scope: Machine-OEM portal route; mast-feed and structural part drawings not acquired. This reference provides a documentation access route; topic-specific technical details have not been established.
Start with the manufacturer, model suffix and installed equipment. The following specialist subjects help describe a sourcing request; they do not identify a specific orderable part.
Kelly bars
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
rotary heads
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
drill strings
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
hammers
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
tooling
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.
For a used or rebuilt component, ask for its donor-unit provenance, inspection record, repair scope and any remaining identification marks. A donor model is context, not proof of fitment to another machine.
Foundation and production drilling: distinct tooling branches
BAUER explains Kelly drilling through a telescopic Kelly bar and describes different casing-installation methods. This supports a foundation-drilling branch within the category. Production-drill hammers and drill strings remain a separate architecture requiring their own manufacturer evidence.
Architecture and assembly boundaries
A foundation rig transfers torque and crowd through rotary equipment and the fitted bar or tool. Kelly sections, locking interfaces and drive keys must be distinguished from the rotary-head gearbox and mast feed. Casings and oscillators introduce another load path. In a production-drilling branch, hammer, bit and drill-string interfaces require different identification. The category deliberately groups related equipment contexts without implying that a Kelly bar, auger and downhole hammer belong to one universal machine assembly.
Variants that change the research path
Friction and mechanically locking bar arrangements, crowd systems, casing methods and rotary-head builds create distinct selection paths. Nominal bore diameter cannot identify an auger-to-head connection or hammer shank. Mast and slide arrangements require the actual feed configuration. Air or fluid service also changes tooling and seal questions in production drilling. Each quoted torque or force must retain its rating conditions; a headline machine maximum is not an approved load for every installed tool or adapter.
Condition evidence and selection record
Record bar markings, contact-surface wear, damaged keys, tool connections and visible mast-guide condition without approving repair or continued use. Used tooling needs provenance and qualified inspection; photographs alone cannot establish structural integrity. Rebuilt rotary heads need exact build, ratio and test records. Leave torque, crowd force, shank dimensions and material limits blank where exact sources are missing. The six mapped workpacks remain separate investigations, particularly the production-hammer branch that the foundation-method source does not independently substantiate.
Specification evidence record
Published values retain their exact reference scope. Empty fields mean the value has not been established; they never mean zero. General model associations do not establish installed or serial-specific fitment.
