Drilling, milling, paving & cutting
Drilling, milling and paving share replaceable work elements, but their component boundaries are substantially different. A drill string, milling drum and paving screed cannot be researched using a generic cutter identity. Begin with the installed work assembly and identify its holder, connection or compaction architecture before selecting an individual consumable or wear component.
The work assembly defines the part family
Wirtgen distinguishes welded and quick-change toolholder architectures [TOOL-HOLDER] [TOOL-HT08]. Epiroc's tophammer overview describes the drill string through shank adapters, rods and bits [TOOL-DRILL]. VÖGELE separately identifies vibrator, tamper and pressure-bar compaction functions [TOOL-SCREED]. These are different engineering boundaries, not interchangeable tooling categories. HeavyEQ interpretation: identify the actual drum/rotor, drill-string system or screed model before using the carrier's name as a sourcing key.
Capture interfaces and generations explicitly
For milling, preserve pick/holder generation, drum identity, relevant position and retention arrangement. For drilling, record shank/thread/connection design and the issuer's exact tool designation; a nominal drilling diameter does not define the complete string. For paving, separate basic screed, extensions, heating and individual wear elements. Document any changed work assembly or retrofit rather than assuming that a historical machine model retains its original tooling. Keep proprietary series names intact until an actual replacement source establishes a relationship.
Read wear as a documented observation
Request dated views of holder seats, retainers, tool bodies, threads, worn plates and mounting interfaces, with orientation and exact identity. A seller should distinguish a new consumable from an overhauled work assembly and describe which supporting parts were inspected or replaced. For a drill string or milling assembly, ask for traceable professional inspection where condition is uncertain. For a screed, record the affected component/position instead of interpreting an uneven mat or wear pattern as proof of one specific cause.
Keep operating settings outside the identification record
Cutting radius, tool spacing, thread geometry, material, heating and compaction settings need exact, configuration-specific evidence. None is assigned to a HeavyEQ machine here. Surface appearance cannot establish carbide grade, hardening or remaining structural capacity. Tool changes, rod handling, holder welding, drum work and screed adjustment require applicable manufacturer procedures and qualified service. This hub provides no welding pattern, drill operating parameter, tamper setting or heater instruction; it prepares a precise record for documented selection and later technical review.
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.
| Property | Value / status | Scope and interpretation |
|---|---|---|
| Installed work-assembly identity | Not yet documented | Identify the actual fitted work system independently of carrier. |
| Tool/holder/connection generation | Not yet documented | Preserve welded/quick-change, thread/shank and retention variants. |
| Position and mounting geometry | Not yet documented | Keep handed/section/extension location and interface evidence. |
| Cutting/tooling dimensions | Not yet documented | No dimensions inferred from photographs or nearby models. |
| Material/wear component specification | Not yet documented | Separate consumable material from assembly fit. |
| Screed compaction/heating arrangement | Not yet documented | Identify vibrator/tamper/pressure-bar and heater variants without settings. |
| Inspection/overhaul scope | Not yet documented | Attribute the actual work and exact tested/inspected assembly. |
