Bits, drill strings, COPROD / DTH tools and drilling wear areas

Official Epiroc drill and tooling images are preferred. Material links support engineering selection of ANRANST replacements; they do not represent a single OEM grade for all Epiroc models. Confirm against drawings, original-part inspection, rock, hole diameter and failure mode.

Rotary Roller-Cone Bits

Rotary Tricone Drill Bits

Installed at the bottom of the rotary drill string, the bit directly breaks rock. Check hole diameter, IADC cutting structure, steel teeth or carbide inserts, open or sealed bearings, circulation method, thread and rock strength. The drill model alone is insufficient for bit selection.

Material Selection:Evaluate cutting elements and inserts within tungsten carbide systems. Confirm cones, legs and the threaded body against high-strength, tough alloy steel, surface strengthening, bearing and sealing requirements.

Bit Shirttail, Bearing and Nozzle Wear Areas

Shirttail, Bearing & Nozzle Wear Zones

Shirttails, cone noses, nozzles and bearing areas are exposed to abrasive cuttings, rotational wear, impact and wet conditions. Used-bit failure analysis should distinguish cutting element wear, shirttail wear, bearing failure, nozzle blockage and thread damage.

Material Selection:Localized wear protection, carbide protection and the body alloy steel must be designed together. Increasing surface hardness alone may increase cracking risk in the bit legs, threads or bearing areas.

Shock Absorbers, Saver Subs, Drill Pipes and Stabilizers

Shock Absorber, Saver Sub, Drill Pipe & Stabilizer

Pit Viper and DM rotary drill strings commonly include shock absorbers, saver subs, drill pipes, bit subs or roller stabilizers, with deck bushings centring the string. Images locate mast and string areas; confirm individual parts against the full model, mast, pipe outside diameter, thread and assembly drawing.

Material Selection:Drill pipes and connections must meet stiffness, bending toughness, fatigue strength, thread strength and outer-wall wear requirements together. Confirm dedicated drilling tool alloy steels and heat treatment accordingly.

COPROD Tools and Couplings

COPROD Drill String & Couplings

SmartROC CL uses COPROD. Rods, tubes, couplings, bits and the percussion unit form a complete system, with wear concentrated at threads, splines, guides and cuttings return areas. Do not describe these as conventional rotary drill strings or DTH tools.

Material Selection:Confirm tool bodies and connectors against high-strength, tough, fatigue-resistant alloy steel requirements. Surface strengthening, core toughness, straightness and thread geometry jointly affect service life.

DTH Hammers, Bits and Splined Connections

DTH Hammer, Bit & Spline Components

SmartROC D60 and selected DM and Pit Viper models configured for DTH use down-the-hole hammers and matching bits. Confirm hammer dimensions, bit diameter, splines, retaining rings, check valves and air supply parameters. The image locates the D60 DTH tooling system.

Material Selection:Confirm bit inserts within carbide systems, and hammer bodies, splines, pistons and connections against fatigue-resistant alloy steel, surface strengthening and dimensional fit requirements.

Deck Bushings, Guide Blocks, Dust Hoods and Track قطع الغيار المستهلكة

Deck Bushings, Guides, Dust Hood & Track قطع الغيار المستهلكة

Deck bushings and guide blocks control drill string position; dust hoods, skirts and extraction passages face abrasive rock dust; track shoes, rollers and guides face ground wear. These three groups occupy different positions, so submit separate close-up photos and dimensions.

Material Selection:Assess deck bushings within bearing or wear-resistant alloy systems; dust skirts and seals within wear-resistant elastomers; track and guide wear parts within high-strength, tough alloy steel or quenched and tempered wear plate systems.

Core spares for rotary drives, feeds, compressed air, hydraulics, undercarriages and masts

Group parts by movement and assembly. Rotary heads, gearboxes, feed systems, compressors, hydraulic parts, final drives, pins and bushings must be matched to the full model, assembly number, installation position and drawing. Appearance alone is insufficient.

Rotary Heads, Main Shafts, Gearboxes and Chucks

Rotary Head, Spindle, علبة التروس & Chuck

The rotary head transfers drive torque and axial load to the drill string. It includes electric or hydraulic drives, gearbox, main shaft, bearings, seals, chuck and connecting flanges. Check the machine model, rotary head model, assembly number, speed, torque and interface dimensions as a system.

Material Selection:Check gears, main shafts and splines for transmission alloy steel, tooth surface strengthening and fatigue strength. Confirm housings, bearings and seals separately against original drawing materials, tolerances and lubrication requirements.

Feed, Hoist, Wire Rope/Chain and Sheave Systems

Feed/Pulldown Drive, Cable/Chain & Sheaves

Feed and hoist systems move the rotary head or tools along the mast, using cylinders, chains or wire ropes depending on the design. Check mast version, feed length, sheave reeving ratio, tensioning structure, chain links or rope diameter, end connections and installation position.

Material Selection:Check sprockets, sheaves, pins and connectors for high-strength, tough alloy steel and contact fatigue resistance. Confirm wire ropes, chains and end connections against loads, safety factors and inspection requirements.

Compressors, Air Ends, Coolers and Air Lines

Compressor, Airend, Cooler & Air Circuit

Compressed air powers DTH percussion, cools bit bearings and removes cuttings. Confirm compressor air ends, couplings, coolers, filters, valve blocks, hoses and fittings against capacity, pressure, drive type and machine configuration.

Material Selection:Confirm drive shafts and couplings against alloy steel requirements, cooling and air lines against pressure class and medium, and seals and hoses against temperature, oil/air compatibility and pressure-pulse fatigue.

Hydraulic Pumps, Valve Blocks, Cylinders, Hoses and الموانع

Hydraulic Pumps, Valves, Cylinders, Hoses & الموانع

Hydraulics power levelling, mast movement, feeding, rotation, travel and auxiliary functions. Provide pump and valve nameplates, cylinder assembly numbers, rod diameter/bore/stroke, ports, pressure, seal groove details and hose fitting standards.

Material Selection:Check piston rods, cylinder barrels and valve spools against surface, dimensional and fluid requirements. Select seals by oil, temperature, pressure, speed and groove geometry, not outside diameter alone.

Tracks, Sprockets, Track Rollers and Final Drives

Tracks, Sprockets, Rollers & Final Drives

The crawler undercarriage includes track shoes, links, sprockets, idlers, rollers, tensioners and final drives. Confirm the machine model, undercarriage version, left/right position, pitch, mounting dimensions and final drive assembly number.

Material Selection:Ground-contact track parts must balance impact resistance, abrasion resistance and core toughness. Confirm wheel shafts, gears and splines against transmission alloy steel and surface strengthening requirements.

Masts, Pivot Pins, Bushings and Levelling Jacks

Mast, Pivot Pins, Bushings & Levelling Jacks

Mast and levelling structures determine drilling position and stability. Pins, bushings, hinge lugs, cylinder trunnions and jacks withstand alternating bending, impact and sliding wear. Repairs require checks of geometric datums, concentricity, welding and non-destructive testing requirements.

Material Selection:Check pins for high-strength, tough alloy steel and surface strengthening. Select bearing steel, copper alloy or composite bushings according to the original design. Ordinary wear-resistant steel cannot directly replace load-bearing structural components.

Drawing and spare part numbers

Identify the catalogue number, then confirm its model, tooling and position

The available local Epiroc records contain no spare part numbers ready for publication with verified links to specific drill models. This page therefore lists no placeholder numbers. Submit an Epiroc OEM number, third-party number, assembly number, catalogue page or used-part marking for identification.

Submit an Epiroc OEM or assembly number Check the model, serial number, mast, rotary head and installation position Submit a third-party spare part number Establish the links between supplier, equipment, part, dimensions and material Submit catalogue pages, drawings or a used part Without a reliable number, assess catalogue lookup or reverse measurement

Numbering rules:Only numbers traceable to OEM catalogues, drawings, nameplates or reliable third-party cross-references are published. Bit catalogue numbers also require confirmation of diameter, thread, IADC, bearing and circulation method; the drill model alone is insufficient.

Are DM, Pit Viper and SmartROC tools interchangeable if the hole diameter is the same?

No. Also check rotary, DTH or COPROD method, pipe outside diameter and thread, rotary head, mast, feed, compressed air, bit structure and specific assembly drawings.

What is the minimum information for a surface drill spare parts enquiry?

Provide the full model, serial number, drilling method, hole diameter, mast and rod configuration, assembly or OEM/third-party number, installation position, used-part photos, critical dimensions and material or hardness information.

Can drill parts be identified without an Epiroc OEM number?

Start with the nameplate, catalogue pages, installation position, used-part markings, photos and critical dimensions. These support assessment of catalogue lookup or reverse measurement. Part numbers and interchangeability are not invented on public pages without reliable evidence.
