5.SHANK ADAPTERS

In top hammer drilling, the “drifter” is the percussion rock drill mounted at the top of the drill string. A shank adapter (also called a shank rod, drill shank, or striking bar in some regions) is the connecting component between the drifter (rock drill) and the drill string in top hammer drilling. It’s one of the four standard consumable parts, alongside drill rods, couplings, and drill bits. We offer over 300 different shank adapters for common rockdrills/drifters.

Top hammer Common drifter models include what types?

Epiroc (formerly Atlas Copco) — COP Series

The COP range spans light to heavy-duty hydraulic drifters, organized roughly by size/energy class:

COP 1838 / 1838+ / 1840 – Compact, high-frequency drifters used mainly for underground face drilling (e.g., on Boomer rigs), known for high penetration rates in medium-diameter holes.
COP 2160 / 2160EX / 2560 / 2560EX – Mid-range units for underground and surface production drilling; EX variants typically denote extended-life or reinforced configurations.
COP 3038 / 3060 / 3060CR / 3060ME / 3060EX / 3060MUX – Heavier-class drifters for larger-diameter surface and underground holes, with MUX/CR/ME suffixes indicating multiplex control, corrosion-resistant, or specific mechanical/electronic configurations.
COP 4038 / 4050 / 4050ME / 4050MEX / 4050MUX – High-energy drifters for large-hole surface production and long-hole drilling.
COP 5060CR – Top of the range, for the heaviest surface production applications.
COP SC series (SC16, SC19, SC19X, SC25-HE/HF, SC25X) – “SmartROC”-compatible drifters designed for Epiroc’s surface crawler rigs.
COP RR series (RR11, RR14) – Used in raise boring/reverse circulation type applications.
RD series (RD8, RD14S/U, RD18S/U, RD22S/U) – Featured on newer Epiroc surface top hammer rigs.
DHR series – Compact drifters for smaller rigs and specialty drilling.

Sandvik — RD and legacy HL Series

RD series (RD520, RD525, RD720, RD314, RDX5) – Current-generation hydraulic drifters used on Sandvik’s Ranger, Pantera, and DX/DP rigs.
HL series (legacy Tamrock design, still supported: HL500, HL510, HL550, HL600, HL650, HL700, HL710, HL800T, HL1000, HL1010, HL1500, HL1560T) – Older but widely deployed drifters, numbered roughly by increasing impact energy class; still common in existing fleets and parts markets.
HEX1, HLX5, HLX5T – Cross-reference/updated variants of the HL line.

Furukawa Rock Drill — HD Series

HD609, HD612, HD709, HD712, HD715, HD1213 – Hydraulic drifters used on Furukawa’s own rigs (e.g., HCR series) and supplied as OEM units on various other drill rig brands, particularly across Asia.

Montabert — HC Series

HC50, HC109, HC120, HC158 – French-engineered hydraulic drifters historically fitted to European drill rigs (Montabert-built and OEM), numbered by increasing size/impact class.

Tamrock (legacy, now part of Sandvik)

Tamrock’s own HL-series drifters predate Sandvik’s rebrand and are functionally the ancestors of Sandvik’s current HL line above — many of these units remain in service and are supported by aftermarket parts suppliers even though “Tamrock” is no longer an active brand.

A note on interpreting model codes: across most of these families, the numeric portion generally correlates with piston/impact energy or drifter size class (higher number = larger/heavier-duty drifter), while suffixes (EX, ME, CR, MUX, S/U, HE/HF) typically indicate a specific configuration — extended durability, mechanical vs. electronic control, corrosion resistance, or surface vs. underground tuning — rather than a fundamentally different drifter.
