Two Different Engineering Philosophies
The honest answer to 'which brand is better' is that it depends on what you're breaking, how often your service team sees the machine, and where your dealer network is. Epiroc and Furukawa are both credible, long-established brands. The question worth asking instead is: which design philosophy suits your specific operating context?
Epiroc's Solid Body (SB) series, introduced in 1993, built its reputation on a single structural idea: integrate the percussion mechanism and guide system into one piece, eliminating the conventional three-part body held together by through-bolts. Fewer joints means fewer leak points, fewer torque-check intervals, and a lighter overall package for the same performance class. The SB design is notably suited to rental fleets and markets where the operator may not be a trained technician — the floating lower bushing can be replaced on-site with standard hand tools, and no special adaptor fittings are required for service.
Furukawa's FX series reached the same conclusion from a different direction. Their mono-block design without through-bolts was developed specifically because through-bolt fatigue and failure had become a recognized maintenance cost driver across the industry. The FX body adds a replaceable cylinder liner — a feature absent from Epiroc's SB design — which allows the wear surface inside the cylinder to be swapped without replacing the entire body. A higher back-head pressure and larger piston diameter deliver 20–30% more impact energy over previous models at the same hydraulic input. For quarry and hard-rock primary work, that efficiency gain directly reduces fuel consumption per tonne broken.
Head-to-Head: Seven Dimensions That Actually Decide the Purchase
The table below compares Epiroc and Furukawa across the seven dimensions that most often determine which brand a contractor or fleet manager selects in practice. The 'choose when' column gives a direct decision steer rather than restating features.
|
Dimension |
Epiroc |
Furukawa FX |
Choose when… |
|
Design lineage & body architecture |
Solid Body (SB series): percussion mechanism and guide integrated into one piece since 1993 — eliminates the front-head/cylinder/rear-head bolt assembly that conventional designs require. HB series retains traditional body architecture for heavy mining class. |
FX series: square mono-block body without through-bolts; replaceable cylinder liner; dust intake prevention system with grooves that trap contaminants on the upstroke and expel them on the piston downstroke. QUICK SWITCH VALVE (QSV) allows Short/Long stroke and Blank Prevention mode by a 90° turn. |
Epiroc SB for compact and mid-range work; Furukawa FX mono-block architecture for sites where through-bolt maintenance is a recurring cost problem |
|
Impact energy & frequency range |
SB series: 550–2,300 BPM (maintenance-free high-pressure accumulator). HB series extends to mining-class energy. Energy Recovery technology standard across the range — returns recoil energy to the piston return stroke. |
FX275 Qtv: 20–30% impact energy increase over previous models via higher back-head pressure and larger piston. FX770: 10% higher impact than predecessor at same operating pressure/flow. Impact rates 250–800 BPM depending on model. |
Epiroc for very high-BPM concrete/demolition; Furukawa FX for applications where impact energy per blow is prioritised over cycle rate |
|
Carrier weight range coverage |
SB series covers micro excavator through 24 t (9 models, 55–1,060 kg service weight). HB series covers larger mining carriers. Total range spans 0.5 t upward. |
FX series covers 1–83 t (FX770 upper limit). Fx15A for micro excavators; Fx770 for 48.5–83 t machines. 'Switch Hitch' side-plate system for backhoe compatibility without separate OEM brackets. |
Both cover the full carrier range; Furukawa's Switch Hitch is a practical advantage for rental fleets running mixed carrier brands |
|
Maintenance access & field serviceability |
SB floating lower bushing: replaceable on-site with standard hand tools without special equipment. ContiLube II auto-lube option. No special tools or adaptor fittings required for service. |
FX: replaceable cylinder liner (on-site swap to restore alignment); accessible accumulator on Qtv models; inline grease fitting with improved internal routing. Pro-Pak includes all installation hardware at point of sale. |
Both prioritise field serviceability; Epiroc SB's 'no special tools' claim is notable for rental fleets and markets with limited dealer support |
|
Noise & vibration control |
SB Solid Body design is inherently more compact than conventional equivalents, reducing vibration transmission to carrier. Integrated water nozzles optional on SB 152–SB 1102 for dust suppression at source. |
Qtv cradle: combined noise suppression and vibration dampening enclosure. ST-Box ultra-low noise specification available. Mono-block body design based on vibration mode analysis reduces structural resonance. |
Furukawa Qtv for sites with active noise regulations; Epiroc for sites prioritising dust suppression alongside noise control |
|
Service network & parts availability |
Epiroc: direct successor to Atlas Copco's breaker division; established dealer network across mining, construction, and quarrying markets globally; strong parts logistics for HB and SB series. |
Furukawa Rock Drill: founded 1875; 140+ years in rock excavation; dealer network concentrated in Japan, North America, and selected Asian markets. Pro-Pak standard kit eases initial setup at any dealer. |
Epiroc has broader global dealer coverage; Furukawa stronger in Japan and North America; parts for both are available through third-party OEM suppliers in all major markets |
|
Best-fit application summary |
Urban and indoor demolition, foundry cleaning, tunnelling, applications requiring dust suppression, high-frequency concrete work, rental fleet deployment where serviceability without specialist tools matters. |
Quarry primary and secondary, hard-rock road/bridge breaking, pedestal breaker installations, applications where through-bolt maintenance has historically been a downtime driver, North American contractor fleets. |

The Decision Most Buyers Actually Face
In practice the choice between Epiroc and Furukawa rarely comes down to raw performance data, because both brands comfortably exceed the requirements of most applications in their respective carrier weight classes. The actual decision usually hinges on three things: dealer proximity, parts logistics, and the maintenance skill level available on site.
For hard-rock quarry and mining applications where impact energy per blow is the primary productivity driver, Furukawa's FX series and the higher-pressure backhead designs consistently appear in the same conversation as the larger Epiroc HB series. For urban demolition, foundry cleaning, and indoor breaking where noise, vibration, and dust suppression matter as much as raw power, the Epiroc SB range's compact geometry and integrated dust nozzle option have a genuine advantage. Both observations come from application logic, not from comparing marketing claims.
One factor that belongs in every comparison but rarely appears in brand literature: the QUICK SWITCH VALVE on Furukawa's larger FX models lets the operator switch stroke length and activate blank-prevention mode with a 90° turn of the valve — no tools, no disassembly. On job sites where material hardness varies shift to shift (limestone face in the morning, granite intrusion in the afternoon), the ability to adjust energy mode from outside the cab is a real productivity feature. Epiroc offers an optional Smart Stroke System on selected models that adjusts automatically. Different solutions to the same problem — which one is 'better' depends entirely on whether the operator is on-site to do the manual adjustment or whether automatic adaptation is required.
