The Epiroc SB 202 T is the tunnel version of the SB 202 Solid Body hydraulic breaker, built for scaling, wall and roof profiling and other underground work on 5,500–13,200 lb (2.5–6 t) carriers. Service weight is 440 lb (199 kg) with a 2.56 in. (65 mm) working tool and 13 in. (330 mm) working length. Exchangeable restrictors match the breaker to the job: 850–1,800 bpm tunneling, 1,250–1,700 bpm scaling; operating pressure 1,450–2,175 psi (100–150 bar) tunneling, 1,450–1,595 psi (100–110 bar) scaling; oil flow 9.2–17.2 gpm (35–65 l/min) tunneling, 10.6–18.5 gpm (40–70 l/min) scaling; max hydraulic input 22.8 HP (17 kW) tunneling, 17.4 HP (13 kW) scaling.

Tunnel-specific details include a press-fit bushing locked by an extra pin to limit bore wear, an exchangeable wear plate, integrated nozzles for water spraying, and a special working tool with front shield and dust cover to limit dust intake. The Solid Body concept integrates the power cell and breaker box in one body and eliminates common parts for a slim, compact, lightweight design, energy recovery feeds piston recoil back into the blow, and the maintenance-free high-pressure accumulator and integrated pressure relief valve protect the breaker from overloads. Current and earlier tunnel tool sets are under Epiroc working tools; see the full Epiroc hydraulic breakers range.
