Genuine Bosch 1500 W heavy demolition hammer — 11 kg class with high-impact energy for sustained concrete breaking and roadway demolition across NE India.
The Bosch GSH 11 E is a heavy-duty electric demolition hammer weighing 11 kg and rated at 1500 W, designed for sustained concrete breaking, roadway demolition, compacted hardcore removal, and structural concrete busting. It operates in hammer-only mode — no rotation — delivering high-frequency impacts through a hex-shank chisel or moil point. The 11 kg machine weight and high single-blow impact energy mean the GSH 11 E works through reinforced concrete and hard aggregate that would stall or overheat a lighter 5 kg class demolition hammer within minutes.
Multi Trade Combines is an authorised Bosch dealer at AT Road, Guwahati. The GSH 11 E is a standard tool in Northeast India's civil demolition and road maintenance industry — used by contractors breaking concrete footings for building redevelopment, road repair crews removing patch areas of bituminous concrete, and infrastructure maintenance teams breaking up failed culvert headwalls for reconstruction. We supply the GSH 11 E with genuine warranty and stock replacement chisel sets for the hex-shank holder.
Civil demolition contractors working in Guwahati's densely built commercial areas use the GSH 11 E to break out concrete elements for building renovation and structural additions — concrete lintels, floor slab patches, and column bases. The 11 kg machine delivers enough impact energy to progress efficiently through M25 concrete, whereas a lighter hammer would require an operator to exert excessive downward pressure and fatigues quickly.
National Highway and state PWD road maintenance teams use demolition hammers to remove failed or deteriorated concrete pavement patches before relaying. In flood-damage repair work — common across Assam and Arunachal Pradesh after every monsoon — the GSH 11 E breaks up washed-out concrete bridge decks, collapsed retaining walls, and eroded culvert structures for rapid clearance and reconstruction.
Mining and quarry operations in Meghalaya — coal, limestone, and sillimanite extraction — use heavy demolition hammers for secondary breaking of oversize rocks that cannot pass through crushers without reduction. Industrial facility demolition in Guwahati's older industrial belt uses the GSH 11 E to cut through concrete floors and machine bases during plant relayout.

The Bosch GSH 5 is a 5 kg class, 1100 W demolition hammer suited for medium-duty breaking — chipping, joint raking, floor tile removal, and light concrete busting. The GSH 11 E is an 11 kg, 1500 W machine delivering significantly higher impact energy — around 23 joules versus 8 joules on the GSH 5. This makes the GSH 11 E the right tool for sustained concrete slab breaking, roadway demolition, and structural concrete removal where the GSH 5 would labour and overheat. The GSH 11 E uses a hex-shank chisel holder instead of SDS-max, so the chisel range is specific to the GSH 11 E and not interchangeable with SDS-max rotary hammer accessories.
