Description
The Dera Demolisher Big is a heavy duty electric demolition hammer made for breaking hard concrete, floors, walls, tiles, stone, brick, and light road surfaces. It is stronger than the small Dera demolisher because it comes with a bigger motor, heavier body, stronger impact, and better control for long construction work.
This machine is a good choice for fundis, contractors, builders, plumbers, electricians, renovators, and anyone doing serious breaking work in Kenya. It is useful for removing old floors, breaking slabs, opening wall channels, removing tiles, and preparing surfaces before new construction.

Why Choose the Big Dera Demolisher?
The big Dera demolisher is made for jobs where a normal hammer drill is too weak. It does not drill like a rotary hammer. Its main work is to hit hard and break surfaces faster.
It is a better option when you need more impact force for concrete slabs, old tiles, stone, pavement, wall channels, and renovation jobs. The 1800W motor gives it enough power for longer use on site. Kenyan sellers also describe it as a heavy duty machine for medium to large demolition work.
Main Uses of Dera Demolisher Big
The Dera Demolisher Big can be used for:
- Breaking concrete floors and slabs
- Removing old tiles from houses and shops
- Chiselling walls for plumbing pipes
- Cutting wall channels for electrical wiring
- Breaking brick walls during renovation
- Removing cement screed
- Light road and pavement chiselling
- Breaking hard ground during small construction work
This makes it useful for both home improvement and professional site work.
