When breaking Concrete, the breaker is expected to penetrate the material, allowing it to crack and shake loose from the reinforcing steel. High frequency breakers tend to provide better performance in this application as it is not the energy per blow, but the fast blow rate that destroys the concrete's structural integrity. We recommend on concrete walls, footings, and floors to use a 750 - 1,500-ft. lb. breaker. With larger projects, consisting of large footings greater then 4 cu. yards, use a 2,000 - 5,000-ft. lb. breaker. The high production demand of bridge and building demolition requires a 7,500 - 10,000-ft. lb. breaker.

Yes. There are times where not only different styles of breakers are used but different brands as well. They all function very similar and can be placed into the same box without issues.

Looking for some spare parts for this hammer drill...Is there any kind of web store or whatever that can ship worldwide spare parts for this machine?


It is very hard to find parts for tools made in China. There are many look-alikes all with different names. They could, however share parts. If you look on ebay searching "sds roto hammer" you will see many hammers that look similar, different colors. Take a look at the hammer listed below. It is a harbor freight tool. The parts may work. If you have harbor freight in your city, take a look (or on ebay). To order parts for harbor freight tools, look at manual for tool selected, there will be an 800 number to call.

Breakers Troubleshootinf


When breaking oversize material the breaker is expected to break the material down the middle into two pieces. This is optimum production. If the operator has to re-position the breaker towards the edge of the rock and gradually downsize the material, production rate slows down. To assess what size of breaker will effectively handle this application, the size and hardness of the material must be known. If a 4 cu. yard piece of hard rock (20,000 psi or greater) needs to be broken in half you will require a 7,500-ft. lb. or larger breaker. If a 2 cu .yd. piece of limestone (20,000 psi or less) needs to be broken in half you will require a 3,000 - 5,000-ft. lb. breaker.

Breakers Question


This is the most critical factor in choosing the breaker size. SMALL HYDRAULIC BREAKERS (HAMMERS): up to 1200-ft.lbs. (1627 Joules), are typically used in concrete and other light duty work. MEDIUM HYDRAULIC BREAKERS (HAMMERS): 1200 - 4000-ft.lbs. (1627 - 5423 Joules) are used in both concrete and rock applications with limitations on the size and amount of material to be broken. LARGE HYDRAULIC BREAKERS (HAMMERS): over 4000 ft. lbs. (5423 Joules), are typically used in rock and large scale concrete demolition projects.

Breakers advice


When trenching, the breaker is expected to fracture a solid mass of rock into manageable pieces. The size of the material could be 100's of cu.yds, and the energy will be quickly absorbed. This is why it is recommended to work from a bench so the rock has somewhere to break out. We recommend when trenching in limestone or medium hard rock, to use a 3,000 - 5,000-ft. lb. breaker. When working in hard material we recommend a 7,500 - 10,000-ft.lb. breaker, and if high production is critical, a 13,500-ft.lb. breaker would be beneficial.
