There are four types for choosing: Moil, Blunt, Flat, Conical Point. The material is 42CrmoA.Breaker Body:Including Front head, cylinder and back head. Ensure your breaker will be in the best performanceSeal Kit:We can supply both Parker and NOK seal kit which are the most famous brands in the business line.1Superior stability performance, long service life, and low chisel breakage rate.2Alloy steel reinforcement and superheat treatment ensure the quality and performance of the component.3Fewer components, easier maintenance, more convenient excavation work.4TECHNIC: Turning processing is done by Korea Hyundai I WIA and Germany DMG machining center, and grinding is performed by the Japanese TAIYO KOKI vertical grinding machine, which automatically inspects parts and ensures accuracy and precision as much as possible.5Please note: All our hydraulic breakers, especially for the main body-cylinder, are thoroughly tested before shipment. We'll check if the piston vibrates smoothly within and checking for N2 gas-leak.1Mining--Mountains, mining, crushing, secondary crushing2metallurgy--Clearing slag, Demolition of furnace and foundation;3Freeway-highway repair, cement pavement is broken. foundation excavation4Railway--tunnel,bridge,mountain down,subgrade compaction5Construction--Demolition of building and reinforced concrete6Ship repairing--Clearing clam and rust from the hull7Others--Ice breaking, breaking the permafrost and Vibrating Sand11.
