This air chipping hammer with a buffer spring and an inlet port nut is pneumatic-powered, allowing you to save more effort and work more safely. Its ergonomic handle and non-slip design allow for a tighter grip and easier control. What's more, it doesn't need to consume electricity or fuel, but through compressed air to carry out excavation, demolition, cleanup, and other crushing operations, which saves energy and brings you greater economic benefits. Key Features Made to Last: It is made of high-quality 45# steel, 20CR steel, and aluminum and adopts a high-temperature quenching process, so it boasts high hardness and resistance to corrosion, rust, abrasion, and deformation, meeting high-strength crushing work needs. Excellent Performance: It comes with an impact frequency of 16Hz and an impact energy of more than 55J, applying a powerful impact on the crushing target and making your work more efficient. Effectively Buffering: Its spring comes with excellent elasticity and sturdiness which make it not easy to deform, and play a buffering role so that you can save effort and work safely. Simple Operation: The ergonomic body fits the palm of your hand and the non-slip design allows for a tighter grip and easier control. It adopts downward pressure activation, which makes the work convenient and safe. Pneumatic Power: It does not need to consume electricity or fuel, but works through the compressed air(not included) to make the hammer body into repeated impact movement, which is more energy-saving and money-saving. Sturdy Connector: The threaded inlet port nut ensures tight connections without easily falling off, improving your working safety. Application It is mainly used for crushing operations in reinforced concrete construction, cement, permafrost, ice, soft ores, soft rocks, and road construction. For example, it is suitable for urban infrastructure projects to break the demolition of solid concrete floors and walls, highway and pipeline construction for cutting and breaking the road surface for road repair, quarrying, coal mining, and machinery industry where impact movement is required.

Please note that bits and shovels are not included. 2.The coordination between the tail of the shovel head and the steel sleeve shall meet the requirements. 3.Before work, it is necessary to put in a few drops of pneumatic oil to empty a few times to lubricate the movement before starting work. During operation, add lubricant every 2-3 hours and disassemble and clean weekly. After work, please add lubricating oil and place it properly when it is stopped for a long time. 4.When using, please avoid crushing operations without a drill rod. Use air pressure should be maintained at 5-6kg/cm²
