Rotary hammer innovation The origin of the rotary hammer(https://www.ykhufengtools.com/product/rotary-hammer/) can be traced back to the ancient Stone Age, when humans used stones and sticks to make simple rotary hammers for hammering and processing stone tools. With the development of society, rotary hammers gradually evolved into metal products and became important tools in various craft fields. In ancient times, rotary hammers were mainly used in metal processing, construction, agriculture and other fields. With the advancement of science and technology, the application range of rotary hammers continues to expand, gradually involving modern industries such as machinery manufacturing, automobiles, aviation, and electronics. At the same time, the structure and function of rotary hammers are also constantly innovating to meet the needs of different industries. In the development process of rotary hammers, material innovation has been a key factor in promoting their progress. From the initial stone and wood to later bronze and iron, to modern alloy steel, carbon fiber, etc, the materials of the rotary hammer are constantly upgraded to make it stronger, more durable and more efficient. The structural innovation of the rotary hammer is mainly reflected in the design of the hammer head and hammer handle.
