Pneumatic handheld drill supported by a stand

Coal tunnel anchor support has outstanding advantages in reforming support effects, reducing support costs, accelerating tunneling speed, reducing auxiliary transportation volume, reducing labor intensity, and improving tunnel section utilization. Therefore, it has been widely valued and adopted by major coal-producing countries in the world, representing an important development direction of national coal tunnel support technology. The frame-supported handheld pneumatic drill is portable. It is safe, explosion-proof, has high torque, has reversal, high speed, small mass, small size, high efficiency, and a structure that can be used for drilling holes for various purposes, such as gas extraction holes, water exploration holes, and anchor support holes. It is widely used in coal, railway, construction, mining and other engineering construction operations. The machine uses compressed air as the source power, with good safety and strong applicability.   Jiangyin Haiyan Machinery Te…
