The drill pipe, also known as the drill pipe, is made of high quality carbide and 55 SiMnMo steel. Conical drill rods are used in granite and marble quarries, gold mines, railways, tunnels, etc. HR series down-the-hole hammer is an ideal drilling tool widely used in energy, transportation, metallurgy, construction and other industries.
Taper drill rods B22
High quality carbide and 55SiMnMo steel
Rock drilling, coal mining and geological drilling
4, 7, 11, 12 degree
1. The integral rod has a single impact energy and the rock crushing energy is low;
2. The weight ratio of the piston to the drill bit is almost 1:1, providing a long effective action time, thereby improving the rock crushing efficiency and prolonging the service life of the drill;
3. The integrator rod performs well in central exhaust and chip discharge, reducing repeated crushing of the rock;
4. The check valve device can be used to drill holes under water.
5.Tapered Button bits (7,11,12Degree), diameter: 32mm-50mm, prompt type: 4 prompts or 7 prompts or 8 prompts, divided into buttons or ballistic tips.
