The concrete drilling and coring machine is mainly used for drilling and coring hardened concrete such as buildings, highways, airports, wharfs and dams. It has the characteristics of simple operation, convenient relocation and accurate drilling and coring. The surface of the core sample is smooth, and there is no accidental damage to the core sample. It is an indispensable equipment for highway transportation departments, construction departments and relevant colleges and universities. The machine meets the standard of gb11818-89 technical requirements for concrete drilling and coring machine.
In addition, the drilling rig can also drill and core other non-metallic brittle and hard materials, such as refractory, ceramics, glass and rock.

7. Saw blade (grinding head) material: artificial diamond
Application method of hz-15 concrete drilling and coring machine:
1. Move the machine to the place where drilling and coring are required, screw four adjusting screws (5) on the base, adjust the machine level, and embed M16 iron expansion bolts on the ground to fix the machine.
2. Install the drill bit according to the size requirements of the drilling hole.
3. Connect the water source and check whether there is water leakage in the drill bit.
4. Turn on the power switch, idle for several minutes, and turn the feed handle to drill.
混凝土鉆孔取芯機主要用作對于建筑、公路、機場、碼頭、大壩等硬化混凝土的鉆孔取芯，具有操作簡單，移機方便，鉆孔取芯準確等特點。芯樣表面光潔，且對芯樣不發(fā)生意外破壞，是公路交通部門、建筑部門及相關大專院校不可缺少的設備。本機符合GB11818-89《混凝土鉆孔取芯機技術要求》的標準。
另外，本鉆機對其它非金屬脆硬材料，如耐火材料、陶瓷、玻璃、巖石也同樣可進行鉆孔取芯。
