Product features

★According to the construction requirements, combined with modern mechanical, electrical and pneumatic integrated technology, using PLC programming control technology, using pneumatic instead of manual, with higher efficiency, good safety performance, automatic design of double head working at the same time, automatic completion of drilling and Reaming, accurate and easy to adjust.

★ Single and double-headed mainframes can be switched between work, single hole operation or double hole at the same time.

★The diameter of the drilled hole and the diameter of the bottom hole can be adjusted.

★ Reasonable structure, accurate positioning, more humanized operation and high work efficiency.

★ With dual high-speed motors, the system is stable, safe and energy-saving, and can be operated by two people at the same time.

★ Energy efficient, easy to operate, and safer. Widely used in stone manufacturers and construction units for mass production.

★ Three-phase 380V power supply is suitable for use at any time and anywhere, and it can be connected quickly.

★The machine head can move freely in the direction of the beam.

★Lock the position of the plate by the principle of air pressure and adjust the speed of the head up and down.

★ According to the design requirements of the curtain wall, it is applicable to the rear-cut anchor bolts of various specifications. Cost-effective, it is more efficient to make two holes at the same time. It is suitable for the mass production of sheet metal manufacturers and the construction of large-scale projects of large and medium-sized projects and construction units.

★Using original motor and customized movement rotor to meet the requirements of high speed and low energy consumption. Stable performance and long service life.

★With toolbox, equipped with various wrenches, inlet valve and various back bolt sleeves

★ There are hole detection gauges and manuals.

★There is a special electronic water valve to control the on and off of the water, which not only achieves the ideal water cooling effect of the diamond bit but also saves water accurately.

★Drilling consumables for use: Corrugated diamond drills of various specifications such as M6 and M8 are used.
