YN27A Internal Combustion Rock Drill/Petrol-powered small internal-combustion rock drill/Fast speed and high efficiency

YN27A Internal Combustion Rock Drill

1. Introduction of YN27A internal combustion rock drill

The YN27A internal combustion rock drill is widely used in an internal combustion type rock drill for mining, road construction, quarrying, national defense engineering, etc. The rock drill is easy to operate. The rock drill is suitable for areas with no power supply and no wind pressure equipment and temporary engineering with large fluidity. Especially suitable

2. Features of YN27A internal combustion rock drill

· It is not necessary to replace the internal parts of the machine head, just move the handle as required to operate.

· The machine is easy to operate, saves time and labor, and has the characteristics of fast cutting speed and high efficiency.

· The machine has reached the first-class level of similar products and can be completely interchanged with international similar products.

· Drill holes in the rock, which can be vertically downwards, horizontally upwards less than 45°, and vertically drilled up to six meters.

· The weight of the main unit is only 27 kg, which is convenient to carry. It is suitable for areas with high mountains, no power supply, no wind pressure equipment and temporary projects with large fluidity.

· This machine has wide adaptability in both high mountains and flat land, regardless of the extreme heat of 40° or the cold region of minus 40°.
