The YN27C Gasoline Rock Drill is a highly efficient, hand held portable rock drill machine powered by a 2-stroke petrol engine. Weighing 27kg, it operates independently and requires no air compressor and no electricity. It is widely used as a reliable rock drilling solution for sites without power or air supply.
Quarry drilling: Ideal for granite, limestone, and marble extraction.
Small-scale mining: Perfect for exploratory drilling and secondary breaking.
Road and bridge construction: Used for asphalt breaking and concrete tamping.
Remote operations: The go-to rock drill without compressor for mountainous areas and emergency rescue sites.
True Portability: Operates entirely on gasoline mixed with lubricating oil. No heavy hoses or cables.
Multi-functional Design: Easily switch between drilling mode and breaking mode.
Deep Drilling: Capable of drilling boreholes up to 6 meters vertically downward (28mm-42mm diameter).
Rugged Build: Designed to operate in high-altitude, cold weather, and harsh outdoor conditions.

In remote quarrying sites without electricity, the YN27C is the perfect companion for our HSCA (Expansive Mortar). Use the YN27C to drill precise boreholes, then pour our 120MPa soundless cracking agent into the holes for a safe, non-explosive rock breaking solution. We also supply professional tapered drill bits and rods matched for the YN27C.
Q: Does the YN27C need an air compressor?
A: No. It is a fully independent internal combustion machine with its own built-in petrol engine, requiring zero external air supply.
Q: What fuel mixture does the YN27C use?
A: It requires a mixture of standard gasoline (petrol) and 2-stroke engine lubricating oil, typically at a volume ratio of 12:1.
Q: Can the YN27C break concrete?
A: Yes. By switching to the breaking mode and installing a moil point or flat chisel, it easily crushes concrete and asphalt.
Q: Where is a gasoline rock drill used?
A: It is mainly used in quarrying, mining, road construction, and remote engineering sites where air compressors and electricity are not available.
