Pionjar 120 Petrol Rock Drill

Description

The Pionjar 120 Petrol Rock Drill, commonly supplied as the YN27C, is a multifunctional handheld machine suitable for rock drilling, breaking, splitting, tamping, digging and chiselling. Its self-contained design makes it particularly useful in remote areas where electricity, compressed air and a permanent water supply are unavailable. The machine uses an integrated single-cylinder, air-cooled, two-stroke petrol engine to power both the drilling and impact mechanisms. It supports drilling diameters of approximately 28–42 mm and can drill vertically downward to a maximum depth of approximately 6 metres, depending on the rock condition, drill rod and operating method.
