Buying equipment that sits idle between jobs is a costly mistake. The JK820 is built with versatility at its core — swap out the hammer and bit combination, and this single rig handles quarry blasting holes, water well drilling, slope anchoring, and foundation rock work. With a 90mm to 138mm hole range and 20-30m depth capacity, it covers the most common drilling tasks on a construction or mining site without needing multiple machines.
90-115mm blast holes in limestone, granite, and basalt. Matched with the right DTH hammer, the 820 bpm impact frequency delivers clean, straight boreholes.
Expand to 138mm for medium-depth wells. The hydraulic feed system maintains consistent pressure through alternating layers of rock and soil.
Road slope anchoring, foundation rock breaking, and small-scale excavation. The crawler chassis positions precisely on uneven terrain.
