This 2019 Junjin JD800ENC is a used vertical drill — sometimes referred to as a crawler drill or rock drill — a type of machine used for down-the-hole and rotary percussion drilling in mining, quarrying, construction, and geotechnical applications. Junjin is a South Korean manufacturer with a long-standing presence in the drilling and construction equipment industries, known for producing hydraulic drilling rigs and concrete pumping equipment.
Power comes from a Cummins QSB6.7 Tier III diesel engine, serial number . As a Tier III machine, it operates without DEF fluid and without a diesel particulate filter regeneration system, which is a practical advantage in remote or demanding site conditions where emissions aftertreatment maintenance can be a complication. The machine was built in December 2018 and placed into service in August 2019. An extended Cummins warranty was in place through August 2024 or 10,000 hours, whichever came first.
The machine shows 3,603 total engine hours since new, with 1,161 percussion hours recorded. The YH80A hydraulic drifter was recently rebuilt at 3,283 engine hours and 1,086 percussion hours, meaning only 75 hours have accumulated on the drifter since that rebuild — a significant point for buyers evaluating remaining component life.
Standard attachments and configurations include a rear winch, rear leg outrigger, extendable boom, rod changer, dry dust collector, and water injection system. The combination of dust collector and water injection provides two complementary methods of controlling drill cuttings and airborne particulate at the hole. The machine is located in Kentucky, USA.
