Joysung TDG50 Line Boring is a lightweight, portable, line boring machine, it can be adapted to variety of the narrow space, high-altitude complex processing needs. It combines our Joysung more than 15 years of experience on site engineering service, advanced industry design concept and field boring capability.

Boring Diameter: 55-300mm(standard)    38-300mm(optional)


  • Integrated rotation drive unit and automatic feed unit.
  • Equipped with bore cutter measuring and diameter measuring ruler.

Lightweight construction, performance excellence

Gearbox Unit

Integrated rotation drive unit and auto feed unit together creatively, only 9.5Kg, more portable, step less Speed regulation range 0 to 0.5mm, easily achieve the forward and reverse exchange.

Easy Set Up

Equipped with 3 legs mount kit, which can be adjusted to different angle, to meet different holes.

Measuring tools

Equipped with bore cutter measuring tool and diameter measuring ruler.

Drive Power Unit

Standard drive unit is 1800W electric motor. Max cutting depth can reach to 6mm.

Superior scalability

  •  Optional one Ø38mm boring bar to achieve boring diameter from Ø38mm to 300mm.
  •  Optional facing head, to achieve face processing of pipe and flanges.
  •  Optional bore welder used for integrated line boring and welding system.


This machine with powerful machining capacity which widely service for many fields, repairing holes in heavy construction equipment, such as cranes, excavators, bulldozers, tractors, back holes etc.
