Project Description

TDG50IMP Line Boring

Modular design, easy to set up or remove. It is a preferred tool for repairing earthmoving equipment like excavator, bulldozer, loader, etc. and working with our automatic bore welder to fulfill I.D, O.D or face welding.

Boring Diameter: 55-400mm(standard) 35-400mm(optional)


  • Standard drive power unit 1800W.
  • Equipped with bore cutter measuring and diameter measuring ruler.

Compact and modular design

It could be used in field boring on large scale steel structure , especially for narrow space processing. Fixed can be horizontal or vertical position, Rotational drive unit and feed unit can be mounted anywhere of the boring bar. Feed unit and rotational unit are only 7KG and 5KG each, more portable, step less speed regulation range 0 to 0.5mm, easily achieve the forward and reverse exchange.

Boring bar

High quality alloy structural steel to ensure cutting accuracy due to its high strength and rigidity. Bar length has 3 options:1828mm, 2438mm,3500mm . Customized length can be available…

Drive Power Unit

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

Superior scalability

  • Optional Ø30mm boring bar to achieve boring diameter from Ø35mm to 400mm.
  • Two sizes of facing head to achieve facing diameter from Ø80mm to 450mm.
  • Optional  BW350 & BW360 auto bore welder.

All parts have their own unique advantages and provide guarantee for steady and accurate operation for the whole system.
