Description

The U400 ‘Big Shot’ Underground Piercing Tool is a premium pneumatic tool designed for efficient underground installations in water, gas, and cable/fibre optic projects.

Crafted to the highest standards, it is CNC machined to exact tolerances from solid billet nickel chromoly steel and fully heat treated for superior strength and durability.

With features like a replaceable cartridge-style shock absorber, flexible air tube assembly to minimize internal deflection, and a barrel bored design from solid steel, the U400 ‘Big Shot’ delivers exceptional performance with reduced maintenance.

Backed by a warranty and excellent customer support, it is the ultimate choice for reliable moling operations.

Detailed Specifications:

  • Material: CNC machined from a solid billet of nickel chromoly steel; fully heat treated
  • Coating: Anti-corrosive phosphate coating on pistons for enhanced wear resistance
  • Shock Absorber: Easily replaceable cartridge-style shock absorber
  • Air Assembly: Flexible air tube assembly minimizes internal deflection
  • Design: Barrel bored from solid steel (not tubing)
  • Available Sizes:
    • Available in 2″, 2.5″, 3″, and 4″ diameters
    • Example (4″ Model):
      • Weight: 108 lbs
      • Length: 59″
      • Air Consumption: 75 CFM @ 80–100 PSI

Key Features & Benefits:

    Precision CNC machining and full heat treatment ensure robust construction and longevity, even under high-impact conditions.
  • Low Maintenance:
    The design eliminates wear rings and features a replaceable shock absorber, significantly reducing maintenance costs.
  • Optimized Performance:
    A flexible air tube assembly minimizes internal deflection for consistent, efficient operation.
  • Versatile Options:
    Available in multiple diameters to suit various underground installation needs, with a full line of accessories available.
  • Warranty & Support:
    Comes with a warranty and is supported by excellent customer service.

Applications & Industry Uses:
Moling is the fastest, easiest, and most cost-effective method to install sub-ducts beneath sidewalks, driveways, and roads. The U400 ‘Big Shot’ Underground Piercing Tool is ideal for water, gas, and cable installations in underground projects. It is typically hired out as a complete kit, including all necessary hoses, an in-lubricator, and a magnetic level, with lubrication available separately in 1-litre or 5-litre bottles.
