Mammoth Shock Sub

Product Description

The Mammoth Sealed Shock Sub is designed to reduce vibration and shock by absorbing these energies from being transferred to the powerhead during rotational pulldown and pullback operations.

Mammoth Sealed Shock Subs are manufactured from superior quality materials and are subjected to specific heat treatment processes to maximize the lifespan of the tooling & increase drilling productivity.

Price Excludes
  • Installation by Mammoth Technician
  • Spare Parts
  • Duties and Taxes
  • Freight and Insurance

Mammoth Shock Sub Benefits

The Mammoth Shock Sub is designed to address
  • Wear and tear on conventional shock sub systems
  • Multidirectional absorbency limitations
  • Inadequate seal characteristics
  • Need for enhanced safety features
Drill Rig Benefits
  • Reduces drill rig maintenance by dampening torsional and axial shock loads.
  • Increases penetration rates by keeping the bit in more uniform contact with ore formation.
  • Allows use of higher pull-down force and increased rotary speeds in demanding drilling areas
  • Increases bit life by dampening repeated shock loads normally transmitted to the bit bearings & cutting structure
  • Decreases noise levels by eliminating metal to metal contact between rotary drive & drill pipe
  • Rotary and DTH compatible

All Mammoth Shock Subs are based on a standard shoulder to shoulder length. Mammoth Shock Subs are not restricted to standard shoulder to shoulder lengths, as we can customize the shoulder to shoulder dimension according to client specifications.

It is recommended that only genuine OEM spare parts and consumables are used on the Mammoth product range, to ensure full performance and operational stability. Utilising unauthorised spare parts and consumables can result in injury and potentially void warranty claims.
