MATE Trepanning System

  • Reduce digging and shoring operations
  • Faster, smoother cutting

The MATE trepanning systems offers EOD teams are more flexible approach for coring munitions.  It is designed to act as a replacement for older trepanning systems to cover any ‘capability gap’ as they are phased out of service, and to allow the deployment of a cutting system where hydro-abrasive systems may present an unacceptable logistical burden.

Reduces the need for digging and shoring

Unlike current in-service systems it does not require access to the circumference of the device.  Instead it utilises the Monica vacuum system, therefore requiring only a portion of the munition to be visible (300x400mm). This reduces the need for digging and shoring operations, meaning less disruption to civilian or military operations.

A hydraulic or pneumatic motor is used to power an annular (hollow) cutter to allow the wall of a munition to be breached so that the munition fill can be accessed. Alternatively a cutter may be used to trepan a hole around a fuze pocket allowing it to be removed intact from the munition body.


Powered by either hydraulic or pneumatic motor

Cuts up to 100mm in diameter to depths of up to 50mm

The MATE trepanning system utilises the same cutting technology as the Monica system. The larger cutter will cut up to 100mm in diameter and to depths of up to 50mm, quickly and smoothly. The use of advanced cutters offers a much enhanced performance over conventional trepanning systems. MATE can be operated up to a distance over 1000m.
