The Apafor® 800 Multipurpose FS300-Explo is a drilling machine created in close collaboration with two other drilling partners to offer the most complete and efficient multipurpose drilling machine (RC & core) on the market. This drilling machine is also suitable for rotary and down-the-hole hammer drilling or auger drilling.

This makes it a "2 in 1" machine, where usually 2 different machines are needed to perform RC drilling on one side and deep core drilling on the other. The standard version is designed for RC drilling to about 400 metres and core drilling to more than 1000 metres (depending on the defined diameters). However, other technical features can be considered for shallower projects and thus lower cost.

There is also a choice of configuration: on a crawler or on a truck (all makes can be considered).

A wide range of additional equipment integrated on the drill rig can be offered, including various hydraulic handling systems for rods and pipes, as well as a number of options including the integration of an RC compressor and/or cyclone on the chassis.


The most complete and powerful multi-functional drilling machine on the market
Truck mounted (any type, tropicalised on request) or crawler mounted
A variety of integrated additional equipment and options for a completely self-contained unit for both RC and core drilling
Several handling systems offering high productivity, operator comfort and safety


Thanks to these unique features, this probe has several possible areas of application:

  • RC air drilling
  • Water/mud core drilling
  • Rotary drilling
  • Down-the-hole hammer drilling
  • Auger drilling.
