The Apafor® 450 is the most widely produced model, renowned for its ease of use and maintenance as well as its ability to reach 60-80 metres (depending on the terrain and diameter) according to the different drilling techniques possible, and therefore meets the majority of requests, with some users reaching even greater depths! All this while remaining compact! Its design allows it to work in difficult conditions, in very hot, dusty or very humid environments, but also in sub-zero temperatures. Its low centre of gravity gives it excellent stability even on sloping ground.

This drill rig can therefore perform all types of core drilling, as well as rotary drilling, augers, down-the-hole hammering and optional off-hole roto-percussion (hydraulic hammer). It can perform vertical and inclined drilling and is fully autonomous with its basic options (including built-in hydraulic injection pump, manoeuvring winch and hydraulic carriage retraction). It has a multitude of other options to best suit different needs.

The range of torques and speeds is extensive thanks to their efficient rotation motor and proportional hydraulic controls. Different rotation heads can be offered if the activity is more focused on core drilling (High Speed Head) or on auger or rotary drilling (Heavy Duty Torque Head), although the standard rotation head offers an excellent torque to speed ratio to successfully implement the different drilling methods.
