The RMT 120FZ Pneumatic Drifter is the underground-focused variant of the BBC 120F series — a direct OEM equivalent to the Epiroc BBC 120FZ (formerly Atlas Copco BBC 120FZ).
While the RMT 120F is primarily used for surface drilling, the RMT 120FZ is engineered and specified for underground applications — differing in a few key parts and the retainer locking system to suit the demands of longer underground operations. All other major components and spare parts are identical and fully interchangeable between the two models.
Weighing 71.5 kg, the 120FZ delivers the same core performance — 35 Hz impact rate, 7.2 kW maximum impact power, 210 RPM rotation speed, and 167 l/s (354 cfm) air consumption at 6-7 bar.
Its hole capacity extends to 51-64 mm (up to 30 metres depth) and 64-89 mm (up to 15 metres), with R32, R38 and T38 drill rod compatibility.
Like its sibling model BBC 120F, it also comes with the eight-pawl, rifle-bar rotation motor and remote-controlled reversible rotation.

The RMT 120FZ iis built only to work only for the most demanding underground drilling — long hole drilling, ring drilling, face drilling and drifting in underground mines, grouting holes for surface mining, and construction tunnelling.
It is mountable on the Simba Junior Long Hole Drilling Rig, Wagon Drills, and Crawler Drills.
The RMT 120FZ offers the same performance as the Epiroc BBC 120FZ, with 100% interchangeable spare parts, at a significantly more competitive price and faster delivery. It is supplied directly from the manufacturer with no distributor markup.
For operations in Peru, Colombia, Chile, Mexico, South Africa or any country currently running Epiroc BBC 120FZ drifters, the switch to RMT 120FZ units is very simple: - the same rig mounts, same spare parts, and same service procedures.

Maximum torque is rated at 665 lb-ft (900 Nm), ensuring the drifter handles the hardest rock types without slipping rotation. Backed by a 6-month replacement warranty on any kind of manufacturing defects, with support of spare parts from the direct manufacturer.
The power, performance, availability, and price are almost the same in both tools. The spares parts are also 90% the same. The major difference is the retainer locking system.
In the BBC 120FZ, the side bolt is longer, which is attached to the retainer. This gives the tools better stability while performing deep underground drilling.
The Atlas Copco BBC 120FZ is an optimised version for underground mining operations. And the 120F is a versatile version which is used in both underground and surface drilling.
Both the tools can be mounted in the same drilling rigs.
