Doofor Inc. launched a new version in its DF550/560-series drill. Manufactured with premium quality components and innovative in-house technology, the new DF560L-2M is now the most powerful rock drill available in the Doofor product line, according to the company.
The new Doofor DF560L-2M is a high-frequency hydraulic rock drill, specifically designed for production drilling on the surface, underground and in tunneling applications. The DF560L-2M has superb functionality equipped with two powerful 160-cu.-cm Danfoss OMS-series rotation motors as a standard.
The drifter provides 20-kW percussion power. With DF560L-2M, it is possible to maintain high rotation speed in rock drilling complemented with powerful torque that is needed for example in sedimentary rock drilling. DF560L-2M model is suitable for many types of heavy machinery such as excavator drill attachments, drill rigs and bolting systems.
Optimal maximum hole diameter for the DF560L-2M is 89 mm (3.5 in.) in hard rock, such as granite. With softer rock, a larger hole diameter can be achieved. Furthermore, the model has a very low overhead, just 84 mm from drill center line. Low profile allows closer and deeper drilling, up to the roof and straighter according to targeted line. Low physical profile also gives more possibilities in drill rig design.
The rock drill has a separated flushing head that allows utilization of different flushing media such as water or air, or air-water-mist. As an option for regular type, Doofor has invented a new BLT-flushing head with enhanced, close-fitted properties. It is made of stainless steel and designed for challenging environments to protect the drill especially when water and even cement is used. In operation, the BLT-flushing head prevents water leaking inside the drill and causing damage. Therefore the drill can perform with full capacity with relatively low maintenance costs.
This model is adjustable with R38, T38 and T45 shank adapters and when a BLT-flushing head is used, also female FR28 and FR32 shank adapters are available. For tap hole drilling, the drill can be equipped with heat resistant sealing. DF560L-2M not only complements the company’s existing product line but also enhances the customer’s business for the future.
