DF540L

High-performance hydraulic rock drill

Doofor DF540L is a hydraulic rock drill designed for bolting, general excavations, and underground production drilling. The DF540L has a very low overhead, only 82.5mm from the drill center line. The rotation motor of the DF540L can be installed on the right-hand or the left-hand side. The drifter is completely horizontally symmetric so that it can be installed in a variety of positions.

Flushing media can be water or air. The DF540L is an excellent bolting hammer with its low physical length and rugged, powerful rotation mechanism.

The rock drill can be equipped with male R32, R38, T38 and female FR28 and FR32 shank adapters.

This rock drill can be equipped with stainless steel, separated flushing head for underground mining, bolting and grouting (BLT-version).

Optimal maximum hole diameter for the DF540L is 64mm [2 ½”].
