Anchor drill bits
Ground or rock anchors (also referred to as soil nails), Mainly used in drilling anchor nets support holes in coalfields, in mines for drilling holes for roof-bolts, providing a powerful guarantee for efficient roadway excavation.
Anchor drill bits
Ground or rock anchors (also referred to as soil nails) involve the drilling of a small diameter hole (horizontally, vertically or on an angle) using a top head drive rotary rig. Usually a single steel bar is then grouted centrally throughout the length of the hole, and locked in place with a plate and nut.
Anchors can be installed at equal centers on a certain surface to increase stability, or as foundations for a small building.
Features:
1.Made by diamond cutting tooth, higher drilling speed and longer life in soft and medium-hard formations.
2.Wear-resisting blades, need no repeated grinding.
3.With no hole shrinkage, high pore-creating rate.
4.OEM and many years manufacturing experiences.
Mainly used in drilling anchor nets support holes in coalfields, in mines for drilling holes for roof-bolts, providing a powerful guarantee for efficient roadway excavation.
It can reduce the cost and enhances the efficiency obviously and drastically, avoiding wasting of bulk explosives and anchor bolts, improving the efficiency of construction and alleviating workers' labor strength and save the man-hour. They adopt high quality cutters and advanced brazing technology, therefore, they have high wear ability and solid performance.
We can also supply the made-to-order productions according to your detailed specifications.
