Tapered Hard Stone Drilling Bits 7 11 12 Degree Button Drill Bit For Mining
Rock Drilling Bits Product Information:
This drill bit is well matched with small and medium rock drilling rigs. It adopts qualified cemented carbide and alloy steel to ensure stable performance and long service life in harsh working conditions. It can meet different drilling demands and is widely used in mining quarrying tunnel water conservancy transportation and infrastructure construction.
Rock Drilling Bits Operating Method:
Designed to deliver both impact energy and rotary power from the drilling rig directly to the rock formation, this drill bit operates with high efficiency in demanding working conditions. Its cemented carbide inserts deliver repeated, high-frequency impact to crush and fragment rock effectively, while the heavy-duty alloy steel body maintains structural integrity and consistent performance. This integrated design delivers reliable drilling speed, smooth hole quality, and long-term durability across a wide range of geological conditions.
