Top Hammer Rock Drill H22 7 Degree Tapered Drill Steel Taper Drill Rod for Mining Tunneling Shank Hex 22*108mm
Prodcut information:
The rod body is made of hexagonal hollow alloy steel, and the product is subjected to high-pressure calcination and vacuum overall tempering heat treatment. It is processed and formed by CNC automation equipment to ensure stable and reliable product quality. The product is widely used in mine tunnel support drilling, mine rock drilling, coal mine rock tunnel, bridge excavation and other engineering construction. Reasonable drilling progress should be based on the physical properties and parameters of the actual material of the drill rod in the tunnel support drilling construction, rock drilling, coal mining, bridge excavation and other special environment operations. When the drill rod is used together with the drill bit, the drill rod should be larger than the diameter of the drill rod under normal circumstances. During the drilling process, you should always pay attention to the condition of the drill bit and the drill rod. In case of drilling stuck, holding and other phenomena, you should stop drilling immediately or drill slowly after drilling to ensure that the drill rod does not bend or deform.
