What is a Tapered Rod? Most People Get This Wrong
In the field of coal mine drilling, the Tapered Rod is a highly favored piece of equipment due to its unique structure. It is commonly referred to as Tapered Drill Rods, Integral Drill Rods, or Plug Hole Rods. Unlike traditional round rods, it features a triangular arc steel tube body with a tapered transition, making it more stable and durable than standard rods.

KSQ Drill can produce as your request of carbide size, different length of tapered rod.
The tapered rod is primarily used in the coal mining industry, especially for drilling in coal seams and areas close to coal layers. It is commonly used in critical operations such as water exploration and gas drainage in coal mines. Additionally, it is suitable for tasks like anchoring and drilling in geophysical exploration and hydraulic engineering projects. With its strong adaptability, it is a reliable tool for drilling in various fields.
