Introduction To The Use Of Extension Drilling Tools

Reaming Bit is developed on the basis of absorbing advanced German production technology and integrating the latest research results of our company.

Reaming Bit is developed on the basis of absorbing advanced German production technology and integrating the latest research results of our company. The rod body of the water exploration spiral drill rod is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel belt, which is welded by prestressed winding. The joints are made of high-quality medium-carbon alloy steel, treated with real air conditioning, and formed under high pressure. The water exploration spiral drill rod adopts a square or hexagonal quick connection method. It is automatically locked by a spring pin when in use. It is equipped with a U-shaped or semi-ring anti-off pin, so that the torque of the drill rod can reach the best condition. It is mainly used in conjunction with portable or hand-held drilling rigs. The drill pipe is light in weight, fast in connection, and fast in slag discharge, which greatly improves work efficiency, so it is called high-efficiency spiral drill pipe. This series of products are widely used in the drilling construction of water exploration and gas exploration in coal seams and near coal seams. They are divided into water-passing and non-water-passing types.
Features of water exploration spiral drill pipe:
       1. It has the characteristics of high bending strength and firm welding;
       2. Features of high production efficiency and stable quality;
       3. The ultra-low spiral spiral blade design makes the geological spiral drill pipe have the characteristics of large torque, fast slag discharge, good drilling shape, and not easy to stick.
       4. Light weight (45% lighter than old-fashioned drill pipe).
       5. Fast footage, low dust, no cuttings left after the plumb hole is drilled, and the hole formation is clear.
       6. The buckle connection is convenient and fast, saving strapping materials.
       7. The rod body can be used upside down after being separated from the drill tail, which prolongs the service life.
       8. Good water permeability during wet operation.
       Extension Drilling Tools generally refers to round steel drill pipes, as well as high-efficiency spiral drill pipes. Water exploration spiral drill pipes are made of high-quality steel, wear-resistant and compressive, and have good durability. Good water exploration drill pipes can be used in the completion of drilling. To a great effect.
