Geological spiral drill drill ribs aka brief introduction: Geological spiral drill is our company on the basis of geological drill high-torque performance on single or double helical blade helical blade, the prestressed winding process machining and welding. Diamond club dedicated body of high quality geological steel pipe, drill pipe joints made of high quality alloy steel, tempered by the true air conditioning, greatly improving the fatigue strength and shear strength. The use of advanced production technology of friction welding, drill with high bending strength, welding firm characteristics. Full use of advanced production equipment, CNC machining equipment, high production efficiency, quality and stability characteristics. To ensure the requirements of straightness deep hole drilling. Ultra-helix spiral blade design makes the product has torque, slagging speed, good drilling molding, easy sticking characteristics. Particularly suitable for the bad effects through the water slagging coal and soft coal and rock class deep drilling. Diameter Φ73 following geological spiral drill pipe, with a variety of supporting the use of hydraulic drilling rig directly using clamp drill rig directly conduct drilling and replacement of the outer spiral drill pipe, convenient, greatly reducing the labor intensity of the operator. Drilling in the ultra-high pressure soft seam conditions, the use of construction techniques when drilling units, the choice of large diameter spiral geological drill 90,113,133,146, convenient installation to achieve the core pipe laying. Material: Geological auger club dedicated body of high quality geological steel pipe, drill pipe joints made of high quality alloy steel Features: 1, drill with high bending strength, welding firm characteristics; 2, high production efficiency, quality and stability characteristics 3 ultra-low-helix spiral blade design makes Geological spiral drill with a torque, slagging speed, good drilling molding, easy sticking characteristic feature: the ability to ensure straightness requirements Specification No. deep hole drilling diameter the length of the production process and thread forms rig connection form grade material 1 Ф50-42 500 ~ 1500 tapered thread friction welding clamp cylindrical DZ50 45Mn2 2 Ф63.5-42 500 ~ 1500 tapered thread friction welding clamp cylindrical DZ50 45Mn2 3 Ф63 .5-50 500-1500 tapped friction welding clamp cylindrical DZ50 45Mn2 4 Ф73-50 500 ~ 1500 tapered thread friction welding clamp cylindrical DZ50 45Mn2 5 Ф73-63.5 500 ~ 1500 tapered thread friction welding cylindrical holder R780 36Mn2v 6 Ф90-63.5 500 ~ 1500 tapered thread friction welding with active drill R780 36Mn2v 7 Φ98-73 500 ~ 1500 square friction welding connection with the initiative to drill R780 36Mn2v 8 Ф110-63.5 500 ~ 1500 tapered thread friction welding with active drill R780 36Mn2v 9 Ф130-63.5 500 ~ 1500 tapered thread friction welding with active drill R780 36Mn2v 10 Ф146-73 500 ~ 1500 tapered thread friction welding with active drill R780 36Mn2v
