Step-Type Drag Bits Of Three-Wings And Four-Wings For Water Well Drilling
Product Introduce
3 wings step drag bits are economical tools when drilling softer geological formations and shallower depths, they are primarilydesigned for soft tomedium formations, such as Clay, Loam, Silt ,Mostsoft-to-medium soilsthat have some moisture, etc. And also step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.
Adavantages
1.High penetration rate
Drag bit are manufactured from forged high quality alloy steel and premium tungsten carbide insert, plus state of art welding technology and multiple precision heat-treatment to provide highest penetration rate and longest lifespan at roughest condition.
2.Long Service Life
all tungsten carbide tips are silver soldered to the bit wing by a special process to ensure a strong bond that will not shear or break when drilling through hard rock. All bits are one piece construction of alloy steel forged or cast with tungsten carbide cutting tips and gauge sides to insure long life.
