Full Size Tungsten Carbide Inserts Three-Wing Drag Bits for Soft Drilling
Product Introduce
Drag drilling bit also named blade bits, with a Tungsten Carbide inserts on the blades.They are usually designed for use in soft formations such as sand, clay, or some soft rock.Their uses include drilling water wells, mining, geothermal, environmental and exploration drilling.Whenever possible, they should be used to drill pilot holes, for they produce cuttings are easiest to log.Normally drag bits are 3 wings, but we can make 4 wings following your drawings or samples. Many special designs are available upon your request.
Adavantages

resistance.
2. Parabolic crown profile and maximise junk slot area can clean
bie better,and prolong the bit working life.
3. Non-symmetry blade arrangement enhances drilling well balance.
4. Opetimization for cutter shape, slant angle, cutter numbers
prolong the cutter working life in combination with high quality
cutter, and improve ROP and drilling efficiency.
