Drilling buckets are mainly used for drilling water-bearing sandy soil, sludge, clay, muddy sub clay, sandy gravel, cobble, and weathered soft formation. The bucket can be designed into cylindrical type and conical type according to bucket diameter, type of drilling rig and soil conditions. The welding angle of bucket teeth can be designed according to formation conditions so that the drilling buckets can keep high efficiency of soil cutting amount in any formation conditions.
The bottom cover is made of high-strength Mn plate, and the cutting edge includes single-layer type and double-layer type; the soil inlet also includes single-bottom type and double-bottom type. rock drilling bucket is one mostly using type of buckets for customers abroad.
Unique Drilling Bucket & Core Barrel adopt the high-carbon steel (Q345B, 16Mn, Q195-Q345, etc.) and special drilling bits (B47K20H, B47K19H, B47K17H, 3050, 3060, 3065,C30, C31HD, B85, B43H,18TL, 18HD, 25VIP, 18VIP, 25T, 25HD, 22T,833-18,855 25,18PN/LK,25PN/LK ) angle to keep the drilling strength and efficiency.
