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.

Double bottom rock bucket: pebbles, gravel layers, moderately weathered soil-like soft rocks, such as moderately weathered argillaceous sandstone, argillaceous conglomerate, etc. In case of harder rocks with higher weathering degree, such as fully weathered and strongly weathered granite, etc., core barrel and spiral auger are often used together.
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.

Customized Drilling Buckets
(1). Kelly Box: design various type (Buaer, etc. ) and size 130*130, 150*150,200*200 or as required ) kelly box based on demand.
(2).Shell Height: design as demand, according to the piling diameter and soil condition prolong or shorten, increase of efficiency by drilling more.
(3).Cutter: single cutter or double cutter and single bottom or double bottom design as demand;
(4).Bottom Open Mechanic : half-automatic or manul mechanic bottom open system.
(5).Model of Teeth:
Rock Bits:B47K20H, B47K19H, B47K17H, 3050, 3060, 3065,C30, C31HD, B85, B43H, etc.
Clay Teeth:18TL, 18HD, 25VIP, 18VIP, 25T, 25HD, 22T,833-18,855, etc.
Roller Bits: IADC 637/635, IADC 617/615, IADC 537/547/535, IADC 136/137 etc..
