The all new Drilling Grade Carbide Conical Tooth.
Use in Foundation Rock Augers.
Improved carbide grade for longer tooth life, meaning less down time!
Cases for Bullet Teeth
Production Process
1.All the bullet teeth are welded by the automatic welding line for production efficiency. By using heat treatment and welding line integrated method, it only demands one time heating, making the heat disturbing to the carbide tip to the minimum.
2.Use high grade alloy steel , tungsten carbide tip and advanced brazing,technology to produce high quality.Weldable steel is suitable for covering large ares. The material of the steel body adopt the 42CrMo.The tungsten carbide tip adopt YG11C and YG13C.
3.Design all kinds of rotary bits,trenching bits,diaphragam wall cutters,big diameter bushing bits and flat bits according to customers' requirements and geological conditions.
4.Supply the following bits and holder as :
5030,DS-01,DS05,BA24,BA04,BA13,BA50,BA55,BFZ80,BFZ70,BFZ72,BFZ72L, BFZ65,BFZ100. BFZ42JR,BFZ42ZM,WS39,WS20,WB20,WB39,BHR73,B85/2,B43H,W002,B47K-22H,B47K-19H, B47K17.5. BKH32,C31HD,C30, C10,C20, RL09,B47K,3060-22H,BFZ25L,DV25,BTK87,BRV32,BRV03,BKH47,BKH81,BKH28,BTK10,DV9,DV12,BA70-38,BA90-42,SB38JM, SB38JMK, SB42JL, SB42JR, SB38ZM, SB42ZM, RP4-200,C21,DS05,DS01,BRV32,ECT.
Methods used to avoid or reduce slipping phenomenon
A.Before each drilling, rotate the rotary drive clockwise to open the feed port of drilling tool
B.When drilling into the earth, the bucket should not be fully filled. 70% or 80% is great
C.Weld spring steel pate on the worn tooth to extend it
D.Change drilling tool, such as spiral drill tool
These methods should be used accroding to actual situations.
Appropriate method can be used to improve drilling efficiency.
