Round Shank Bits B47K17.5 Bullet Teeth for Foundation Drilling Rig

Best Carbide Tips + Master of Brazing
Kellyway bullet teeth is using the best high coarse carbide tips to ensure the tops durability in the tough working situation. The high coarse structure’s better heat conduction ability helps to reduce the bullet teeth working temperature.

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.

You can expect longer working time and less premature wear-out and break failure.

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.
