One of the notable advantages of submarine hammer drilling is its efficiency in penetrating tough materials. Traditional drilling methods may struggle with hard rock formations, often resulting in slower progress and increased operational costs. Hammer drilling wears less on the drill bit, ultimately reducing the frequency of replacements and downtime.

Bullet teeth are specialized cutting tools utilized primarily in auger operations for drilling through tough soil, rock, and other challenging materials. Characterized by their streamlined, conical design, these teeth are engineered to penetrate efficiently and minimize the required drilling force. Their unique shape allows for optimal cutting performance while maintaining durability in demanding conditions.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
