Henglong Rock Tools offers durable, high efficiency 54mm T35 threaded button bits for top hammer drilling. Engineered for quarrying, underground mining and rock bolting, this carbide drill bit delivers stable penetration and a longer service life for medium hard rock conditions.
Featuring a high toughness alloy steel body and premium tungsten carbide ballistic buttons, our 54mm T35 bit performs reliably on granite, limestone, sandstone and fractured rock formations. The standard T35 thread ensures a firm fit with matching drill rods, transferring impact force efficiently for consistent drilling results.
We target common industry points such as carbide breakage and premature bit failure. Strict quality control minimizes rework and extra operational costs, helping clients reduce long term drilling consumable expenses.

With moderate weight and easy operation, the 54mm T35 bit is more adaptable than larger T38/T45 bits for limited working spaces and medium-depth drilling projects.
