The T51 89mm Flat Face Standard Body Ballistic Button Bit is a top hammer threaded rock drill bit engineered for demanding rock drilling operations. It features a T51 threaded connection, an 89mm drilling diameter, a flat face design, a standard body profile and ballistic tungsten carbide buttons.
The ballistic button configuration delivers an effective balance between rock penetration rate and wear resistance, making this drill bit well suited for medium-hard to hard and abrasive rock formations. The flat face design is widely selected for hard and abrasive ground conditions, especially where high-pressure flushing and stable drilling performance are required.
The T51 89mm button bit is compatible with T51 extension drill rods and top hammer drilling systems, and is commonly used for bench drilling, quarrying, mining, underground long-hole drilling, construction and rock excavation projects.
