T51 retrac button bits are a specific type of drill bit designed for rock drilling applications, commonly used in mining, quarrying, and construction. The designation "T51" refers to the thread type and size of the bit, while "retrac" indicates that the buttons on the bit are retractable, allowing them to move inward into the bit body.
Retrac button bits are favored in rock drilling operations due to their adaptability to changing rock hardness and their ability to withstand demanding conditions. Proper selection, usage, and maintenance contribute significantly to the efficiency and success of rock drilling operations in industries such as mining and construction.
In today's demanding mining and tunneling environments, T51 Retrac Button Bits are the go-to tools for professionals who refuse to compromise on performance, reliability, or penetration rate. Engineered for power, built for endurance, and optimized for precision, T51 Retrac Button Bits deliver superior results in even the harshest rock formations.
If you're seeking next-level productivity, longer service life, and consistent hole quality, T51 Retrac Button Bits are the smart investment for your drilling operation.
T51 Retrac Button Bits are high-performance rock drilling tools used in top hammer drilling systems. Designed for 89mm–127mm hole diameters, they feature a T51 thread system, allowing for strong torque transfer, easy rod connections, and high axial load capacity.
The Retrac body design adds extra reaming capability and prevents hole deviation—making these bits ideal for broken, abrasive, or highly fractured rock.
Enhanced Hole Deviation Control
The retrac body geometry improves hole straightness, making T51 Retrac Button Bits the preferred choice for tunneling, production drilling, and long-hole blasting.
Optimized Button Layout
With precision-engineered tungsten carbide buttons—spherical or ballistic—T51 Retrac Button Bits deliver fast penetration while maintaining excellent wear resistance.
Superior Wear Resistance
The heat-treated steel body and surface-hardened finish ensure T51 Retrac Button Bits withstand the toughest drilling conditions with minimal bit erosion.
Extended Service Life
Reduced bit wear and lower risk of bit breakage mean fewer replacements, lower operational costs, and higher uptime.
Perfect Fit for T51 Drilling Rods
With robust thread connection and retrac compatibility, these bits maximize energy transfer from the hammer to the rock—boosting drilling efficiency.
Underground mining and tunneling
Bench drilling and production blasting
Slope stabilization and anchor drilling
Hydroelectric and dam foundation works
Quarry operations and civil engineering
