T38 Retrac Button Bits

Button Configuration:

Retrac button bits are equipped with hard and durable buttons, often made of tungsten carbide. These buttons are strategically placed on the face of the bit to facilitate efficient rock penetration and breaking.

Retrac Design:

The retractable feature is crucial for the adaptability of the bit in changing rock conditions. When the bit encounters harder rock, the buttons retract to minimize wear, thus extending the overall lifespan of the bit.

Thread Type:

Retrac button bits come with specific thread types, such as R-thread (e.g., R25, R32, R38) or T-thread (e.g., T38, T45). The thread type ensures compatibility with various drilling equipment, including drifter rods and rock drills.

Applications:

Retrac button bits find applications in various drilling operations, including mining, quarrying, tunneling, and construction. They are suitable for drilling blast holes, anchor holes, exploration drill holes, and other rock drilling tasks.

Face Design:

The face design of retrac button bits may include options such as flat face, drop center, concave, or convex designs. The choice of face design depends on specific drilling requirements and the type of rock being encountered.

Sizes and Variations:

Retrac button bits come in various sizes to accommodate different drilling requirements. The selection of the appropriate size depends on factors such as the desired hole diameter and the specific geological conditions of the drilling site.
