R32 Retrac Button Bits

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.

Retrac button bits are specialized drill bits designed for rock drilling in challenging geological conditions. The term "retrac" indicates a design feature where the cutting buttons (hard, durable inserts) on the drill bit are retractable, allowing them to move inward into the bit body. This feature is particularly advantageous in scenarios where the hardness of the rock formation varies during drilling, helping to protect the buttons from excessive wear.

Product Details

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), to ensure compatibility with the drilling equipment, such as drifter rods and rock drills.

Applications:

Retrac button bits are commonly used in various applications, 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	Application
	Flat face button drill bits are suitable for all rock conditions, especially for the rock with higher hardness and higher abrasiveness. Such as granite and basalt
	Convex Face button bits are designed for fast penetration rates in softer rock.
	Drop center button drill bits are mainly suitable for the rock with low hardness, low abrasiveness, and good integrity. The bits can drill straighter holes.
	Normal Skirt For drilling in very hard and abrasive rock formations.
	Retract Skirt For drilling in loose,broken or fissured rock where it is difficult to retract the drill string due to the hole collapse.

Face Design:

The face design of a retrac button bit may vary and includes options such as flat face, drop center, concave, or convex designs. The choice of face design depends on the 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.

Button Shape
	R：Round Utility carbide shape. Stong configuration against carbide fracture.
	B:Ballistic Higher penetrating carbide shape than Semi ballistic shape. Recommended for soft rock.
	BB：Semi Ballistic Combined wear resistance and high penetration rate. Recommended for medium-hard rock with moderate abrasitivity.
	SA:Spike Highest penetrating carbide shape. Weak configuration against carbide fracture. Recommended for soft to medium-hard work.
