T45 Retrac Button Bits

The Retrac Bits are widely applicable to mining industry, tunneling and underground engineering, open pit, construction drill,blast industry, civil engineering operations,road, gas line, pipe and trench projects,quarry work, rock anchoring and ground stabilization projects, water well industry, etc,

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.

Button Configuration:

Retrac button bits are equipped with tungsten carbide buttons strategically placed on the bit's face. These buttons are designed for effective rock penetration and breaking. The retractable feature allows the buttons to adapt to changing rock hardness, improving their lifespan.

Retrac Design:

The retractable design is a crucial feature. When the bit encounters harder rock, the buttons retract, reducing contact and wear. This design contributes to increased longevity, especially in applications where the drilling environment may have varying rock formations.

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.

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), ensuring compatibility with various drilling equipment like drifter rods and rock drills.

Applications:

These bits are commonly used in applications such as 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 are available 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.

Maintenance:

Regular inspection and maintenance are essential for optimal performance. Monitoring the condition of the cutting buttons and replacing them when worn are routine practices to maximize the lifespan of the retrac button bit.
