T60 Retrac Button Bits

T60 Retrac Button Bits are specialized drilling tools designed for use in percussive drilling methods, particularly in mining and construction applications. The "T60" designation indicates a specific thread type used in the drilling industry. T60 refers to the thread size and configuration used for connecting the drill bit to the drill string.

Retrac Design:

The term "Retrac" in T60 Retrac Button Bits implies a retractable bit design. Retrac bits are characterized by a retractable button that helps protect the bit's carbide buttons (inserts) during non-drilling periods, reducing wear and increasing the bit's lifespan.

Button Bits:

T60 Retrac Button Bits are equipped with carbide buttons on the bit's face. These buttons are the cutting elements and provide the necessary hardness and wear resistance for effective drilling in hard rock formations.

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.

Material Composition:

These bits are typically made of high-quality steel to withstand the mechanical forces and vibrations associated with drilling.

Carbide buttons are strategically placed on the bit's face to endure the impact and abrasion encountered during drilling.

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.

Drilling Method:

T60 Retrac Button Bits are used with top hammer drills, where the drill string is impacted from above, transferring energy to the bit to break and crush the rock.

Thread Retention Mechanism:

The T60 Retrac Button Bits use a specific thread design for secure connection to the drill string. The thread retention mechanism ensures a reliable and stable connection during drilling operations.
