R38 Retrac Button Bits

Retrac button bits are mainly used in loose rock mass with relatively broken rock. The retrac skirt design can assist in retrieving the drill tool, reduce the phenomenon of bit stuck and buried, and help improve the straightness of the borehole.

Tianyue retrac button bits are made of high-quality steel and cemented carbide as raw materials, so they have a long service life. And the use of retrac bits minimize the loss of impact energy during transmission. In addition, the advanced button fixing technology makes the fixing force uniform and not easy to loose buttons. Meanwhile, the use of retract drill bits also ensures the perpendicularity of the borehole, so that the impact energy is concentrated on the rock and the drilling efficiency is improved.

Product Details

A retrac button bit is a type of drill bit designed for rock drilling applications, especially in challenging and abrasive geological conditions. The term "retrac" refers to a specific design feature where the cutting buttons on the bit are retractable, meaning they can move inward into the bit body. This design is particularly useful in situations where the hardness of the rock formation can vary, allowing the buttons to retract and protect themselves from excessive wear.

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 hard, durable buttons (cutting inserts), usually made of tungsten carbide. The buttons are strategically placed on the bit to ensure efficient rock penetration and breaking.

Retrac Design:

The retractable feature allows the cutting buttons to move inward when encountering hard rock, reducing wear and tear. This design enhances the longevity of the bit and contributes to its performance in varying rock conditions.

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.
