ST68 Retrac Button Bits

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.

As a China retrac button bit supplier, we can provide you with high-quality button bit includes retrac rock drill bits, such as R25 retract button bit, R28 retract button bit, R32 retrac button bit, R35 retrac button bit, R38 retrac button bit, T38 retract drill bit, T45 retract drill bit, T51 retract drill bit, GT60 retract button bit, ST58 retrac button bit, ST68 retrac button bit, SR35 retrac drill bit...

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:

Mining retrac button bits are equipped with hard and durable buttons made from materials like tungsten carbide. The button configuration, including the number, size, and arrangement of buttons, is carefully designed for efficient rock penetration and breaking in various mining 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.

Drilling Application:

These button bits are specifically designed for mining applications, including surface mining and underground mining. They are suitable for drilling blast holes, production drilling, and exploration drilling in a range of rock formations, from medium to hard.
