ST58 Reaming Drill Bits

Mining reaming drill bits are specialized tools designed for reaming operations in mining applications. Reaming involves enlarging an existing hole to achieve a more precise diameter or improve the finish of the hole. These drill bits play a crucial role in the drilling process in the mining industry, where accuracy and hole quality are essential. Here are key features and information about mining reaming drill bits:

Design:
Reaming drill bits for mining typically have a robust and durable design to withstand the challenging conditions encountered in mining operations. The cutting structure may vary, but it is engineered to efficiently enlarge holes in various rock formations.
Thread Type:
The thread type of the reaming drill bit is crucial for compatibility with the drilling equipment. Common thread types include R-thread (round threads) and T-thread (trapezoidal threads), depending on the specifications of the drilling rig.

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 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.

Performance in Mining Environments:
Mining reaming drill bits are designed to perform well in the challenging environments of mining operations, where drilling conditions can be abrasive and demanding. Their durability and cutting efficiency are essential for the success of mining projects.
