T38 Reaming Drill Bits

The T38 reaming drill bits are tools used in the drilling and mining industry. T38 refers to the drill rod/threaded connection size commonly used in drilling operations. The "T" stands for "thread," and the number "38" indicates the diameter and thread pitch.

Reaming drill bits are designed to enlarge previously drilled holes to a specific size. This is often necessary in drilling operations to ensure that the hole meets the required specifications. Reaming is commonly done after initial drilling with a smaller 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.

Cutting Structure:
The cutting structure of the reaming drill bit is designed to efficiently remove material as it enlarges the hole. This may include various cutting elements, such as buttons made of hard materials.
Design for Specific Applications:
T38 reaming drill bits are designed for specific applications, such as exploration drilling, mining, or construction. The design may vary based on the type of rock or material being drilled.

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.

Compatibility:

These drill bits are designed to be compatible with T38 drill rods and drilling systems. It's crucial to use compatible components to ensure effective and safe drilling operations.
