T45 Reaming Drill Bits

T45 reaming drill bits are tools used in drilling and mining operations, similar to T38 reaming drill bits. The "T45" designation refers to the thread size of the drill rod and the connection size, specifically in terms of diameter and thread pitch. The "T" indicates "thread," and the number "45" represents the size of the drill rod.

Thread Size (T45): The T45 thread size is an important specification, ensuring compatibility with drilling equipment that uses this specific thread configuration.

Product Details

Material: These drill bits are typically made from durable materials such as tungsten carbide or other hard alloys to withstand the abrasive conditions encountered in drilling through rocks and other tough materials.
Cutting Structure: The cutting structure of T45 reaming drill bits is designed to efficiently remove material as the drill bit enlarges previously drilled holes. This may involve hard cutting elements such as buttons or inserts.

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.

Application-Specific Design: T45 reaming drill bits are designed for specific applications, and their design may be optimized for different drilling conditions, rock types, and drilling depths.
Compatibility: Like T38 reaming drill bits, T45 bits are designed to be compatible with T45 drill rods and drilling systems. Ensuring compatibility between components is crucial for safe and effective drilling operations.

About US

T45 Reaming Drill Bits

Packing

Size Range: Reaming drill bits come in various sizes to accommodate different hole diameters. The choice of bit size depends on the specific drilling requirements of the project.
Drilling Depth: T45 reaming drill bits are suitable for drilling to various depths, and the choice of bit may depend on the intended depth of the hole.

When using T45 reaming drill bits, it's important to follow manufacturer recommendations for proper use and maintenance. Additionally, considering factors such as the hardness of the rock, drilling conditions, and the specific requirements of the project is essential for achieving optimal drilling performance. Regular inspection and maintenance of the drill bits and associated equipment are also crucial for ensuring safety and extending the life of the drilling tools.
