T51 Reaming Drill Bits

The T51 reaming drill bit is a special tool designed for reaming operations in rock drilling applications. The designation "T51" specifies the thread type and size of the drill bit, while "reaming" indicates the specific purpose of enlarging an existing hole to obtain a more accurate diameter or improve the finish of the hole.

Thread Type:

The "T" in T51 stands for "trapezoidal," indicating that the thread type has a trapezoidal shape. The "51" denotes the diameter of the thread in millimeters. T51 is a standardized thread type used in the drilling industry to ensure compatibility with various drilling equipment.

Reaming Operation:

Reaming drill bits are specifically designed for the reaming process, where the drill bit is used to enlarge an existing hole. This process is often employed to achieve a more accurate diameter, improve hole straightness, or enhance the surface finish of the hole.

Product Details

Material and Construction:
T51 reaming drill bits are typically constructed from high-strength materials, such as tungsten carbide for the cutting edges. The body of the bit is made from alloy or tool steel to withstand the forces encountered during reaming.
Applications:
Reaming drill bits in mining are used for various purposes, including blast hole drilling, exploration drilling, and production drilling. They contribute to achieving precise hole dimensions and improving hole quality in different rock formations.

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.

Sizes and Variations:
Mining reaming drill bits come in various sizes to accommodate different mining requirements. The selection of the appropriate size depends on factors such as the desired final hole diameter and the specific geological conditions of the mining site.
Compatibility:
It's crucial to ensure that mining reaming drill bits are compatible with the drilling equipment being used. Checking the thread type and other specifications helps ensure safe and efficient drilling operations.
