Scenarios for using thread button drill bits, cross drill bits, and slotted drill bits

01-06-2025

thread button drill bits Applicable rock types

thread button drill bits are mainly used for medium-hard to hard rocks, such as granite, basalt, etc. These rocks are hard, and ordinary drill bits are easily worn during drilling. The carbide balls of thread button drill bits can effectively crush rocks. For example, in mining, when encountering ores with a hardness of 6-8 on the Mohs hardness, the crushing effect of thread button drill bits is more obvious.

Working environment characteristics:

It is suitable for rotary impact drilling equipment and is widely used in mining and drilling operations in open-pit mines or underground mines. On the excavation working face of underground mines, the space is relatively narrow, and the ball-tooth drill bit can work stably under complex geological conditions with its good wear resistance and impact toughness. Moreover, it can withstand high axial pressure and torque, and is suitable for use under high-load drilling conditions.

Specific application areas:

In oil and gas exploration, for drilling deep hard formations, thread button drill bits can help drill high-quality well-bores. In building foundation engineering, when it is necessary to drill and cast pile foundations on hard rock foundations, thread button drill bits are also a good choice. For example, in the construction of foundation pile holes for large bridges, thread button drill bits can effectively penetrate the rock layer and ensure the quality of the pile holes.

Cross drill bits:

Applicable rock types: Cross drill bits are generally used for softer to medium-hard rocks, such as shale and sandstone. Its cross-shaped blade design enables the drill bit to effectively cut into the rock during rotary drilling. For shale, a rock with a certain stratification structure, the cross drill bit can cut along the stratification direction to reduce drilling resistance. For example, in some small stone quarries, when sandstone with a Mohs hardness of 4-6 is mined for building materials, the cross drill bit can perform better drilling performance.

Working environment characteristics:

The cross drill bit is more suitable for use in a relatively stable working environment, and the impact performance requirements of the equipment are not particularly high. It is mainly used in handheld pneumatic drills or small drilling rigs. In some small road construction projects in mountainous areas, it is necessary to drill holes in mountain rocks for blasting operations. The cross drill bit can be operated by a small handheld pneumatic drill to flexibly drill holes on the rock surface.

Specific application areas: In coal mining, it is used to drill holes in soft or medium-hard rocks on the top and bottom plates of coal seams. For example, when arranging anchor support, the cross drill bit can drill holes for installing anchors. In some ancient building restoration projects, when it is necessary to drill local holes in stone buildings for reinforcement, the cross drill bit can also play its small and flexible characteristics to drill holes in relatively soft stones.

Slotted drill bit

Applicable rock types: Slotted drill bits are mainly used for soft rocks, such as clay rock, mudstone, etc. Its blade shape is simple, similar to a flat tool, and it can break the rock like cutting when drilling in soft rock. For rocks with lower hardness such as clay rock, the drilling speed of the slotted drill bit is relatively fast. For example, in some ceramic raw material mining sites, when mining clay rock with Mohs hardness of 1-3, the slotted drill bit can drill efficiently.

Working environment characteristics:

Slotted drill bits are usually used for drilling operations that do not require particularly high precision, and are used on some simple manual drilling tools or small power tools. It has a simple structure and is easy to manufacture and maintain. In the construction of some small water conservancy projects in rural areas, it is necessary to drill holes on the soft river bank slopes to install drainage pipes. The slotted drill bit can perform drilling operations through simple handheld power tools.

Specific application areas: In the field of horticulture, it is used to drill holes in soft soil or soft rock flower beds to plant large trees. In some simple building foundation reinforcement projects, when drilling holes on soft soil foundations and pouring chemical slurry for foundation reinforcement, the slotted drill bit can quickly complete the drilling task.
