TSP Diamond Core Bits Wear Resistant For Mineral Exploration Rock Coring

TSP Core Bit

The TSP Core Bit, also known as a Thermally Stable Polycrystalline Diamond Core Bit, is designed for geological core drilling, mineral exploration, geotechnical investigation and rock sampling.

Thermally stable polycrystalline diamond cutters are positioned around the bit crown. During rotary drilling, the exposed cutting elements cut and shear the rock while the waterways carry drilling fluid across the bit face to cool the crown and remove cuttings.

Compared with conventional carbide cutting elements, TSP diamond cutters provide high hardness, wear resistance and improved thermal stability. TSP core bits can be configured for massive, broken or abrasive formations, although the final bit selection should always be based on actual rock properties and drilling parameters.

Brighttop Global Co., Ltd. can supply TSP core bits in different sizes, cutter arrangements, crown profiles and waterway configurations. Customized designs are also available for specific core barrel systems and drilling conditions.

Key Features

• Thermally stable polycrystalline diamond cutting elements

Main Applications

• Mineral exploration drilling
• Geological core sampling
• Mining prospecting
• Geotechnical site investigation
• Rock formation analysis
• Coalfield exploration
• Engineering geological investigation
• Surface exploration drilling
• Underground exploration drilling
• Construction and foundation investigation
• Environmental and hydrological investigation

Suitable Formation Conditions

TSP core bits may be considered for:

• Massive rock formations
• Broken or fractured formations
• Abrasive formations
• Soft-to-hard formations when correctly configured
• Medium-hard abrasive rock
• Formations requiring durable exposed cutters

Because formation descriptions vary between projects, it is better to avoid making an absolute statement such as “one bit drills every formation.” Cutter shape, exposure, crown profile, waterway design, rotational speed, bit pressure and flushing conditions all affect actual performance.

FAQ:

What is a TSP Core Bit?

A TSP Core Bit is a geological coring tool equipped with thermally stable polycrystalline diamond cutters mounted in the crown matrix. It is used to cut an annular path in the rock while preserving the center section as a core sample.

What does TSP mean?

TSP stands for Thermally Stable Polycrystalline Diamond. It is a polycrystalline diamond material developed to retain useful cutting and wear properties under elevated-temperature conditions.

What formations are suitable for a TSP Core Bit?

TSP core bits can be configured for massive, broken and abrasive formations. However, actual suitability depends on cutter type, cutter arrangement, crown design, flushing conditions and operating parameters.

What is the difference between a TSP Core Bit and an Impregnated Diamond Core Bit?

A TSP core bit uses individual thermally stable polycrystalline diamond cutting elements mounted in the crown. An impregnated diamond core bit contains smaller diamond particles distributed throughout the matrix, exposing new diamonds as the matrix wears.

Can the TSP Core Bit be customized?

Yes. Sizes, cutter shapes, cutter arrangements, crown profiles, waterways and connections can be customized according to the core barrel system and drilling conditions.

Which information is required for a quotation?

Please provide the bit size, core barrel system, connection, rock formation, drilling depth, quantity and any available drawings or previous drilling records.
