Thin-walled Impregnated Diamond Drill Bit

Product Details

Thin-walled impregnated diamond drill bits are efficient drilling tools used in modern construction, installation, municipal construction, and other fields. These drill bits exhibit broad adaptability to hard and brittle materials such as reinforced concrete, building stones, glass, and ceramics. They are primarily used for drilling installation holes for water, electricity, gas, and sanitary pipelines on building components, as well as for engineering sampling drilling. They can also be used for drilling various hard and brittle material products. Drilling with thin-walled impregnated diamond drill bits offers advantages such as regular and smooth hole openings, high efficiency, low labor intensity, and the ability to ensure project quality.

Technical Specifications

Height of Impregnated Layer

  As shown in the schematic diagram, the height of the impregnated layer refers to the height of the matrix part of the drill bit head that contains the diamond working layer.
We can offer a range of drill bits with varying height of the impregnated layer, spanning from 9mm to 20mm. Additionally, if customers have specific requirements, we can tailor-make the height of the impregnated layer according to their needs. Unless otherwise stated, the standard height of the impregnated layer for our drill bits is 12mm.

Drill Bit Nozzle Shape

Based on different rock formations and drilling conditions, we produce synthetic diamond impregnated drill bits with various lip shapes.

Standard Nozzle

■ Standard design ■ Suitable for a wide range of strata

Fan-Shaped Nozzle

■ It has significantly increased the water flow volume ■ The cutting speed has been improved ■ Suitable for fractured rocks and highly abrasive formations

Main and Secondary Gates

■ Suitable for high-speed cutting and drilling to increase the pressure on the working surface ■ Suitable for hard formations

Bottom Spray Circular Water Nozzle

■ This design reduces the scouring effect of water flow on the rock core, thereby enhancing the core recovery rate ■ Suitable for fractured or granular rock formations

Bottom Spraying Waist-Shaped Water Nozzle

■ Suitable for fragmented sedimentary or deformed strata ■ The water hole in a waist shape has better water flow efficiency than the circular one, and it can more effectively prevent water blockage and drill burning

Deep Trough

■ This design combines the advantages of a standard lip surface and a bottom-spray lip surface, featuring a simple and reliable process ■ Suitable for broken or hard formations

Spiral Water Outlet

■ Improve work efficiency by reducing the interaction time between the hole and the core ■ Suitable for softer to medium-hard formations
