DB1824 Diamond Spherical Compound Teeth

It consists of a polycrystalline diamond layer and a cemented carbide matrix layer. The upper end is hemispherical and the lower end is a cylindrical button. When impacting, it can well disperse the impact concentration load at the apex and provide a large contact area with the formation. It achieves high impact resistance and excellent grinding performance at the same time. It is a diamond composite tooth for mining and engineering. The diamond spherical composite tooth is the best choice for future high-end roller cone bits, down-the-hole drill bits and PDC bits for diameter protection and shock absorption.

DB1824 Diamond Spherical Compound Teeth is a high-performance diamond enhanced compact (DEC) product specifically developed for mining, foundation engineering, and rock drilling applications. It consists of a premium polycrystalline diamond layer and a high-strength tungsten carbide substrate, featuring a hemispherical diamond working surface and cylindrical base structure. This design effectively disperses impact loads while maximizing contact area with the formation, delivering outstanding impact resistance, wear resistance, and crushing efficiency.Play

Applicable Strata

DB1824 is engineered to perform efficiently in:

  •  Medium-hard to hard rock formations
  • Abrasive sandstone
  • Limestone formations
  • Granite and basalt formations
  • Coal mining environments
  • Quarrying and tunneling projects
  • Foundation and geothermal drilling applications

Its spherical profile provides superior load distribution, making it especially effective in highly fractured and impact-intensive formations.

Core Product Advantages

Exceptional Compressive Strength

The reinforced carbide substrate and optimized diamond layer enable DB1824 to withstand extremely high compressive loads encountered during aggressive drilling operations.

Superior Impact Resistance

The hemispherical geometry disperses concentrated impact forces across a larger area, significantly reducing localized stress and minimizing cutter failure.

Outstanding Wear Resistance

The high-quality polycrystalline diamond layer delivers excellent abrasion resistance, ensuring long service life even in highly abrasive formations.

Excellent High-Temperature Stability

Advanced sintering technology provides stable performance under elevated drilling temperatures, reducing thermal degradation during extended operations.

Enhanced Drilling Efficiency

The dome-shaped cutting structure promotes efficient rock crushing and energy transfer, improving penetration rates while reducing operational costs.

Extended Bit Service Life

By combining impact resistance and wear resistance, DB1824 helps extend the overall lifespan of drilling tools, reducing downtime and replacement frequency.

Precise Size Specifications

DB1824 is manufactured with a diameter of 18.0 mm and an overall height of 24.0 mm. The spherical dome features a radius of 9.24 mm and an exposed working height of 7.1 mm, providing an ideal balance between penetration capability, impact absorption, and wear life. This dimensional configuration makes DB1824 suitable for heavy-duty mining bits, roller cone bits, DTH hammers, and specialized drilling tools.
