Product Brief

The impregnated diamond bits are professional cutting tools containing high-quality synthetic diamond segments bonded to a durable base material. Designed specifically for cutting non-ferrous materials, the matrix layer of the crown features a uniform distribution of crystals embedded in a powdered metal bond. These tools are essential components in the mineral exploration industry.

Fast Penetration Rate
Matrix is specially designed to expose new diamonds to the cutting face as wear occurs.
Cost Efficiency
Manufactured to provide optimum penetration rates and an extended service life.
Customized Design
Diamond size, concentration, and matrix type are optimized based on formation hardness.

Frequently Asked Questions

What are Impregnated Diamond Bits?
They are cutting tools with diamond segments bonded into a metal matrix, primarily used for core drilling in hard and non-ferrous rock formations.
How do I choose the right matrix height?
Our bits come in matrix heights from 6mm to 14mm. Taller matrices generally provide a longer service life in abrasive formations.
Which rock formations are these bits suitable for?
They are ideal for medium-hard to super-hard rocks, ranging from Grade 6 to Grade 12, including Granite, Basalt, and Quartzite.
What is the standard delivery time?
For standard specifications, the delivery time is normally 7 to 12 working days depending on the order volume.
Do you offer a warranty on the drill bits?
Yes, we provide a 6-month warranty covering abnormal scrap issues like steel body cracking or segment loss under proper operation.
Can you customize bits for specific sizes?
Absolutely. We can customize drill bits based on your specific rock formation data or detailed technical drawings.
