Investigation Engineering Diamond Core Drill Bits 4 Inch Diameter

High-Performance Diamond Core Bits for Hard Formation Drilling

Product Introduction

The bit crown of electroplated diamond core bits are electroplated with layers of synthetic diamonds in the electroplated liquid under certain strictly controled conditions. The whole producing process is carried on in a room temperature that can avoid diamond oxidation and degradation.
Electroplated diamond core bits obtain much faster penetration than impregnated diamond core bits in drilling soft to hard, competent formations. It is similar to the impregnated diamond core bit, for drilling different rock formations, the matrix hardness of electroplated diamond core bit could be different, please refer to "Matrix Selection Index".

Technical Specifications 

Key Features & Advantages

1. Superior Diamond Technology

Premium Synthetic Diamonds: High-grade diamond segments ensure maximum cutting efficiency in hard formations.

Optimized Segment Design: Reinforced matrix prevents premature wear and reduces bit balling.

Customizable Grit & Bond Hardness: Adjustable for specific rock types (e.g., coarse grit for fast drilling, fine grit for smooth coring).

2. Robust Construction for Hard Rock

High-Strength Steel Body: Resists bending and deformation under heavy load.

Enhanced Waterways: Efficient coolant flow prevents overheating in deep drilling.

Reinforced Crown Design: Minimizes breakage in fractured or highly abrasive rock.
