Customizable Metal Sintered Diamond Drill Bits Silver Gray First Class

Product Overview

Metal sintered diamond drill bits are efficient and durable drilling tools, widely used in geological exploration, construction engineering, stone processing and other fields. Its core feature is that the diamond abrasive grains are firmly fixed on the drill bit base through the high-temperature sintering process of metal powders such as cobalt, nickel, copper, etc., which has both high hardness and wear resistance.

Structure and composition

Diamond layer:

The cutting layer is composed of artificial or natural diamond particles, and can be arranged in single or multiple layers according to the purpose. High-grade diamonds such as SMD or MBD series can increase the service life.

Metal matrix:

Cobalt-based, iron-based or copper-based alloys are commonly used as bonding phases, and different rock formations can be adapted by adjusting the metal ratio (such as increasing copper to reduce hardness and increase toughness).

Matrix:

The steel body such as 45# steel provides structural support and is usually combined with the diamond layer by sintering or brazing.

Features and Advantages

1. It is more resistant to high temperatures than resin/electroplating binders, can withstand temperatures above 800°C, and is suitable for high-speed and heavy-load processing.

2. It has strong abrasive holding power, is not easy to fall off, and has a 3-5 times longer lifespan.

Application scenarios

Geological drilling: used for medium-hard to hard strata (6-12 rock formations), such as oil and mineral exploration.

Construction engineering: concrete drilling, reinforced concrete demolition (need to avoid high temperature ablation).

Stone processing: precise hole opening of brittle materials such as marble and tiles.

Sintering process

Hot pressing sintering (HP): temperature 700-1000℃, pressure 30-50MPa, high density.
