Vacuum Brazed or Vitrified Diamond Grinding Discs — Which Performs Better?

 When choosing a diamond grinding disc, performance isn’t just about cutting speed. Bonding technology plays a critical role in material removal rate, surface finish, heat control, and tool life.

🔹 Vacuum brazed diamond discs deliver extremely aggressive cutting thanks to fully exposed diamonds—ideal for rapid stock removal, deburring, and rough grinding.

🔹 Vitrified diamond discs provide superior precision, thermal stability, and surface finish through controlled, self-sharpening abrasive exposure.

Diamond grinding discs


👉 Speed vs. precision. Productivity vs. consistency.
The right choice depends on your application.

At JDR Diamond Tools, we help customers match the right diamond bond to the right grinding challenge.

💬 Which disc type do you rely on most—and why?

✅ 4. Application-Specific Recommendations (By Industry)

Turbo Diamond Blades vs. Continuous Rim Blades: What’s the Difference?

Image
  When it comes to cutting tools, choosing the right blade for your project can make all the difference. Turbo diamond blades and continuous rim diamond blades are two popular choices, each with distinct characteristics that make them ideal for specific applications. Let’s explore the key differences between these two types of blades to help you make an informed decision. 1. Rim Design Turbo Diamond Blades : Feature a serrated rim with a wavy or “turbo” pattern. The serrations enhance airflow and cooling, reducing friction during cutting. Designed to balance speed and precision, making them versatile for various tasks. Continuous Rim Blades : Have a smooth, unbroken rim that ensures a steady, uninterrupted cutting action. Ideal for achieving clean, precise cuts with minimal chipping. Often used for projects where edge quality is critical. 2. Cutting Applications Turbo Diamond Blades : Best suited for harder materials such as granite, concrete, and brick. Ideal for projects requirin...

Transforming Challenges into Solutions: Vacuum Brazed Discs for Refractory Bricks

Image
cutting tools for refractory bricks In the construction and engineering industries, challenges are inevitable. Whether it's cutting through tough materials like refractory bricks or meeting tight project deadlines, professionals need reliable tools to turn these challenges into solutions. Vacuum brazed diamond cutting discs are one such tool, designed to tackle the toughest tasks with precision and efficiency. The Challenge: Cutting Refractory Bricks Refractory bricks are critical in high-temperature applications, but their hardness and density make them notoriously difficult to cut. Traditional cutting tools often fail to deliver the clean, precise cuts needed, leading to material waste, tool damage, and increased project timelines. This is where vacuum brazed diamond discs shine. The Solution: Vacuum Brazed Diamond Cutting Discs Vacuum brazing is a process that bonds diamond particles to a cutting disc using a vacuum furnace. This technique creates a strong bond, ensuring that th...
