Features of ROC Abrasives - Diamond Blades 

Only ROC uses Hydro-Forging Technologies, making them unique among diamond tool manufacturers (HFT). In HFT, we use electrohydraulic forming. This technique for shaping metal involves employing an electric arc discharge in a liquid to transform electrical energy into mechanical energy. When making new segments and joining them together with lasers, we rely on Hydro-Forging Technologies, the cutting-edge technology at the time. Through the use of HFT, our diamond tools are able to outperform comparable premium diamond blades on the market by as much as 50% in speed and 50% in the smoothness of cut.

Master Your Cutting Projects with the ROC Abrasives: GB15 - Green Concrete & Asphalt Diamond Blade

When it comes to tackling tough materials like green concrete and asphalt, contractors and professionals know that having the right diamond blade can mean the difference between a job well done and a costly setback. That’s where the ROC Abrasives: GB15 - Green Concrete & Asphalt Diamond Blade steps in as a game-changer.

Whether you’re working on road repairs, sidewalks, driveways, or large commercial projects, this blade is built to handle the challenges of abrasive materials, delivering durability, speed, and precision every time.

In this comprehensive guide, we’ll explore what makes the ROC Abrasives: GB15 blade stand out, why it’s ideal for green concrete and asphalt, and how using the right diamond blade can boost your productivity and finish quality.

What is the ROC Abrasives: GB15 - Green Concrete & Asphalt Diamond Blade?

The ROC Abrasives: GB15 is a premium segmented diamond blade engineered specifically for cutting:

• Green (fresh) concrete

• Asphalt

• Other highly abrasive materials

Designed with high-quality diamond segments and an optimized bond, this blade keeps cutting sharp and clean even in some of the most challenging conditions.

Key points that define the ROC Abrasives: GB15 blade:
✅ Optimized for early-entry and green concrete cutting
✅ Ideal for asphalt and abrasive surfaces
✅ Long-lasting performance due to premium bond technology
✅ Fast, precise cuts with reduced blade wear

Why Cutting Green Concrete and Asphalt Is Different

Before concrete fully cures, it’s softer and more abrasive, which can quickly wear down standard blades. Asphalt, by nature, is also highly abrasive and can chew through lower-quality diamond blades in no time.

That’s why blades like the ROC Abrasives: GB15 - Green Concrete & Asphalt Diamond Blade are engineered with:

• Soft bond formulas to release diamond grit steadily

• Special segment design to prevent undercutting

• High diamond concentration for durability

The result? Contractors can cut green concrete shortly after it’s poured and score precise joints in asphalt — all while preserving blade life.

Features That Make the GB15 Blade Stand Out

1. Premium Diamond Segments
ROC Abrasives packs the GB15 blade with high-quality diamonds, ensuring it stays sharp through repeated cuts on abrasive materials.

2. Designed for High Abrasion
Its specialized bond is softer than traditional blades, allowing fresh diamond grit to be exposed quickly, maintaining cutting speed.

3. Segmented Design
The classic segmented rim not only helps with cooling but also ejects slurry and dust efficiently — critical when cutting asphalt and green concrete.

4. Versatility
Ideal for a range of tools, including walk-behind saws and hand-held saws, making it suitable for different job site applications.

Applications: Where You’ll Use the ROC Abrasives: GB15 Blade

The GB15 blade is designed for professionals who need to cut:

• Freshly poured concrete slabs (green concrete)

• Asphalt repair patches and overlays

• Expansion joints and control joints

• Pavements, sidewalks, and parking lots

• Driveways and road resurfacing projects

Because of its ability to handle high-abrasion materials, it’s a favorite among:
✅ Road construction crews
✅ Concrete contractors
✅ Utility workers
✅ Municipal teams handling infrastructure repairs

Early Entry Cutting and the GB15 Blade

One of the blade’s most valuable advantages is supporting early-entry cutting:

• Control joints can be cut 1–2 hours after finishing, reducing random cracking.

• Helps guide natural concrete shrinkage where you want it.

• Saves contractors time and money by speeding up project timelines.

This makes the ROC Abrasives: GB15 not just a tool, but a strategic advantage on busy job sites.
