ROC Abrasives Hard Concrete - Diamond Blades 

In the construction sector, diamond cutting is standard practice. Because diamond bits cover the blade's surface, this tool can slice through any kind of construction material. Cuts in concrete are made using diamond blades because a diamond's hardness is unrivaled. When it comes to cutting concrete, only diamond blades can compare to the strength, longevity, and efficiency of concrete. Diamond blades come in a variety of variants specifically designed to cut various concrete materials. It's important to use a diamond-cutting tool designed for the specific kind of concrete you're working with. Finding the correct diamond blades requires research but it is crucial for efficient, risk-free, and precise concrete cutting. 

A diamond blade is an essential tool for any do-it-yourself homeowner with concrete and granite-cutting ambitions. Abrasive blades can make short work of cutting through concrete and granite, but they wear out quickly and may need to be replaced several times over the course of a single job. Although granite is a beautiful and long-lasting stone, it can be difficult to work with due to its hardness. Granite tile is often more cost-effective and convenient to deal with than granite slab, making it a popular choice for kitchen counters. Granite tile outlasts other materials like porcelain, but it's harder to work with due to its density. Granite tiles are too heavy and dense to be scored with a cutting wheel and snapped with a tile cutter. Granite tiles should be cut with a diamond blade.

When it comes to professional cutting applications, selecting the right diamond blade is essential for precision, speed, and durability. The ROC Abrasives: MS15 Not Used But Surface Rust - 14" Hard Concrete, Granite & Paver Diamond Blade - No Label offers exceptional performance for contractors, masons, and construction crews who work with the toughest materials. While this blade may have minor surface rust from storage, its cutting performance remains uncompromised—delivering the strength and sharpness needed for high-demand projects.

We will go over the features, benefits, materials compatibility, and practical tips for getting the most out of this high-quality diamond blade.

What is the ROC Abrasives MS15 Diamond Blade?

The ROC Abrasives MS15 is a 14-inch diamond blade designed for cutting hard concrete, granite, and pavers with ease and precision. Known for its industrial-grade diamond segments and durable steel core, this blade is built to withstand the intense friction, heat, and impact associated with cutting dense, abrasive materials.

While this particular unit is listed as "Not Used But Surface Rust", the rust is purely cosmetic, caused by storage conditions, and does not affect the structural integrity or cutting performance of the blade. Once mounted on a saw, the rust will naturally wear away during use.

Key Specifications

• Brand: ROC Abrasives

• Model: MS15

• Blade Diameter: 14 inches

• Segment Type: Industrial diamond segments for maximum cutting efficiency

• Applications: Hard concrete, granite, pavers, masonry blocks, stone

• Label: No label included

Why Surface Rust Isn’t a Problem

Many contractors hesitate when they see the term surface rust, but in the case of the ROC Abrasives MS15, it’s purely cosmetic. Surface rust:

• Forms on exposed steel when stored in humid environments

• Does not penetrate deep enough to weaken the steel core

• Wears off naturally after the first few cuts

This means you still get the full life expectancy and high performance you’d expect from a brand-new blade—at a reduced cost.

Cutting Capabilities

The ROC Abrasives MS15 is engineered to handle some of the toughest materials in construction. Its cutting versatility includes:

1. Hard Concrete

• Cuts through high PSI, reinforced, and cured concrete

• Maintains a clean, precise edge without excessive chipping

2. Granite

• Designed to handle dense, brittle granite without cracking

• Ideal for countertop fabrication, stone slabs, and outdoor stonework

3. Pavers

• Smoothly cuts through interlocking pavers for landscaping and masonry projects

• Reduces dust when paired with wet cutting equipment

Benefits of the ROC Abrasives MS15 Diamond Blade

1. Professional-Grade Durability

Built for commercial use, the MS15 blade’s diamond segments are laser-welded to ensure maximum heat resistance and bond strength.

2. Cost Savings on a Like-New Blade

Since this unit is unused but has minor surface rust, buyers can save significantly without sacrificing performance.

3. Versatility Across Applications

From cutting hard concrete slabs to granite countertops and paver walkways, the blade is versatile enough for multiple project types.

4. Reduced Vibration

The steel core design helps minimize vibration during operation, leading to cleaner cuts and less operator fatigue.

5. Wet or Dry Cutting Options

While wet cutting is recommended for longer blade life and dust reduction, the MS15 can also be used for dry cutting in certain applications.

Best Practices for Using the ROC Abrasives MS15

To get the longest lifespan and best results from your 14" diamond blade, follow these tips:

1. Proper Mounting

• Ensure the blade is installed on the correct arbor size for your saw

• Confirm directional arrows on the blade match your saw’s rotation

2. Initial Cuts

• When using a blade with surface rust, allow the first few cuts to “dress” the blade and remove oxidation

3. Cutting Technique

• Maintain steady, even pressure—do not force the blade

• Avoid twisting or binding during the cut

4. Cooling the Blade

• Use water when possible to keep the blade cool and reduce dust

• If dry cutting, allow the blade to cool between passes

5. Storage

• Store in a dry, climate-controlled environment to prevent future rust formation
