230mm Hot Pressed Segmented Diamond Cutting Blade for Concrete & Masonry
R424.35
ROX® Segmented Cutting Blades – Contractor (Hot Pressed) are contractor-grade diamond cutting blades designed for fast cutting and rapid stock removal in concrete, brick, block, roof tile and paving applications.
The segmented rim design provides open spaces between the diamond segments, helping the blade remove material quickly during cutting. This makes segmented diamond blades particularly useful where cutting speed and productivity are more important than achieving a completely chip-free edge.
The Contractor hot-pressed construction is designed to provide longer blade life, faster cutting and lower cost per metre compared with entry-level cold-pressed segmented blades.
The ROX® Contractor segmented blade is available in a 230 mm size and is designed for use with compatible standard angle grinders and joint cutters.
| Code | Description | Size |
|---|---|---|
| 80/2/422 | SEGMENTED CUTTING BLADE | 230 mm |
A segmented diamond blade is a circular cutting blade with diamond-impregnated cutting segments separated by gullets around the outer rim.
The spaces between the segments help the blade remove material rapidly while allowing debris to clear from the cutting area. This design makes segmented diamond blades particularly suited to fast cutting and stock removal in construction materials.
Segmented blades are commonly used for concrete, brick, block, paving materials and other masonry applications where cutting speed is a priority.

What is a segmented diamond blade?
A segmented diamond blade is a diamond cutting blade with separated cutting segments around the rim, designed for rapid cutting and material removal.
What is a segmented diamond blade used for?
Segmented diamond blades are commonly used for cutting concrete, bricks, blocks, roof tiles, paving stones and paving blocks.
Why use a segmented blade for concrete?
Segmented blades are designed for fast cutting and rapid stock removal, making them suitable for concrete and other construction materials where cutting speed is a priority.
What is a hot pressed diamond blade?
Hot pressed refers to the manufacturing process used to form the diamond cutting segments. FloorsHQ positions its Contractor hot-pressed segmented blade as a longer-life, faster-cutting option than its entry-level cold-pressed equivalent.
What size is the ROX® Contractor segmented blade?
The ROX® Contractor hot-pressed segmented cutting blade listed by FloorsHQ is 230 mm in diameter.
Can a segmented diamond blade cut bricks?
Yes. The ROX® Contractor segmented blade is specified for cutting bricks and other masonry materials.
Can a segmented diamond blade cut paving blocks?
Yes. Paving stones and paving blocks are listed among the intended applications for the Contractor segmented blade.
Is a segmented blade better than a continuous blade?
Neither design is universally better. Segmented blades prioritise fast cutting and material removal, while continuous-rim blades are better suited to accurate cutting and smoother, more chip-free edges.
What is the difference between a segmented and turbo diamond blade?
Segmented blades are designed for rapid stock removal, while turbo blades combine characteristics of segmented and continuous designs to provide fast cutting with reduced edge chipping.
Can I use a 230 mm diamond blade on any angle grinder?
No. The blade must be compatible with the machine's permitted blade diameter, arbor specification and maximum operating speed. Always follow the machine and blade manufacturer's requirements.
Who should use Contractor hot-pressed segmented blades?
They are intended for contractors and other users who require a durable blade for repeated cutting of concrete, brick, block and paving materials.
| Feature | Segmented | Turbo | Continuous Rim |
|---|---|---|---|
| Cutting Speed | Fastest | Fast | Slower |
| Stock Removal | Excellent | Excellent | Lower |
| Edge Finish | More chipping | Reduced chipping | Smoother |
| Best For | Concrete & masonry | General-purpose mixed cutting | Precision tile & stone cutting |
| Typical Priority | Speed | Speed + finish | Accuracy + finish |
The best blade depends on whether the job prioritises cutting speed, material removal, edge quality or precision. For rapid cutting of concrete, bricks, blocks and paving materials, a segmented blade is generally the appropriate blade design within this product range.
