GRAFF 9 Inch Diamond Blade for Angle Grinder
The GRAFF 9″ Diamond Blade for Angle Grinder is designed for domestic DIY use and versatile cutting across stone, marble, granite, brick, masonry, paving flag, concrete, and kerb. It supports both dry and wet cutting, enabling flexibility in different work environments. The blade heats more slowly during operation, which can extend operating time and reduce downtime. It is built to self-sharpen as the diamond grits erode, with the expectation that two to three cuts on silicon or abrasive stone will restore sharpness. This makes it suitable for ongoing projects where blade longevity matters.
Makita E-02515 9″ Diamond Blade, Segmented
Makita’s E-02515 9″ Diamond Blade features taller 13mm segments designed for longer life and faster cutting. Marketed for cutting concrete, block, brick, pavers, and roof tiles, this blade emphasizes extended life—up to four times longer than some competitors—while maintaining robust cutting performance across common masonry materials. Its segment geometry aims to provide efficient material removal with minimal resistance, supporting faster completion of cutting tasks on larger projects.
FEWELL 9 Inch Diamond Blade, Segmented General Purpose
FEWELL’s segmented 9″ blade is designed for general purpose concrete cutting and masonry work, including concrete, brick, block, and stone. It can be used in both dry and wet conditions and fits most table saws and handheld angle grinders with a 7/8″ arbor. The blade is engineered to deliver a balance of speed and durability, with segmented teeth intended to optimize cutting performance and extend blade life. It is framed as offering solid performance for multi-material projects.
GRAFF 9 Inch Diamond Blade Arbor 7/8″-5/8″
This GRAFF blade is designed for domestic and DIY use, capable of handling stone, marble, granite, brick, masonry, and concrete. It supports both dry and wet cutting. The design emphasizes slow heating for improved performance and features diamond-encrusted segments to enhance cutting efficiency. The blade’s segment spacing is configured to promote faster material removal and reduce project times, making it a practical option for mixed-material jobs.
CRALY 9 Inch Super Thin Diamond Blade
CRALY’s 9 inch blade features a slim 1.8 mm thickness with a 7/8″ arbor, offering a high-speed cutting experience for masonry materials. The 8 mm segment height and 6,500 RPM rating support efficient, deep cuts in concrete, brick, granite, and block. The ultra-thin design reduces kerf, improves precision, and can be suitable for professional or DIY use when sharp, clean cuts are required.

The pack format makes it convenient for ongoing projects or multiple tools sharing a blade type, reducing the need for frequent replacements.
DT-DIATOOL 9 Inch Diamond Turbo Blade
The DT-DIATOOL Turbo Blade is a 9-inch option with a slant-protected design intended for deep and efficient cutting of granite, marble, concrete, and other hard stones. The segment height and segment design aim to maximize material removal while maintaining control during deep cuts. It is compatible with 5/8-11 thread grinders and is described as multi-purpose for cutting and grinding tasks.
Buying Guide
When selecting a 9 inch diamond blade for an angle grinder, consider these factors:
- Material compatibility: Choose blades optimized for concrete, stone, brick, or general masonry as needed. Segmented teeth excel in masonry and hard materials, while turbo designs can improve deep-cut performance.
- Arbor size: Confirm the arbor fits your grinder (7/8″, 5/8″, etc.). Some blades fit multiple arbors with adapters; others require exact matches.
- Thick vs. thin profiles: Thinner blades reduce kerf and may offer cleaner cuts, but can be more fragile. Thicker blades offer durability for heavy-duty use.
- Dry vs. wet cutting: Some blades are designed for both dry and wet use. Wet cutting helps reduce dust and temps but requires a water source.
- Segment height and number of segments: Higher segment height can enable faster cutting and longer life on heavy materials, while more segments can improve heat dissipation and dust control.
- Cutting speed vs. blade life: Longer blade life often comes at some expense to peak cutting speed; match your project scale and cadence to the blade’s strengths.
- Maintenance: Some blades self-sharpen as they wear; others may require replacement or reconditioning after a set of cuts.
- Project type: For DIY home projects, blades marketed for universal or general purpose use often provide balanced performance. For professional jobs with granite or hard stone, turbo or thicker segmented blades may be preferable.
Always follow manufacturer safety guidelines, wear protective gear, and ensure proper mounting and grinder compatibility before use. Consider having spare blades on hand for long projects to minimize downtime and maintain consistent cutting performance.
