Diamond Grinding Wheel JOBIextra X1839 2-row 180 x 22.2 mm

JOBIextra X1839 is a diamond grinding wheel with a two-row segment design, sized 180 x 22.2 mm for use on angle grinders with a 22.2 mm arbor. The disc is designed for material removal and surface shaping on hard substrates; its diamond-coated cutting edges offer wear-resistant grinding and consistent profiling for tasks that require both stock removal and controlled finishing. The wheel is intended for construction, stonework and selected metalworking applications where a balance of cutting speed and durability is required.

Advantages

The two-row segmented layout provides efficient debris clearance and consistent contact with the work surface while reducing clogging. Diamond-coated segments deliver high abrasion resistance and long service life compared with conventional abrasive wheels on hard materials. The 180 mm diameter offers a compromise between cutting depth and maneuverability, and the standard 22.2 mm arbor makes the disc compatible with most angle grinders designed for this mount.

Suitable for

• Shaping and profiling of natural and engineered stone
• Rapid removal of concrete and mortar deposits
• Surface preparation and light edging on masonry
• Deburring and stock removal on hard non-ferrous materials

Key specifications

• Diameter: 180 mm
• Arbor bore: 22.2 mm
• Segment design: two-row (segmented)
• Abrasive type: diamond-coated cutting edges
• Primary use: material removal and surface shaping

How to use

Mount the wheel on an angle grinder with a matching 22.2 mm arbor according to the grinder manufacturer's instructions and secure the guard. Begin work at low to moderate speed to establish a controlled cutting action, then adjust pressure and feed rate to maintain consistent contact without forcing the wheel. Use steady, even passes for profiling and stock removal; avoid excessive lateral force that could cause chipping or accelerate wear. Allow the diamond segments to cool periodically by pausing the work or using short, controlled cuts when working continuously.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection, gloves, hearing protection and respiratory protection when cutting or grinding dusty materials. Use the correct grinder speed for the wheel and the material, ensure the workpiece is secure, and follow safe operating practices to maximize wheel life and maintain predictable results.
