• General workshop metal fabrication tasks

When it may not be suitable

This disc is specifically formulated for steel and metalworking applications. It is not suitable for grinding soft materials like wood, plastic, or non-ferrous metals that may clog the abrasive surface. Additionally, it should not be used on equipment that exceeds the maximum rated speed of 4500 rpm.

Key specifications

• Diameter: 150 mm
• Thickness: 20 mm
• Bore size: 12.7 mm
• Material: Ceramics
• Maximum speed: 4500 rpm

How to use

Before mounting the disc, ensure that your bench grinder is disconnected from the power source. Inspect the disc for any signs of damage or cracks. Secure the disc onto the spindle using the appropriate flanges, ensuring it is centered and tightened firmly but not excessively. Once mounted, perform a test run by letting the grinder spin at full speed for at least one minute while standing clear of the rotation path. Always wear appropriate personal protective equipment, including safety goggles and gloves, during operation.

What to consider before purchase

• Verify that your bench grinder spindle diameter matches the 12.7 mm bore size.
• Ensure your grinder's operational speed does not exceed 4500 rpm.
• Confirm the disc dimensions fit within your grinder's safety guard.

Usage recommendations

Always maintain a steady, light pressure when grinding to prevent overheating the workpiece. Regularly dress the grinding wheel to keep the abrasive surface clean and effective.
