ORIENTCRAFT Ceramic Grinding Disc Stone 150x20x32 mm Grit 60

The ORIENTCRAFT ceramic grinding disc, measuring 150x20x32 mm with a 60 grit, is a high-quality abrasive tool engineered for precision metal grinding and sharpening. Constructed from durable ceramic stone, this disc is designed to withstand rigorous workshop conditions while maintaining consistent material removal rates. It is a reliable choice for professionals and hobbyists who require a steady and effective tool for surface preparation and edge maintenance on various metal components.

Advantages

This grinding disc offers exceptional durability and heat resistance, which are critical for maintaining the integrity of the workpiece during extended grinding sessions. The 60 grit provides an optimal balance between aggressive material removal and a relatively smooth finish, making it versatile for both rough shaping and intermediate sharpening tasks. Its robust ceramic composition ensures a long service life, reducing the frequency of replacements and enhancing overall workshop productivity.

Suitable for

• Sharpening metal tools such as chisels, drill bits, and knives
• Removing burrs and smoothing rough edges on metal parts
• General surface finishing and material removal tasks
• Maintenance of workshop equipment and metal components

When it may not be suitable

This disc is specifically designed for metal grinding and may not be suitable for cutting or grinding non-metallic materials like wood, plastic, or masonry, as these can clog the abrasive surface. It should not be used on high-speed angle grinders that exceed the specified maximum rotational speed.

Key specifications

• Diameter: 150 mm
• Thickness: 20 mm
• Bore size: 32 mm
• Grit: 60
• Material: Ceramic stone
• Maximum rotational speed: 4458 rpm

How to use

Before installation, ensure the bench grinder is disconnected from the power source. Inspect the disc for any visible cracks or damage. Mount the disc onto the spindle, ensuring it fits securely with the appropriate flanges. Tighten the nut firmly but avoid overtightening to prevent cracking the ceramic material. Once mounted, perform a test run by letting the grinder reach full speed for at least one minute while standing clear of the rotation path. Always wear appropriate personal protective equipment, including safety goggles and a dust mask, during operation.

What to consider before purchase

• Verify that your bench grinder spindle diameter matches the 32 mm bore size of the disc
• Ensure your grinder's maximum speed does not exceed the 4458 rpm limit of the disc
• Confirm that the 60 grit is appropriate for your specific sharpening or grinding requirements
• Check the physical space on your grinder to ensure a 150 mm diameter disc fits safely within the guard

Usage recommendations

Always maintain a light, steady pressure when grinding to prevent overheating the metal and to prolong the life of the ceramic disc. Regularly dress the grinding wheel to keep the surface clean and sharp for consistent performance.
