180mm 7 Inch Metallographic Cutting Discs are precision-engineered abrasive tools specifically designed for metallographic sample preparation. Unlike ordinary cutting wheels, these discs are optimized to cut metallic specimens with minimal deformation, heat-affected zones, or microstructural damage, ensuring accurate results in subsequent microscopic examinations. Manufactured with premium abrasive grains and reinforced resin bond, these cutting discs combine cutting efficiency, durability, and structural stability. Their balanced performance makes them an essential tool for laboratories, research centers, and quality control departments across various industries.

Precautions Before Use Inspect each disc for cracks or damage before use. Replace immediately if defects are found. Confirm that disc dimensions, thickness, and arbor hole match the cutting machine’s specifications. Always disconnect power before installing or removing discs. Mount discs securely with appropriate flanges to ensure balance. Use protective guards, safety goggles, gloves, and face shields. Clamp specimens firmly to avoid shifting during cutting. Apply steady, moderate pressure—avoid forcing the disc. Stop operation if abnormal vibration, noise, or sparks occur and check immediately. Do not exceed the maximum operating speed specified by the manufacturer. Need bulk orders or special specifications?
