330mmx25mm 600 Grit Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials

Overview: The 330mmx25mm 600Grit Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials is a precision fine abrasive belt engineered for 1-inch portable belt sanders, bench contour grinders, and precision finishing machines. Featuring electroplated fine 600-grit diamond particles securely bonded to a high-flexibility cloth backing, it delivers smooth scratch-free pre-polishing, prepares edges and radiuses, and produces a uniform semi-gloss luster on hard, brittle materials.

Key Features

• 600 Grit Fine Diamond Layer: Delivers refined pre-polishing and consistent semi-gloss finishes across hard workpieces.
• Wide 25mm Width & 330mm Belt Loop: Perfectly fits 330mm×25mm (13" × 1") mini belt grinders and contour finishing attachments.
• Flexible Tear-Resistant Cloth Backing: Flexes smoothly over small pulleys and intricate contours without creasing or delaminating.
• Heavy-Duty Precision Splice: Bi-directional smooth splice ensures continuous tracking stability and vibration-free running at high belt speeds.

Applications

• Lapidary pre-polishing on gemstone cabochons, fine jade carvings, and intaglios
• Precision glass edge smoothing, bevelling, and internal cutout finishing
• Fine finishing and deburring of tungsten carbide dies, ceramic guides, and hardened alloys
• Smooth blending on technical ceramics, porcelain, and quartz components

Operating Guidelines

• Coolant: Wet operation with continuous water mist or coolant is strongly recommended to prolong belt life and minimize grinding heat.
• Tracking: Adjust belt tension properly to prevent slipping on contact wheels.
• Recommended Speed: 3,000 to 5,500 SFPM for high cutting rates and smooth surface finishes.
