457mmx18mm Multi-Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 457mm x 18mm Flexible Diamond Sanding Belt (approx. 18" length x 3/4" width) is a precision portable abrasive belt designed for Dynafile-style pneumatic belt sanders, electric contact-arm sanders, and detail grinding tools. Electroplated industrial diamond crystals bonded securely to a flexible, high-tensile waterproof backing provide aggressive stock removal, cool wet or dry cutting, and exceptional durability in tight corners, inside radii, and complex profiles.

Key Features

• Full Range of Grits & Patterns: Available in Dot and Arrow patterns from coarse 60 Grit calibration down to 1800 Grit ultra-fine polishing.
• Versatile Portable Fit: Standard 457mm x 18mm (approx. 18" x 3/4") size fits handheld portable file sanders and detail grinding machines.
• Flexible & Tear-Resistant: Conforms smoothly over small-diameter contact wheels and slack-of-belt areas without cracking or edge fraying.
• Smooth Precision Joint: Low-profile butt splice eliminates vibration and prevents surface chatter marks during precision work.

Applications

• Glass cold-working, arrising cut edges, and bottle bevel leveling
• Lapidary gemstone rough grinding, cabochon smoothing, and intricate carving
• Ceramic edge smoothing, porcelain tile grooving, and composite contour shaping
• Thermal spray coatings, aerospace alloys, and weld seam deburring

Operating Guidelines

• Coolant: Use with continuous water mist or light coolant spray when feasible to prevent diamond thermal wear and clear fine swarf.
• Tension & Tracking: Adjust tool tensioning arm to avoid over-stretching the narrow belt.
• Speed: Recommended surface speed 2,500 to 5,000 SFPM.
