Abrasive Roll with Cloth Backing Alexander KL381J 200 mm grit 80

The Alexander KL381J abrasive roll with cloth backing is a 200 mm wide sanding roll with grit 80 designed for medium-coarse material removal on wood, metal and composite surfaces. Its flexible cloth backing increases tear resistance and durability compared with paper-backed abrasives, making it suitable for continuous use on wide belt sanders as well as for flap wheels and manual sanding tasks. The roll format allows long continuous lengths for industrial and workshop applications where frequent disc changes are impractical.

Advantages

The cloth backing offers improved flexibility and dimensional stability under tension, reducing the risk of tearing during aggressive sanding. Grit 80 provides efficient stock removal while still producing a surface that is ready for subsequent finer sanding steps. The 200 mm width matches common wide-belt and platen sanding equipment and enables consistent contact across larger workpieces. The roll construction provides economy and reduces downtime by allowing long runs without replacing multiple sheets.

Suitable for

• Sanding and leveling wooden boards, panels and furniture components
• Removing rust, scale or paint from metal surfaces before finishing
• Shaping and preparing composite and fiberglass parts
• Use on wide belt sanders, flap wheels and for manual sanding where a cloth-backed roll is preferred

When it may not be suitable

This grit 80 cloth-backed roll is intended for medium-coarse sanding and substantial material removal; it is not appropriate when a fine, scratch-free finish is required as a final step. For extremely hard or precision-ground surfaces where minimal abrasion is needed, a finer grit or a different abrasive type should be selected. The 200 mm width may be larger than required for small, detailed handwork.

Key specifications

• Backing type: cloth (flexible, tear-resistant)
• Grit size: 80 (medium-coarse)
• Working width: 200 mm
• Typical applications: wood, metal, composite materials
• Format: roll providing continuous length for prolonged use

How to use

Cut the required length from the roll and secure it on the sanding machine or mandrel according to the equipment manufacturer’s instructions. Use appropriate feed rates and pressure for grit 80 to avoid excessive loading or heat build-up; for metalwork, use coolant or intermittent passes if needed. Check the cloth backing and abrasive surface regularly for wear and replace sections when the abrasive becomes glazed or torn. Wear recommended personal protective equipment for dust and debris during sanding operations.

What to consider before purchase

• Confirm that a 200 mm working width is compatible with your sanding equipment or intended manual use
• Ensure grit 80 is suitable for the level of material removal and surface finish you require
• Verify whether a cloth-backed roll is preferable to paper-backed options for your application

Usage recommendations

For consistent results, start with medium feed and pressure on your sanding machine and increase gradually if higher stock removal is required. For wood, follow with finer grits to achieve the desired surface quality; for metal, remove debris regularly to avoid loading and check edges for uniform abrasion.
