3M 01730 Imperial Hookit 740I 5-Inch 36E Grit Hook & Loop Abrasive Disc

The 3M Imperial Hookit 740I Abrasive Disc (MPN 01730) is a heavy-duty, coarse-grade sanding disc engineered for aggressive auto body repair and metalworking applications. Built on a heavy E-weight paper backing, this 5-inch disc delivers long life and consistent high performance across the toughest jobs.

Key Features:

• Aluminum oxide mineral cuts fast and self-fractures during use, continuously exposing fresh cutting edges to stay sharper longer than standard abrasives
• Resin-bonded grain provides superior heat resistance, extending the working life of each disc
• Heavy E-weight paper backing resists tearing and edge wear during aggressive sanding passes
• Hookit hook-and-loop attachment system enables fast, clean disc changes and allows discs to be reattached and reused for the full extent of their abrasive life
• Open coat construction reduces loading for better performance on paints, fillers, and metals
• 36E coarse grit — ideal for heavy material removal; also available in 40E and 60E grades
• Suitable for use on fiberglass, body filler, metal, and plastic surfaces
• Compatible with hand or power sanding in dry applications

Designed for professional auto body technicians, the 740I disc excels at paint removal, rust removal, metal shaping, filler shaping, and deburring. The brushed nylon loop backing attaches firmly to J-hook disc pads (sold separately). Sold as 25 discs per box, 4 boxes per case. Color: Purple. Country of Origin: United States.
