3M 7010363499 Hookit 401Q Abrasive Disc 2000 Grit 5 Inch

Product Description

The 3M 7010363499 is a Hookit 401Q coated abrasive disc designed for finish sanding in both wet and dry conditions. It uses a silicon carbide mineral bonded to an A-weight waterproof paper backing, delivering fast cutting action and a refined surface finish. At 2000 grit, it is suited for final-stage finishing work where surface quality is critical. The Hookit attachment system allows for quick disc changes on compatible random orbital and rotary sanders. Automotive refinishers, metal fabricators, and woodworking professionals are the primary users of this disc.

This disc is used across a range of substrates including paint, primer, gel coat, metal, and wood. At 5 inches in diameter and rated for up to 12000 RPM, it fits standard 5-inch Hookit backing plates used in automotive body shops and finishing operations. It performs equally well in hand-sanding blocks designed for wet applications. The waterproof backing resists breakdown during wet sanding, reducing loading and extending disc life compared to standard paper-backed abrasives.

Key Features

• Silicon carbide mineral cuts faster than aluminum oxide and leaves a smoother finish
• A-weight waterproof paper backing supports wet or dry sanding without delaminating
• 2000 grit removes fine scratches and prepares surfaces for polishing or topcoat
• Hookit hook-and-loop attachment allows fast disc swaps without tools
• Rated to 12000 RPM for use with standard pneumatic and electric orbital sanders
• Compatible with paint, primer, gel coat, metal, and wood substrates

Compatibility

Designed for use with 5-inch Hookit hook-and-loop backing plates on random orbital and rotary sanders rated for wet or dry abrasive disc operation.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from its air supply or electrical source. Align the disc flat against the backing plate before pressing to engage the hook-and-loop interface fully. Do not exceed the 12000 RPM maximum speed rating. Licensed automotive refinishing technicians and trade professionals should follow applicable shop safety and ventilation requirements when sanding in wet conditions.
