3M™ Hookit™ Gold Disc Dust Free 216U 01073, 6 in, P400, 100 Discs/Carton, 4 Cartons/Case

The 3M Hookit Gold Disc 225P/216U represents a specialized sanding solution designed specifically for fine-grade finishing applications. Engineered with a lightweight A-weight paper backing, this disc excels at critical finishing tasks such as feather-edging surfaces, preparing substrates for primer application, and executing precision sanding on existing primer coats. Its carefully formulated composition makes it an ideal choice for the final preparation stages before painting or priming begins.

This disc utilizes a high-quality aluminum oxide mineral abrasive combined with an open coat construction methodology. The open coat design strategically spaces the abrasive grains apart from one another, creating channels that facilitate efficient evacuation of sanding dust and debris. This spacing mechanism serves a critical function in preventing the accumulation of sanding residue on the disc's surface, which would otherwise impede the cutting effectiveness of the abrasive grains and reduce overall sanding performance.

A specialized load-resistant coating applied to the abrasive grains enables the disc to maintain its cutting capability even when working with challenging materials such as paints and coatings that typically cause rapid clogging. This advanced formulation ensures sustained productivity throughout extended use cycles.

These engineered features collectively contribute to measurably increased productivity levels and reduced material waste, delivering superior value and performance for professional finishing applications.
