09D202 - Walter 3-Inch Spinlock Aluminum Oxide Fiber Disc 24 Grit

High-Performance Material Removal with Walter Spinlock Technology

The Walter 09D202 Spinlock A/O Resin Fiber Disc is a premier abrasive solution designed for industrial professionals who demand efficiency and reliability. Engineered with high-quality Aluminum Oxide (A/O) grain, this 3-inch disc is formulated to deliver consistent cutting rates across a variety of metals, including carbon steel, cast iron, and aluminum. The 24 grit composition makes it an aggressive tool, perfectly suited for heavy stock removal, leveling welds, and stripping tough surface contaminants. Unlike standard discs that may glaze over or degrade quickly under heat, Walter's resin bonding technology ensures excellent grain retention and extended service life.

One of the standout features of this product is the integrated Spinlock mounting system. In high-throughput manufacturing and maintenance environments, downtime associated with changing abrasives can accumulate significantly. The Spinlock interface eliminates the need for locking nuts and wrenches, allowing operators to swap out worn discs or change grits in mere seconds. This quick-change capability, combined with the disc's small 3-inch footprint, makes it an indispensable tool for working in confined spaces, such as inside piping, channel iron, or complex machinery housings where larger angle grinders cannot reach.

Durability is at the core of the 09D202's design. The stiff fiber backing provides the necessary rigidity to withstand the high pressure required for aggressive grinding while maintaining enough flexibility to contour slightly to the workpiece. This balance reduces the risk of gouging while ensuring a uniform finish. Whether utilized for preparing surfaces for painting, removing heavy rust, or blending welds, this Walter abrasive disc offers a superior balance of cost, performance, and operational speed.

Key Technical Applications

• Heavy Stock Removal: Rapidly removes excess material from steel and iron castings.


• Weld Leveling: Efficiently grinds down weld beads in tight corners and restricted areas.


• Surface Preparation: Strips scale, rust, and paint to expose bare metal for fabrication.


• Maintenance & Repair: Ideal for general MRO tasks requiring quick abrasive changes.
