OVERVIEW

Efficient Small-Scale Finishing with Walter Spinlock

The Walter 09A308 Spinlock Flap Disc is a specialized abrasive tool designed to bring the performance of high-quality flap discs to compact, hard-to-reach applications. Measuring 3 inches in diameter, this disc is engineered for precision work where standard angle grinders are too bulky to operate effectively. It features an 80 grit abrasive composition, which serves as an excellent middle-ground for industrial operators; it is aggressive enough to remove light stock and imperfections while fine enough to leave a smooth, paint-ready finish in a single pass. This dual-action capability makes it a "one-step" finishing solution, significantly reducing the time and cost associated with switching between aggressive grinding wheels and finer sanding discs.

A standout feature of this product is the integrated plastic "TR" button, part of Walter's Spinlock system. This quick-change mounting mechanism is compatible with standard Type R backing pads, allowing operators to swap out worn discs in seconds without the need for wrenches or keys. In high-volume production environments or maintenance operations where time is money, the ability to change abrasives instantly translates to substantial productivity gains. The plastic button also ensures a secure, vibration-free connection to the die grinder, enhancing operator comfort and control during delicate finishing tasks.

Constructed to withstand the rigors of industrial use, the 09A308 is versatile enough for use on all metals. Whether you are working with mild steel, stainless steel, or aluminum, the abrasive flaps wear down evenly to expose fresh cutting grain, ensuring consistent performance throughout the life of the disc. The flap design naturally runs cooler than solid grinding wheels, which is critical when working on heat-sensitive materials to prevent warping or discoloration. For MRO professionals and fabricators looking to optimize their small-part finishing processes, this Walter Spinlock disc offers a perfect balance of speed, convenience, and finish quality.

FAQ

The Spinlock system, often referred to as Type R or TR, is a quick-change mounting style featuring a plastic button on the back of the disc that screws directly into a compatible backing pad with a simple twist.

This disc is designed for use with a right-angle die grinder equipped with a 3-inch Type R (TR) backing pad.

80 grit is considered a medium-fine grade. It is better suited for blending, light stock removal, and finishing rather than heavy grinding. For heavy removal, a 40 or 60 grit would be more appropriate.

Yes, the Walter 09A308 is designed for use on all metals, including aluminum, steel, and stainless steel.

These discs are sold in packages of 10.
