09A306 - Walter 3-Inch Spin-On Flap Disc 60 Grit Type R

High-Efficiency Small Diameter Abrasive Solution

The Walter 09A306 Spinlock Flap Disc represents a premium solution for industrial surface finishing, specifically engineered to address the challenges of working in confined spaces where standard angle grinders cannot operate. With a 3-inch diameter and a 60 grit abrasive profile, this consumable is designed to bridge the gap between heavy stock removal and fine surface blending. It is an essential component for MRO (Maintenance, Repair, and Operations) inventories and fabrication shops that require versatility and speed. The disc is formulated to perform exceptionally well across a wide range of materials, including mild steel, stainless steel, and aluminum, allowing procurement managers to consolidate their abrasive stock codes and reduce inventory complexity.

A key technical advantage of this product is the Spinlock fastening system. Compatible with standard Type R (roll-on/roll-off) backing pads, the integrated plastic button allows for instantaneous mounting and dismounting without the use of tools. In high-throughput manufacturing environments, this reduction in changeover time directly translates to increased labor efficiency and reduced downtime. The mechanical connection is secure and concentric, ensuring smooth operation even at high rotational speeds typically associated with die grinders. Furthermore, the plastic backing is a critical quality assurance feature; unlike metal-hubbed discs, it eliminates the risk of metallic contamination on the workpiece, which is vital for maintaining corrosion resistance in stainless steel applications.

The layered flap construction of the Walter 09A306 offers significant cost-in-use benefits over traditional single-layer sanding discs. As the abrasive grains wear down, new, sharp grains are exposed from the layers below, maintaining a consistent cut rate throughout the life of the product. This self-sharpening characteristic not only extends the service life of each disc but also ensures a uniform finish from the first part to the last. For operations focused on cost reduction and quality control, the Walter Spinlock Flap Disc delivers a reliable, high-performance grinding experience that minimizes rework and maximizes productivity.

Safety and operator comfort are also addressed in the design. The flap configuration naturally dampens vibration compared to rigid grinding wheels, reducing the risk of hand-arm vibration syndrome (HAVS) during prolonged use. The cool-cutting nature of the abrasive formulation prevents heat buildup, protecting the structural integrity of the base metal and reducing the likelihood of heat tinting, which often requires secondary cleaning processes.
