15W704 - Walter Allsteel 7-Inch Flap Disc Grit 40 with Trimmable Backing

High-Performance Abrasive Solution for Steel Fabrication

The Walter Surface Technologies Allsteel™ Flap Disc (SKU: 15W704) is engineered to meet the rigorous demands of industrial metalworking. Designed specifically for use on steel, this 7-inch abrasive disc utilizes a proprietary blend of zirconia alumina grains. This advanced formulation ensures that the disc self-sharpens during operation, exposing fresh cutting edges as the abrasive wears down. The result is a consistent, high material removal rate that persists throughout the lifespan of the product, making it a highly efficient choice for workshops focused on productivity and throughput.

One of the standout technical features of the Allsteel™ line is its trimmable backing. In standard flap discs, the backing plate often interferes with the workpiece before the abrasive cloth is fully consumed, leading to premature disposal and material waste. The Walter Allsteel™ design allows the operator to trim the backing, thereby exposing unused abrasive flaps near the center of the disc. This innovation significantly extends the service life of each unit, providing a better cost-per-weld ratio and reducing overall consumable inventory requirements.

With a coarse 40 grit rating, this disc is optimized for aggressive stock removal tasks. It excels in applications such as heavy deburring, leveling weld seams, and shaping metal edges. The 7-inch diameter provides a large contact area, making it suitable for processing larger workpieces and long weldments efficiently. The disc is compatible with standard 7-inch angle grinders featuring a 7/8-inch arbor, ensuring seamless integration into existing tool fleets. By requiring less downward pressure to achieve effective cutting, the Allsteel™ disc also contributes to reduced machine wear and lower energy consumption.

For procurement managers and fabrication supervisors, the Walter 15W704 represents a strategic balance between performance and economy. It delivers the aggressive bite needed for heavy structural steel work while offering the longevity required to keep consumable costs in check. Whether used for preparing surfaces for painting or blending sharp corners, this flap disc provides a reliable, industrial-grade solution for general purpose steel grinding.
