15U704 - Walter Enduro-Flex ALU 7-Inch Aluminum Grinding Flap Disc 40 Grit

High-Performance Aluminum Grinding Solution

The Walter Enduro-Flex ALU™ 7" Flap Disc (SKU: 15U704) represents a significant leap forward in abrasive technology for soft and heat-sensitive metals. Grinding aluminum has traditionally presented challenges for industrial operators, primarily due to the metal's tendency to melt and "load up" (clog) the abrasive surface, rendering standard discs useless long before their abrasive grain is depleted. Walter Surface Technologies addresses this specific pain point with a proprietary zirconia alumina grain blend and a specialized coating formulation that lubricates the cutting surface to prevent glazing.

This 40-grit disc is engineered for heavy stock removal and blending applications. It features Walter's innovative Eco-Trim™ backing, a trimmable plastic support that can be cut back to expose fresh abrasive flaps. This unique feature can extend the usable life of the disc by up to three times compared to conventional fiberglass-backed alternatives, offering substantial cost savings and reduced downtime for disc changes. The backing is also designed to absorb vibration, reducing operator fatigue during extended grinding sessions.

Crucial for industries such as aerospace, marine, and transportation, the Enduro-Flex ALU is guaranteed free of iron, sulfur, and chlorine. This ensures that the grinding process does not introduce contaminants that could lead to galvanic corrosion or structural weakness in the aluminum workpiece. By combining high removal rates with a cool cutting action, this tool maintains the integrity of the metal while delivering a superior surface finish.
