07Q504 - Walter Enduro-Flex 5-Inch Flap Disc 40 Grit with 5/8-11 Hub

Walter Enduro-Flex One-Step Finishing Disc

The Walter 07Q504 Enduro-Flex Flap Disc represents the pinnacle of abrasive technology for industrial metalworking. Designed to replace the traditional two-step process of using a grinding wheel followed by a fiber disc, the Enduro-Flex allows operators to grind welds and finish surfaces in a single pass. This specific model features a 5-inch diameter and a coarse 40 grit abrasive, making it ideal for heavy stock removal, weld blending, and edge chamfering on both steel and stainless steel components.

What sets the Enduro-Flex apart is its patented Eco-Trim backing. Unlike standard fiberglass backings that must be discarded once the abrasive wears down to the edge, the Eco-Trim backing is made of a specialized polymer that can be trimmed away. This exposes fresh abrasive material underneath, effectively extending the life of the disc by up to three times compared to conventional competitors. This feature not only reduces consumable costs but also minimizes downtime associated with frequent disc changes.

Engineered for high-performance environments, this disc features a built-in 5/8"-11 Spin-On hub, ensuring quick and secure mounting to standard angle grinders without the need for flange nuts or wrenches. The abrasive composition is formulated to cut cool, significantly reducing the risk of heat discoloration or warping on heat-sensitive alloys like stainless steel. With a maximum rating of 12,200 RPM, the 07Q504 delivers consistent, vibration-free performance that enhances operator safety and comfort during prolonged use.
