OVERVIEW

Stop Clogging and Start Grinding

If you work with aluminum, you know the frustration of a fresh flap disc turning into a useless, glazed-over coaster in a matter of minutes. Aluminum is soft, sticky, and loves to melt right into the grain of standard abrasives. The Walter Enduro-Flex ALU™ 7" x 7/8" Grit 80 Flap Disc is the answer to that headache. Designed specifically for welders and fabricators who demand performance, this disc features a specialized coating that acts as a lubricant, preventing the aluminum from sticking to the flaps. The result? A disc that keeps cutting aggressively and runs cool, leaving you with a smooth, professional blend without the constant need to swap out consumables.

The 15U708 isn't just about non-loading performance; it's about getting the most bang for your buck. Walter has equipped this disc with their signature Eco-Trim™ backing. Have you ever thrown away a flap disc that still had plenty of abrasive in the center, just because the edge was worn down? With Eco-Trim™, you can simply trim the plastic backing against a piece of scrap metal to reveal fresh, unused abrasive flaps underneath. This simple feature can triple the life of a single disc, keeping more money in your pocket and keeping you working longer without interruption.

This 80-grit version is perfect for that sweet spot between material removal and surface finishing. It’s aggressive enough to take down light welds and imperfections but leaves a finish that is easy to polish or prep for painting. The zirconia alumina grain is tough and self-sharpening, ensuring that the disc cuts just as well at the end of its life as it did at the start. Whether you are building aluminum boat hulls, truck boxes, or custom architectural pieces, the Enduro-Flex ALU™ gives you the control and longevity you need to produce top-tier work.

Why Welders Love It

  • No More Glazing: Keeps cutting where other discs slide and burn.
  • Extended Life: Trim the backing to use every bit of the flap.
  • Cool Running: Reduces heat input to prevent warping thin aluminum sheets.
  • Smooth Finish: 80 grit provides a clean, consistent blend.

FAQ

Aluminum is a soft metal with a low melting point. Standard flap discs often cause the aluminum to melt and clog (load) the abrasive grains, rendering the disc useless quickly. The Enduro-Flex ALU has a special coating to prevent this loading.

The Eco-Trim backing is made of a special composite that can be trimmed down. As the abrasive flaps wear down to the edge of the backing, you can grind the backing itself against a sharp metal edge to reduce its diameter, exposing fresh abrasive material underneath.

The maximum safe operating speed for the 7-inch Enduro-Flex ALU disc is typically rated at 8,600 RPM. Always verify the rating printed on the disc before use.

Yes, the Enduro-Flex ALU is guaranteed to contain less than 0.1% Iron, Sulfur, and Chlorine, making it safe for use on stainless steel and aluminum without causing cross-contamination or corrosion.

While it can physically grind steel, it is formulated specifically for soft metals like aluminum. Using it on hard steel may wear the coating and abrasive prematurely compared to a disc designed for steel, like the standard Enduro-Flex.

This specific SKU (15U708) requires a 7/8" arbor, which is standard for most 7-inch angle grinders.

Grit 40 is for heavy stock removal. Grit 60 is a general-purpose grit for removal and blending. Grit 80 (this product) is best for light blending and preparing the surface for a final finish.

No, this is a Type 29 (conical) or Type 27 (flat) style flap disc with an integrated backing plate. It mounts directly to the grinder using the grinder's flange nut.
