4-1/2 Inch 120 Grit Enduro-Flex Stainless Blending Disc

Smooth Finishes on Stainless and Aluminum

When you are finishing high-value parts, the last thing you need is a disc that clogs up or burns the workpiece. The Walter 15Q462 Enduro-Flex Stainless™ Flap Disc is built to solve the specific headaches welders face when working with stainless steel and aluminum. This 120 grit disc is your go-to tool for achieving a smooth, professional finish in a single step, eliminating the need to switch between multiple grinding wheels and sanding discs. It bites into the metal enough to blend welds but runs cool enough to prevent the dreaded "blueing" or heat tint that ruins the look of stainless steel.

One of the biggest frustrations in the shop is throwing away a flap disc that still has plenty of grit left in the center just because the edge is worn down. Walter solves this with their Eco-Trim™ backing. When the flaps wear down to the edge of the backing, you don't toss the disc—you simply trim the backing against a piece of scrap metal to reveal fresh abrasive underneath. This simple feature can triple the life of a single disc, keeping more money in your pocket and fewer discs in the trash bin. The backing is made from plant fibers, making it easy to trim safely without shattering.

Comfort matters when you have a grinder in your hand all day. The Enduro-Flex Stainless™ is designed to run quietly and without the aggressive vibration found in cheaper, harder discs. It features a raised hub that fits securely on your standard 4-1/2" grinder flanges. The special non-loading formula is a lifesaver for aluminum work, preventing the disc from gumming up and losing its cut. Whether you are polishing a tank, finishing a railing, or prepping aluminum for paint, this disc delivers a consistent finish every time.
