06U454 - Walter Enduro-Flex Alu 4.5 Inch Grit 40 Flap Disc Spin-On

Stop Aluminum Clogging with Enduro-Flex Alu™

Grinding aluminum can be a frustrating task when your abrasives gum up and stop cutting after just a few minutes. The Walter Enduro-Flex Alu™ 4-1/2" Flap Disc (06U454) is the solution welders have been waiting for. Specifically formulated for soft, gummy metals, this Grit 40 disc features a specialized coating that prevents the aluminum from sticking to the abrasive grains. This means you can keep grinding longer with aggressive removal rates, without having to constantly swap out glazed discs.

Save Money with Trimmable Backing

Why throw away a disc that still has good abrasive left in the center? Walter's innovative Eco-Trim™ backing allows you to trim the plastic backing plate as the outer edge wears down. This simple feature exposes fresh abrasive material that is usually wasted on standard fiberglass-backed discs. By utilizing the full diameter of the flaps, you can get up to three times the life out of a single disc, lowering your overall shop consumable costs.

Fast Changes, Better Finish

Time is money in any fabrication shop. The Spin-On hub on this disc allows you to spin the disc on and off your grinder in seconds without searching for a pin wrench. The 40 grit zirconia alumina grain provides a rapid cut for stock removal while leaving a smooth finish that prepares the surface for welding or final polishing. Whether you are building aluminum trailers, repairing boat hulls, or fabricating custom tanks, the Enduro-Flex Alu™ is the reliable choice for professional results.
