15R456 - Walter Enduro-Flex 4-1/2" Grit 60 Flap Disc with Eco-Trim

Grind and Finish in One Step

Stop wasting time switching between a grinding wheel and a sanding disc. The Walter Enduro-Flex 4-1/2" Flap Disc (15R456) is your go-to solution for taking a weld from rough to ready in a single pass. With a versatile 60 Grit Zirconium formula, this disc bites into the metal to knock down welds quickly but is engineered to leave a smooth, paint-ready finish. It is the ultimate tool for welders working on steel or stainless steel who demand efficiency without sacrificing the quality of the final appearance.

Get More for Your Money

We all know the frustration of throwing away a flap disc that still has plenty of abrasive left in the center. Walter solved this with their Eco-Trim™ backing. When the flaps wear down to the edge of the plastic backing, you don't toss it—you trim it. By simply running the backing against a sharp metal edge, you cut away the plastic to reveal fresh, unused abrasive grain. This feature essentially gives you three discs in one, keeping you grinding longer and buying replacements less often.

Smooth Running, Cool Cutting

Heat and vibration are the enemies of a good finish and a comfortable day's work. The Enduro-Flex disc features a built-in cooling agent that prevents the workpiece from overheating, reducing the risk of warping or discoloration on sensitive materials like stainless steel. The balanced design and shock-absorbing backing mean less chatter and less fatigue for your hands and arms. Equipped with a 5/8"-11 threaded hub, it spins right onto your grinder without fumbling for a flange nut, getting you back to work in seconds.
