06B604 - Walter Enduro-Flex 6-Inch Grit 40 Spin-On Flap Disc

Grind and Finish in One Step with Walter Enduro-Flex

Upgrade your grinding game with the Walter 06B604 Enduro-Flex™ 6" Flap Disc. If you are tired of constantly switching between aggressive grinding wheels and softer finishing discs, the Enduro-Flex is your answer. This Grit 40 disc is aggressive enough to knock down heavy welds quickly but engineered to leave a smooth, paint-ready finish. The integrated Spin-On 5/8"-11 hub makes attaching it to your grinder effortless—just spin it on and you are ready to work, no tools required.

Welders know that vibration and heat are the enemies of a good day's work. Walter has addressed this with a vibration-free design and a special top coating that cools the contact patch while lubricating the cut. This means you can grind longer without the "chatter" that numbs your hands, and you avoid heat discoloration on sensitive materials like stainless steel. The zirconium grain stays sharp, biting into the metal rather than rubbing against it, which speeds up your workflow significantly.

Get 3x More Life Out of Your Disc

The standout feature of this disc is the Eco-Trim™ backing. Usually, when the edge of a flap disc wears out, you have to toss it, even though there is plenty of good abrasive left in the middle. With Enduro-Flex, you simply trim the plastic backing to expose that fresh grain, effectively restoring the disc to like-new performance. This can triple the life of a single disc, keeping more money in your pocket and fewer used discs in the trash. It is safe, easy to do, and makes the Enduro-Flex one of the most cost-effective choices for professional welders.

Perfect for steel and stainless steel, this disc handles curved surfaces and flat grinding with equal ease. The raised hub design ensures it fits perfectly on standard grinders without interference. Choose the Walter Enduro-Flex for a smoother grind, a better finish, and a disc that lasts as long as you do.
