Walter HP 5-Inch Type 28 Spin-On Grinding Wheel for Steel

Grind Welds Faster and Smoother

When you are tackling heavy welds on structural steel, you need a wheel that bites hard and lasts long. The Walter HP Type 28 Spin-On Grinding Wheel is built for welders who demand performance without the hassle. This 5-inch wheel features Walter's legendary HP formulation, which is tuned to rip through steel scale and heavy weld beads without bogging down your grinder. Whether you are prepping a joint or smoothing out a cap pass, this wheel gives you the aggressive removal you need to get the job done quickly.

The unique Type 28 saucer shape is a game-changer for comfort and control. Because the wheel is slightly conical, you don't have to hold your grinder at a steep angle. You can work flatter to the surface, which feels more natural and helps you avoid gouging the base metal. This shape is perfect for contouring and blending, giving you a smoother finish with less effort. Plus, the 1/4-inch thickness provides the durability needed for heavy edge grinding and deburring tasks.

Forget about hunting for your pin wrench every time you need to swap a disc. This wheel comes with Walter's Spin-On system—a built-in 5/8"-11 threaded hub. You just spin the old wheel off and spin the new one on by hand. It tightens itself as you work, ensuring a secure fit every time. The integrated hub also balances the wheel perfectly, cutting down on the vibration that leaves your hands tingling at the end of the day. Upgrade your grinding game with a wheel that works as hard as you do.
