Walter ZIP GRIND 4-Inch Die Grinder Wheel Type 1

Tough Wheel for Tight Spots

When you need to hog out metal in a tight corner or prep a small weld, you grab your die grinder—and you need a wheel that can keep up. The Walter ZIP GRIND 4-inch wheel is built exactly for that. It’s a beefy 1/2-inch thick slab of abrasive that fits right onto your straight shaft grinder (3/8" arbor) and goes to work immediately. Unlike cheaper stones that bounce around or wear down in minutes, this wheel bites into the metal and holds its shape, letting you grind down heavy welds or deburr thick plate with confidence.

One of the biggest headaches with die grinding is heat buildup. This Walter wheel runs noticeably cooler than standard abrasives, which means you aren't scorching your stainless steel or ruining the temper on your parts. It cuts fast and smooth, so you aren't fighting the tool all day. Plus, it's guaranteed not to contaminate your stainless work with rust-causing iron, so it's safe for code work and sanitary welding jobs.

This isn't a delicate finishing wheel; it's a workhorse. Use it for notching, shaping, and heavy stock removal. The 36-grit composition is aggressive enough to strip away scale and slag but controlled enough to leave a workable surface. If you are tired of changing out small wheels every ten minutes, switch to the ZIP GRIND and get more done with less downtime.
