Walter ZIP 4-Inch Die Grinder Wheel Type 1

Grind Tight Spaces Without Losing Power

When you are deep in a fabrication project, sometimes your 4.5-inch angle grinder just won't fit where you need it. That is when you grab your die grinder, and if you want to move serious metal, you equip it with the Walter 11L433 ZIP™ Grinding Wheel. This isn't a delicate finishing wheel; it is a 1/4-inch thick slab of abrasive muscle designed to hog out material, notch steel, and smooth down heavy welds in tight corners. It gives you the aggressive bite of a larger wheel in a compact 4-inch package that fits right on your straight shaft grinder.

We all know the frustration of wheels that glaze over or turn your stainless steel blue from heat. Walter has solved that with the ZIP™ formulation. These wheels run surprisingly cool, meaning you can grind on stainless rails or tanks without worrying about ruining the finish or contaminating the metal. The bond is tough enough to resist crumbling under pressure but breaks down just fast enough to keep fresh, sharp grain exposed. This means you aren't fighting the tool; you are just guiding it while it does the work. The result is a smoother grind and less fatigue in your arms at the end of the day.

The 11L433 is built for the real world. It holds up to the high RPMs of pneumatic die grinders and doesn't wobble or vibrate like cheaper stones. Whether you are beveling a pipe end, cleaning up a root pass in a tight spot, or notching out a bracket, this wheel gives you the control and power you need. It is Fe-S-Cl free, so you can use it on any job site, including nuclear or food-grade stainless projects, without worrying about inspection failures due to contamination. Throw one in your bag and see the difference a quality wheel makes.
