OVERVIEW

High-Performance Stainless Steel Grinding with Type 28 Geometry

The Walter HP Stainless Grinding Wheel (SKU: 08F451) represents a pinnacle in abrasive engineering, specifically tailored for the rigorous demands of stainless steel fabrication. This 4-1/2 inch by 1/4 inch wheel features the unique Type 28 "saucer" shape. Unlike standard Type 27 wheels, the Type 28 geometry allows operators to grind at a shallower angle (typically 15 to 30 degrees). This flatter approach increases the contact area between the abrasive and the workpiece, resulting in a smoother finish and more controlled stock removal. It is an ideal choice for welders and fabricators who need to remove heavy welds or shape metal without gouging the surface.

One of the standout features of this wheel is the integrated Spin-On mounting system. This 5/8-11 threaded hub is built directly into the wheel, ensuring perfect centering every time it is mounted to a grinder. By eliminating the need for a separate flange and locking nut, the Spin-On system drastically reduces vibration. Less vibration means less operator fatigue, reduced risk of White Finger Syndrome, and a longer lifespan for your power tools. Furthermore, the tool-free mounting allows for lightning-fast wheel changes, keeping downtime to an absolute minimum in high-production environments.

Formulated specifically for stainless steel applications, the Walter HP Stainless wheel is guaranteed free of iron, sulfur, and chlorine (Fe, S, Cl < 0.1%). This purity is critical when working with high-grade stainless alloys, as it prevents cross-contamination that could lead to premature corrosion or rust spots on the finished product. The bond matrix is designed to cut cool, preventing heat discoloration and warping on heat-sensitive materials. Whether you are deburring, shaping, or preparing weld edges, this wheel delivers consistent, aggressive cutting power throughout its long service life.

In industrial settings where precision and efficiency are paramount, the Walter 08F451 offers a superior solution. Its combination of ergonomic geometry, vibration-dampening mounting, and contaminant-free chemistry makes it a top-tier choice for aerospace, food processing equipment, and pharmaceutical tank fabrication.

FAQ

Type 27 wheels have a flat profile with a depressed center, typically used at a 30-45 degree angle. Type 28 wheels have a saucer (concave) shape, allowing for grinding at shallower angles (15-30 degrees), which provides greater surface contact and operator comfort.

The Spin-On hub has a standard 5/8"-11 thread, which fits most standard 4-1/2" and 5" North American angle grinders. It does not require a backing flange or lock nut.

Yes, the Walter HP Stainless wheel is contaminant-free (Fe, S, Cl < 0.1%), making it safe for use on stainless steel intended for food or pharmaceutical applications where corrosion resistance is critical.

Yes, you can use it on mild steel, but it is formulated specifically for stainless steel. Using it on mild steel may result in faster wear compared to a wheel designed specifically for carbon steel.

The maximum safe operating speed is typically 13,300 RPM for 4-1/2" wheels, but you should always verify the RPM rating printed on the actual wheel label before use.

No, the Spin-On design allows for hand-tightening. The rotation of the grinder self-tightens the wheel during use, and it can usually be removed by hand or with minimal force.
