OVERVIEW

High-Performance Grinding for Industrial Fabrication

At Josef Gas, we know that efficiency in the shop translates directly to the bottom line. The Walter Allsteel Grinding Wheel (08C450) is engineered to meet the rigorous demands of professional metal fabricators who require versatility without compromising on performance. This 4-1/2 inch Type 27 wheel is a staple in industrial environments because it simplifies inventory and workflow; it is formulated to deliver exceptional results on both mild steel and stainless steel, reducing the need for operators to swap out abrasives when switching materials.

One of the standout features of the Allsteel line is its ability to cut freely and coolly. In high-production environments, heat buildup is a major enemy, particularly when working with stainless steel where heat tint and discoloration can lead to costly rework or passivation steps. The advanced grain structure of this wheel ensures that material is removed aggressively while keeping the workpiece temperature manageable. This "cool cut" technology not only protects the integrity of the metal but also prevents the wheel from glazing over, ensuring consistent bite throughout its lifespan.

Safety and durability are paramount in the heavy industrial sectors we serve. The Walter Allsteel wheel is constructed with a heavily reinforced bonding matrix that resists the bending and twisting forces common during heavy weld removal or beveling operations. This structural integrity provides peace of mind for operators working in challenging positions. With a 1/4-inch thickness, this wheel is built for heavy stock removal, making it ideal for grinding down heavy welds, chamfering edges for penetration, and general heavy-duty shaping. When you choose Walter abrasives from Josef Gas, you are investing in reduced downtime and superior finish quality.

Key Industrial Benefits

  • Versatility: One wheel for both steel and stainless applications reduces inventory complexity.
  • Cool Operation: Minimizes heat affected zones (HAZ) and discoloration on sensitive alloys.
  • Operator Safety: High-strength bonding resists breakage under heavy lateral pressure.

FAQ

The Walter Allsteel wheel is formulated for high performance on both mild steel and stainless steel. It is designed to cut coolly, making it safe for stainless applications where heat buildup is a concern.

This wheel features a standard 7/8-inch arbor, which is compatible with most standard 4-1/2 inch and 5-inch angle grinders.

This is a Type 27 (depressed center) grinding wheel. It is designed for grinding on the face/bottom edge of the wheel at an angle, typically between 15 and 30 degrees relative to the workpiece.

No, this is a 1/4-inch thick grinding wheel designed for stock removal and shaping. For cutting applications, you should use a Type 1 or Type 27 cutting wheel (typically 1/16-inch or thinner), such as the Walter Zipcut.

No, the Allsteel formulation is designed to be free of iron, sulfur, and chlorine contaminants that typically cause corrosion on stainless steel, provided the wheel hasn't been previously used on carbon steel.

While you should always check the label on the specific disc, standard 4-1/2 inch grinding wheels like the 08C450 are typically rated for a maximum of 13,300 RPM.

Stainless steel conducts heat poorly, meaning heat builds up quickly at the grind point. A cool-cutting wheel prevents this heat buildup, which avoids warping the metal and prevents 'heat tint' or discoloration that can reduce corrosion resistance.

These wheels are typically sold individually, but the standard factory carton quantity is usually 25 wheels per box.
