OVERVIEW

Walter HP XX Type 28 Grinding Wheel: Maximum Efficiency for Steel

The Walter HP XX™ (08K701) represents the pinnacle of grinding wheel technology, specifically engineered to lower production costs through superior performance. Designed for industrial environments where time and efficiency are critical, this 7-inch grinding wheel utilizes the latest advancements in abrasive grain and bonding systems. The result is a wheel that not only removes material faster than conventional abrasives but also lasts significantly longer, reducing the frequency of wheel changes and downtime.

This specific model features a Type 28 "saucer" shape. Unlike the flat Type 1 or the depressed center Type 27, the Type 28 profile allows for a flatter angle of attack relative to the workpiece. This can be particularly advantageous for smoothing large surfaces or accessing difficult geometries where a standard wheel might gouge or bind. The saucer shape provides excellent stability and control, allowing operators to apply the necessary pressure for heavy stock removal without compromising safety or finish quality.

The HP XX™ series is formulated specifically for steel. Whether you are deburring heavy plate, shaping structural components, or preparing weld edges, this wheel delivers aggressive bite and cool cutting action. By maximizing the removal rate (MRR), the HP XX™ directly impacts the bottom line, reducing the labor cost per part. For MRO professionals and fabrication shop managers, the Walter 08K701 is a strategic choice that prioritizes total cost of ownership over initial price point.

Key Industrial Benefits

  • Highest Removal Rate: Cuts through steel rapidly to improve throughput.
  • Extended Lifespan: bonding technology resists wear, providing more grinding time per wheel.
  • Cost Savings: Reduces overall grinding expenses by minimizing labor and consumable usage.
  • Type 28 Geometry: Unique saucer shape for specialized grinding angles and surface coverage.

FAQ

A Type 27 wheel has a depressed center and a flat profile, typically used at a 15-30 degree angle. A Type 28 wheel has a 'saucer' shape, which is concave. This allows for grinding at shallower angles (often 0-15 degrees) and provides better access and surface contact for specific blending applications.

The HP XX™ line is primarily optimized for steel to ensure the most cost-effective removal rates. While it can physically grind other metals, Walter offers specific product lines (like HP Stainless) that are formulated to prevent contamination and heat buildup on stainless steel.

This wheel has a diameter of 7 inches and a thickness of 1/4 inch, making it a standard size for heavy-duty angle grinders.

No, this is a bonded abrasive grinding wheel (Type 28). It mounts directly to the grinder using the appropriate flange or arbor nut. Backing pads are typically used for resin fiber discs or flap discs.

Always wear a face shield over safety glasses, hearing protection, heavy-duty gloves, and flame-resistant clothing. Ensure the grinder's guard is properly adjusted and never exceed the maximum RPM rating of the wheel.

In industrial grinding, the cost of the wheel is often minor compared to the cost of labor. The HP XX removes material faster (reducing labor time) and lasts longer (reducing downtime for wheel changes), resulting in a lower total cost per finished part.

No. Type 28 wheels are 1/4-inch thick and designed for grinding (stock removal). They should never be used for cutting (cutoff) applications, as the side load forces during cutting are different from grinding and can cause dangerous wheel failure.

While not explicitly detailed in the short description, standard 7-inch grinding wheels typically feature a 7/8" arbor hole. Always verify your grinder's spindle size before purchasing.
