OVERVIEW

Heavy-Duty Grinding for Cast Iron and Stone

Expand the capabilities of your angle grinder with the Walter 08E450 Concrete Grinding Wheel. While most welders are accustomed to grinding steel, projects often require working with different materials like cast iron, brick, or concrete. This 4-1/2" Type 27 wheel is specifically formulated with silicon carbide grain to tackle these hard, non-ferrous materials with ease. Standard metal grinding wheels can glaze over and stop cutting when used on masonry, but the 08E450 is designed to break down at the optimal rate, keeping the cutting face sharp and aggressive.

Walter Surface Technologies is known for producing some of the safest and most durable abrasives on the market. This wheel is no exception, featuring heavy-duty reinforcement that meets strict safety standards. This is particularly important when grinding uneven stone or concrete surfaces where the wheel might be subjected to shock loading. The 1/4" thickness provides a stable platform for heavy stock removal, allowing you to grind down welds on cast iron or smooth out rough concrete edges without fear of wheel failure.

Comfort and control are critical for precision work. The Walter 08E450 is manufactured to strict tolerances to ensure it runs true, significantly reducing vibration and chatter. This allows for smoother grinding action and better surface finishes. Whether you are a professional fabricator repairing cast iron components or a tradesperson needing to modify masonry to fit a metal structure, this wheel provides the specialized performance you need. It fits all standard 4-1/2 inch angle grinders with a 7/8 inch arbor, making it an easy swap for your standard steel grinding wheels.

Performance Benefits

Aggressive Cut: Silicon carbide grain slices through hard masonry and cast iron.
Non-Loading: Resists clogging and glazing for continuous grinding.
Safety First: Reinforced construction for high-speed operation.

FAQ

It is not recommended. This wheel uses silicon carbide grain which is designed for masonry, stone, and cast iron. For steel, you should use an aluminum oxide wheel for better performance and life.

The arbor size is 7/8 inch, which is the standard size for most 4-1/2 inch angle grinders.

This is a Type 27 grinding wheel with a 1/4 inch thickness, designed primarily for grinding. For cutting, you should use a thinner cutting wheel (Type 1 or Type 27 cut-off wheel).

This wheel is specifically engineered for concrete, masonry, stone, and cast iron.

The maximum safe operating speed is typically 13,300 RPM. Always check the label on the wheel to confirm before use.

Silicon carbide is harder and sharper than aluminum oxide, allowing it to cut through hard, brittle materials like concrete and stone without dulling or glazing over as quickly.

It fits most standard 4.5 inch grinders that accept a 7/8 inch arbor. It does not fit grinders requiring a 5/8-11 threaded hub unless you use a compatible adapter nut.

These wheels are typically sold individually or in boxes of 25. Please check the quantity selector for purchasing options.
