OVERVIEW

Professional Grade Concrete and Masonry Grinding

The Walter 08E450 4-1/2" Grinding Wheel is a specialized abrasive tool designed specifically for the rigorous demands of the construction and masonry industries. Unlike standard metal-grinding wheels, this product utilizes high-quality silicon carbide grain, which is essential for effectively grinding non-ferrous materials such as concrete, stone, masonry, and cast iron. The sharp, hard crystalline structure of the grain ensures that the wheel bites into the material immediately, delivering a high removal rate without the glazing issues often encountered when using aluminum oxide wheels on these substrates.

Safety and durability are paramount in the design of Walter abrasives. This wheel features multiple layers of high-strength reinforcement, providing structural integrity that withstands the lateral forces applied during heavy grinding. The bonding matrix is engineered to be tough yet sufficiently soft to allow fresh grain to be exposed continuously, maintaining a consistent cut rate throughout the life of the wheel. This balance of longevity and performance makes it a cost-effective solution for contractors who need reliable tools for surface preparation, smoothing concrete seams, or shaping stone.

For industrial applications where efficiency is key, the 08E450 offers a superior user experience. The wheel is balanced to minimize vibration, reducing operator fatigue during extended use. Whether you are cleaning up castings in a foundry or leveling concrete surfaces on a job site, this Walter grinding wheel delivers the aggressive performance required to get the job done quickly. It is compatible with standard 4-1/2" angle grinders with a 7/8" arbor, making it a versatile addition to any professional tool crib.

Key Applications

  • Grinding and smoothing concrete surfaces

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.
