DEWALT Grinding Wheel, Double Row, Diamond Cup, 4-1/2-Inch (DW4774)

Description

Product Overview

The DEWALT DW4774 is a 4-1/2‑inch double‑row diamond cup grinding wheel engineered for high‑speed material removal in demanding industrial and construction environments. Constructed with a heat‑treated steel body, the wheel resists deformation under heavy loads, while the diamond matrix—engineered with an extended‑performance formulation—offers up to 350 times the life of conventional abrasive wheels. The wheel’s dimensions (5 x 4.5 x 4 inches) and weight of 15.87 ounces provide a balanced feel that reduces user fatigue during prolonged use. Designed to fit standard 4‑inch angle grinders, the DW4774 delivers consistent performance on a variety of metals, including steel, stainless steel, and cast iron, making it a versatile tool for fabricators, welders, and maintenance professionals. Its double‑row configuration maximizes contact surface, ensuring aggressive cutting action while maintaining a smooth finish. The product is backed by DEWALT’s reputation for durability and reliability, and it holds a strong sales rank within the Surface Grinding Wheels sub‑category, reflecting its popularity among trade professionals.

Usage

This grinding wheel excels in environments where rapid material removal and long wheel life are critical. It is ideal for shaping, beveling, and finishing metal components in automotive repair shops, heavy‑equipment maintenance bays, and fabrication workshops. The wheel’s robust construction allows it to handle high‑speed applications on angle grinders up to 12,000 RPM, making it suitable for both handheld and bench‑mounted grinding stations. Whether you are preparing weld seams, removing rust, or smoothing rough edges on structural steel, the DW4774 provides the aggressive cutting action needed to complete the job efficiently. Its heat‑treated steel segments dissipate heat effectively, reducing the risk of thermal damage to the workpiece and extending the wheel’s service interval. The wheel also performs well in confined spaces where precision and control are essential, such as in shipyard repairs or pipeline maintenance. For DIY enthusiasts, the wheel offers a professional‑grade solution that simplifies complex metalworking tasks, delivering results comparable to larger, more expensive equipment.

FAQ

What types of metal can this wheel grind?

The DW4774 is suitable for a wide range of metals, including carbon steel, stainless steel, cast iron, and alloy steel. Its diamond matrix is designed to cut efficiently while minimizing heat buildup, which helps preserve the integrity of the workpiece.

Can I use this wheel on a bench grinder?

Yes, the wheel is compatible with both handheld angle grinders and bench‑mounted grinders that accept a 4‑inch wheel. Ensure the grinder is set to the recommended speed range (up to 12,000 RPM) and that the wheel is properly mounted and balanced before operation.

How often should I replace the wheel?

Because of the extended‑life diamond matrix, the wheel typically lasts many hours longer than conventional abrasive wheels. Replacement intervals depend on usage intensity, material hardness, and operating conditions, but most users find they can complete multiple projects before needing a new wheel.

Is the wheel safe for use on stainless steel?

Absolutely. The wheel’s design and material composition allow it to cut stainless steel effectively while controlling heat, which reduces the risk of discoloration or warping of the material.

What warranty does DEWALT provide?

DEWALT offers a limited warranty that covers manufacturing defects for the life of the product. If you encounter any issues related to workmanship or material quality, you can contact DEWALT customer service for a replacement or repair.
