United Abrasives-SAIT 20063 A24R General Purpose/Long Life Grinding Wheel (Type 27/Depressed Center) 4 1/2″ x 1/4″ x 7/8″, 25-Pack

Description

Product Overview

The United Abrasives SAIT 20063 A24R is a high‑performance surface grinding wheel engineered for general‑purpose metalworking. Measuring 4½ inches in diameter, ¼ inch in thickness and 7⁄8 inch in arbor size, this wheel fits a wide range of grinders, including angle, bench, and die models. Its abrasive grain is made from premium aluminum oxide, a coarse grit (60) that excels at rapid stock removal on ferrous metals such as steel, iron, and welds. The wheel is internally reinforced with a dense fiberglass matrix, delivering exceptional structural integrity and safety under the maximum rotational speed of 13,300 RPM. Each wheel weighs only six ounces, yet the fiberglass reinforcement provides a long‑life, non‑hubbed design that resists cracking and delamination, making it a reliable choice for high‑volume production environments.

Usage

In industrial workshops, automotive repair bays, and fabrication shops, the SAIT 20063 wheel is used for a variety of grinding tasks. Its coarse aluminum oxide grit quickly removes excess material, allowing technicians to shape, bevel, and finish workpieces with precision. The wheel’s 4½‑inch cutting diameter provides ample contact area for efficient material removal while maintaining control for fine detail work. Because the wheel is compatible with standard 7⁄8‑inch arbors, it can be mounted on most common grinders without the need for adapters. Whether you are preparing weld seams for inspection, deburring castings, or smoothing rough edges on structural steel, this wheel delivers consistent performance. The 25‑pack packaging reduces the frequency of wheel changes, keeping production lines moving and minimizing downtime.

FAQ

What types of metal are best suited for this wheel?

The wheel is optimized for ferrous metals, including carbon steel, alloy steel, cast iron, and welded joints. Its coarse aluminum oxide grit quickly removes stock while maintaining a smooth finish.

Can I use this wheel on a die grinder?

Yes. The wheel’s 7⁄8‑inch arbor is compatible with most die grinders, angle grinders, and bench grinders that accept a standard 7⁄8‑inch spindle.

What safety precautions should I follow?

Always wear appropriate eye protection, ensure the wheel is properly mounted, and never exceed the rated maximum speed of 13,300 RPM. Inspect the wheel for cracks before each use and follow OSHA and ANSI safety guidelines.

How does the fiberglass reinforcement affect performance?

The fiberglass core adds structural rigidity, preventing wheel deformation under load. This results in a longer service life, reduced vibration, and a safer grinding experience.

What is included in the 25‑pack?

The package contains 25 individual grinding wheels, each individually wrapped for protection. No additional components such as batteries or adapters are required.
