22042 - SAIT 22042 6-Inch A24R Pipeline Cutting & Grinding Wheel, Type 27 (25-Pack)

High-Performance Pipeline Fabrication Abrasive

The United Abrasives / SAIT 22042 A24R Pipeline Wheel is a specialized abrasive tool engineered to meet the rigorous demands of the pipeline industry. Designed as a hybrid solution, this 6-inch Type 27 wheel features a 1/8-inch thickness that bridges the gap between standard cutting discs and heavy-duty grinding wheels. This unique dimensional profile allows operators to perform cutting operations and immediate light grinding, such as root pass cleaning, without the downtime associated with tool changes. Manufactured in the United States, the wheel utilizes a premium aluminum oxide grain structure bonded with a hard, durable resin matrix (A24R) that resists loading and ensures a consistent cut rate throughout the wheel's life.

Structural integrity is paramount in pipeline applications where wheels are often subjected to lateral stress. The SAIT 22042 is reinforced with the highest quality fiberglass mesh, providing the necessary tensile strength to withstand the forces of angle grinding at speeds up to 10,200 RPM. The depressed center (Type 27) design facilitates a proper approach angle for grinding beads and smoothing welds, while the 7/8-inch arbor ensures compatibility with a wide range of industrial angle grinders. This wheel is specifically formulated for ferrous metals, including structural steel and cast iron, making it an essential consumable for MRO operations, field fabrication, and heavy industrial welding environments.

By consolidating cutting and grinding functions, the SAIT 22042 optimizes workflow efficiency. In pipeline construction, where the "bead" or root pass requires precise preparation before subsequent weld layers are applied, the ability to notch, cut, and grind with a single abrasive significantly reduces cycle times. The A24R grade offers a balanced hardness that provides aggressive material removal without sacrificing wheel longevity, ensuring that each of the 25 wheels in this pack delivers maximum value and performance.
