OVERVIEW

Industrial Grade General-Purpose Grinding Solution

The Pferd 62703 is a premium-quality fibre disc designed to meet the rigorous demands of industrial metalworking and maintenance operations. Manufactured by Pferd, a global leader in abrasive solutions, this disc utilizes a robust Aluminum Oxide (A) grain structure. Aluminum Oxide is the industry standard for general-purpose grinding because of its toughness and durability. It is particularly effective on carbon steel, cast iron, and non-ferrous metals, making it a versatile inventory item for MRO cribs and fabrication shops. The 36 grit configuration classifies this disc as a coarse abrasive, engineered specifically for aggressive stock removal, heavy weld leveling, and surface preparation where speed and material removal rates are prioritized over surface finish.

Structurally, the disc is built upon a heavy-duty vulcanized fibre backing. This backing material is critical for safety and performance, as it provides the necessary rigidity to withstand the high contact pressures often applied during angle grinder operations. Unlike lighter paper or cloth-backed discs, the vulcanized fibre resists tearing and deformation, ensuring that the abrasive surface remains in optimal contact with the workpiece. The grain is bonded to this backing using a high-strength resin system, which helps retain the abrasive particles even under the high heat generated during aggressive grinding. This construction minimizes grain shedding and extends the service life of the disc, reducing the frequency of changeovers and downtime for operators.

This specific model features a 7-inch diameter and a standard 7/8-inch arbor hole, making it compatible with a wide range of pneumatic and electric angle grinders commonly found in industrial environments. It is designed to be used with a corresponding backing pad, which supports the disc and allows for proper flexibility and contouring. For procurement managers and tool crib supervisors, the Pferd 62703 represents a cost-effective solution that does not compromise on safety or performance. It delivers consistent results across various applications, from removing mill scale and rust to grinding down heavy weld seams. By standardizing on Pferd's Aluminum Oxide line, facilities can ensure reliable throughput for their grinding and finishing processes.

FAQ

This Aluminum Oxide disc is best suited for general-purpose grinding on carbon steel, cast iron, and non-ferrous metals.

Yes, fibre discs are flexible and require a hard or medium rubber backing pad of the appropriate size (7 inch) to be used safely on an angle grinder.

This is a 36 grit disc, which is considered coarse. It is used for aggressive material removal, such as grinding down welds or removing heavy rust.

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

While Aluminum Oxide can grind stainless steel, it is not the optimal choice as it may generate excessive heat. Zirconia or Ceramic grain discs are recommended for stainless steel to prevent discoloration and contamination.

Fibre discs cut faster and run cooler than bonded grinding wheels, but they have a shorter lifespan. They are better for surface blending and removing material over a larger area.

No, vulcanized fibre discs are sensitive to humidity and moisture. They should be stored in a dry place to prevent curling and degradation.

Always check the printed rating on the disc or packaging, but generally, 7-inch fibre discs are rated for around 8,500 to 8,600 RPM. Never exceed the max RPM of the disc or the backing pad.
