OVERVIEW

Aggressive Grinding with Pferd 7" 24 Grit Fiber Discs

When you have a heavy weld to level or thick rust to strip, you need an abrasive that bites. The Pferd 62702 7-inch sanding disc is built for welders and fabricators who need to remove material fast. Featuring a coarse 24 grit Aluminum Oxide grain, this resin fiber disc is designed to dig in and hog out metal, saving you time and effort on the toughest grinding jobs. Whether you are prepping a surface for welding or cleaning up after a structural repair, this disc provides the aggressive cut you need.

The 7-inch size covers a large surface area, making it perfect for working on plate steel, tanks, and large structural beams. The tough fiber backing supports the grain, allowing you to apply pressure without the disc falling apart prematurely. While it is tough on steel, the aluminum oxide grain is also versatile enough to use on aluminum and wood, giving you one disc that can handle multiple stages of your project. It mounts easily to your 7-inch angle grinder using a standard backing pad and nut.

Don't waste time with discs that glaze over or lose their grit instantly. Pferd's manufacturing quality ensures that the grain stays sharp longer, providing a consistent scratch pattern and reliable performance from the first spark to the last. This is the go-to disc for the initial rough grinding stage where speed and stock removal are the top priorities.

Why Welders Choose This Disc

  • Fast Stock Removal: 24 grit is aggressive enough to flatten welds quickly.
  • Durable Backing: Resists edge tearing when grinding against corners or irregular surfaces.
  • Multi-Material Use: Works great on mild steel, aluminum, and other fabrication materials.

FAQ

You need a 7-inch angle grinder equipped with a compatible backing pad. The disc requires a backing pad to support it during use; it cannot be used directly on the grinder spindle without one.

24 grit is considered very coarse. It is designed for heavy stock removal, such as grinding down welds or stripping thick coatings, rather than finishing or polishing.

Yes, Aluminum Oxide discs can be used on aluminum, but for extended use on soft metals, you might experience loading (clogging). However, for general purpose rough grinding, it is suitable.

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

Aluminum Oxide (A) is a general-purpose grain best suited for carbon steel, ferrous metals, non-ferrous metals, and wood. It offers a good balance of cut rate and life for general applications.

Resin fiber discs can be sensitive to humidity and temperature. It is best to store them flat in a dry, climate-controlled environment (ideally 40-50% relative humidity) to prevent them from curling or becoming brittle.

No, the backing pad is sold separately. You must use a hard or medium density backing pad sized for 7-inch discs.

While specific RPM ratings can vary by batch, 7-inch resin fiber discs are typically rated for around 8,500 to 8,600 RPM. Always check the label on the specific disc and ensure your grinder does not exceed this speed.
