OVERVIEW

Aggressive Cutting Power for Tough Welds

When you have heavy welds to level or thick scale to remove, you need an abrasive that bites back. The Pferd 62712 7-inch Fibre Disc is built for welders who demand speed and durability. Powered by Zirconia Alumina grain, this 24-grit disc cuts faster and lasts longer than standard sanding discs, helping you get the job done in record time. It is the perfect companion for your 7-inch angle grinder when tackling structural steel, tanks, or heavy machinery repairs.

The secret to this disc's performance lies in its Zirconia grain structure. Unlike standard abrasives that smooth out and stop cutting, Zirconia micro-fractures under pressure to reveal fresh, sharp points. This self-sharpening action means the disc stays aggressive right down to the backing. This is particularly important when working with tough materials like stainless steel or hard alloys where maintaining a high cut rate is essential to prevent work hardening.

Sold in a convenient pack of 25, these discs ensure you have plenty of stock for big projects. Remember, fibre discs require a compatible backing pad to function correctly. The flexible yet tough fibre backing allows the disc to contour slightly while providing the stiffness needed to drive the grain into the metal. Upgrade your grinding game with Pferd's reliable German engineering and experience the difference a premium abrasive makes on your daily grind.

Why Welders Choose Pferd Zirconia

  • Fast Weld Leveling: Tears through excess weld metal quickly, saving you arm fatigue.
  • Longer Life: Change discs less often thanks to the durable Zirconia bond.
  • Consistent Finish: Provides a uniform scratch pattern suitable for subsequent finishing steps.
  • Heavy Duty: Stands up to the heat and pressure of continuous grinding.

FAQ

Zirconia Alumina is tougher and more durable than Aluminum Oxide. It is self-sharpening and works best under higher pressure, making it ideal for heavy stock removal on harder metals.

Yes, resin fibre discs are flexible and must be used with a hard or medium backing pad of the appropriate size (7 inch) to support the disc during grinding.

This Pferd Zirconia disc is excellent for use on carbon steel, stainless steel, cast iron, and other ferrous metals.

This disc has a standard 7/8" center hole (arbor), which fits most standard 7-inch angle grinders.

24 grit is very coarse. It is designed for aggressive material removal, such as grinding down heavy welds or shaping metal, rather than finishing.

These discs are sold in a pack of 25.

While it can cut aluminum, Zirconia is optimized for ferrous metals. For aluminum, a disc with a specialized coating to prevent loading (clogging) is usually recommended.

Always check the backing pad and disc label, but generally, 7-inch fibre discs are rated for use on angle grinders with speeds up to 8,500 or 8,600 RPM.
