Product Overview:

The Blue Spot Tools 80 Grit Zirconium Flap Disc is a high-performance grinding and finishing solution designed for use with 4½ inch angle grinders. Ideal for light stock removal and smoothing, this fine grit disc provides excellent control and surface finish on a wide range of metals.

Its Type 29 conical shape allows users to work at an angle (typically 15 to 25 degree), making it perfect for edge blending, surface finishing, and refining previous grind marks. The zirconium oxide abrasive is more durable than standard aluminium oxide and is particularly effective on stainless steel, alloy steel, and carbon steel.

The depressed centre improves access to tight areas, while the 80 grit level makes it an ideal choice for finishing work before painting, polishing or coating.

FAQs – Frequently Asked Questions:

• Is 80 grit suitable for final finishing?
  Yes, 80 grit is ideal for smoothing and prepping surfaces before final coatings or polishing.

• Can I use this disc on stainless steel?
  Absolutely – zirconium is excellent for use on stainless and alloy steels, delivering longer life and reduced heat.

• What’s the difference between 60 grit and 80 grit?
  80 grit provides a finer finish, while 60 grit is more aggressive and better for shaping or stock removal.

• Is this compatible with my grinder?
  This disc fits all standard 115mm angle grinders with a 22.2mm centre bore.

• How does zirconium compare to aluminium oxide?
  Zirconium discs last longer, run cooler, and are better suited to tougher metals like stainless steel.
