Product Overview:

The Blue Spot Tools 40 Grit Zirconium Flap Disc is built for industrial-grade performance, making it ideal for aggressive grinding, weld removal, and heavy-duty surface prep on stainless steel, carbon steel, and alloy materials. Designed to be used with all standard 4½" angle grinders, this disc features a Type 29 conical profile for superior contact on curved and contoured surfaces.

Constructed from premium zirconium oxide, this flap disc outperforms conventional aluminium oxide by delivering longer life, cooler grinding, and faster material removal. The depressed centre ensures stability and better control when working at the optimal grinding angle of 15 to 25 degree.

Frequently Asked Questions:

• What is the main benefit of zirconium over aluminium oxide?
  Zirconium is more durable, cuts cooler, and lasts longer—ideal for tougher metals like stainless steel.

• Can this be used on wood or plastic?
  While it’s engineered for metal, it can be used on harder woods—but avoid plastics as they may melt under heat.

• Is this disc compatible with a cordless angle grinder?
  Yes, as long as the grinder supports 115mm discs with a 22.2mm centre, it's compatible.

• Is 40 grit too coarse for polishing?
  Yes. 40 grit is intended for stock removal—for polishing, use finer grits like 120 grit or a dedicated polishing mop.

• Can it be used on aluminium?
  Yes, but keep the grinder speed lower and avoid overheating, as aluminium loads discs quickly.
