Frequently Asked Questions:

• What materials is this flap disc designed for?
  It's best suited for mild steel, alloy steel, and general metalwork where coarse sanding or grinding is required.

• Can I use this flap disc on wood or plastic?
  While possible, this disc is intended for metal surfaces and may be too aggressive for softer materials.

• What’s the ideal grinding angle?
  For best results, maintain a 15 to 25 Degree angle when grinding. This provides optimal contact with the surface.

• Is this compatible with my grinder?
  It fits all 115mm (4½ inch) angle grinders that accept a 22.2mm centre.

• What’s the difference between this and 60 grit?
  80 grit is coarser and removes more material faster. 60 grit gives a slightly smoother finish while still grinding effectively.

• What safety precautions should I follow?
  Always wear safety goggles, gloves, a dust mask, and hearing protection when operating angle grinders.
