Silverline 80 grit Zirconium Flap Disc 100mm – Key FAQs

• What is 80g best used for on a flap disc?
  80g is ideal for general grinding and finishing—removing light weld marks, blending edges and preparing metal surfaces before painting or coating without being overly aggressive.

• Can I use this flap disc on stainless steel?
  Yes. It’s suitable for stainless steel, mild steel, cast iron and many alloys. Use controlled pressure to help reduce heat and maintain a clean finish.

• Do I need a backing pad with this flap disc?
  No. This flap disc fits directly to a compatible angle grinder, which makes set-up quicker and reduces the need for additional accessories.

• How does a flap disc compare to a grinding wheel?
  Flap discs can grind and blend at the same time, often leaving a smoother finish and making it easier to feather edges and tidy welds with more control.

• How do grit grades work for flap discs?
  Lower grit numbers are coarser for faster removal (around 40–60), while higher numbers are finer for finishing (up to around 120). Choose the grit to match the stage of work.

• What safety precautions should I take when using flap discs?
  Wear eye and face protection, gloves and suitable PPE. Ensure the guard is fitted, check the disc for damage before use, and avoid excessive pressure to reduce kickback and overheating.
