Silverline 115mm Aluminium Oxide Flap Disc 60 Grit – Key FAQs

• What is 60g best used for on a flap disc?
  60 grit is a strong all-round choice for grinding and blending—ideal for weld dressing, stock removal and surface preparation while still leaving a cleaner finish than very coarse grades.

• Do I need a backing plate with this 115mm flap disc?
  No. This flap disc mounts directly onto a compatible 115mm angle grinder, so no additional backing plate is required.

• What materials can I use this disc on?
  It’s suitable for steel, cast iron and alloys, and can also be used on fibreglass, wood and painted surfaces depending on the task and finish required.

• What does “self-renewing” mean on a flap disc?
  As the abrasive flaps wear down, fresh abrasive is exposed, helping maintain cutting performance over the life of the disc.

• Why is the 13,300rpm rating important?
  It’s the maximum safe operating speed for the disc. Always confirm your grinder’s no-load RPM is at or below the disc rating before use.

• How do I choose between 40, 60 and 80 grit flap discs?
  Use 40 grit for fast removal, 60 grit for general grinding and blending, and 80 grit when you want a smoother finish before painting or coating.
