Understanding & Choosing the Right Flap Disc

What is a Flap Disc?

Flap Discs are designed to increase work productivity and reduce overall cost by grinding, blending and finishing in 1 step. Flap Discs are constructed by layering coated abrasive flaps so when a flap wears away, a new flap will be expose with fresh, sharp abrasive grains.

Flap Disc Basics

There are 4 basics components of a flap disc: Backing Shape, Backing Type, Gain Type & Density.

Backing Shape

Type 29 – Conical Shapeflap-conical-300x71

  • Built-in angle for increased contact area
  • Best for use on contoured surfaces and edge work
  • Minimizes workpiece gouging
  • More aggressive stock removal due to higher angle
  • 15°-25° working angle

Type 27 – Flat Shapeflap-flat

  • Best for use on miter joints, corners and edges
  • Best choice for finishing intricate and ornate surfaces
  • Ideal for smooth finishing
  • 0°-15° working angle

Backing Type

Fiberglass Backingfiberglass-backing

  • Backing will wear uniformly with abrasive cloth
  • Will not splinter or smear on the workpiece
  • Lighter, quieter operation

Plastic Backing

  • Non-scratching, high strength backing
  • Resistant to temperature extremes, common chemicals and solvents
  • Some plastic backings are trimmable

Flap Backing: Polyester, Polyester-Cotton or Cotton

  • Polyester
    • Able to withstand extremely high pressure without degrading the flap
    • For extreme stock removal and edge grinding
  • Cotton
    • Used where maximum conformability and soft feel is the goalplastic-backing
    • Must be used under lighter pressure to maximize performance and life
  • Polyester/Cotton Blend
    • The best of both worlds
    • Can withstand high pressure while still maintaining good stock removal and finishing
    • Often used as the starting point for flap disc operations for first time users

Grain Type

Ceramic

  • This allows for a consistent under a wide variety of grinding applications
  • You should consider opting for a ceramic disc when grinding on steel, stainless steel or aluminum
  • Ceramics also tend to grind cooler minimizing discoloration while maximizing product life

Zirconium

  • These discs are used for general steel grinding, stock removal and finishingflap-regular
  • The economical choice when cost is the driving factor

Density

High density flap discs provide the user with approximately 40% more grinding material. This increase in grinding material leads to increased flap-highproductivity and longer life.

Choose Flap Disc Over..

Flap Discs Over Grinding Wheels

  • Quieter operation and reduced vibration minimizing operator fatigue
  • Cooler cutting, reduced loading and glazingflap-discs
  • Easy to use – reduced gouging and rework
