125 MM X 22 MM 3M™ VARIOUS GRITS (CF 10 PCS) 566A FLAT FLAP DISCS

3M™ 566A Flat Flap Discs – Ø 125 mm x 22 mm (Type 27)

The 3M™ 566A model represents a versatile and economical solution for metal fabrication applications requiring high removal rates and a consistent finish in short times.

Advantages and Technical Features

• Alumina-Zirconia (AZ) Abrasive: This synthetic mineral self-fractures during use, continuously generating new, sharp cutting edges. Compared to aluminum oxide, it ensures a higher cutting speed and significantly longer blade life.
• Heavy Duty Backing: The cotton-polyester canvas backing (Y/YF weight) is designed to withstand medium to high pressure, ideal for treating sharp edges without the risk of premature fraying.
• Flat Design (Type 27): The flat shape is optimized for machining large, flat surfaces, offering superior control and a smooth finish without unwanted grooves.
• Resin Bond: Designed to withstand the high temperatures developed during grinding, preventing bond deterioration and maintaining the integrity of the disc even under intensive use.
• Superior Finish: Under standard conditions, 566A flap discs produce a one degree finer finish than fiber discs of the same grit, reducing the need for subsequent finishing steps.
