Standard Abrasives™ Zirconia HP Type 27 Flap Disc 645929, 4-1/2 in x 7/8 in 60, 10/CA

Designed for rapid high pressure grinding, our Standard Abrasives™ Zirconia HP Flap Disc features extra-sharp alumina zirconia mineral on hard-wearing polyester flaps. The overlapping flaps provide extended durability and progressively reveal fresh zirconia alumina mineral for continuous sharp cut as the flaps wear away, making this a great solution for beveling, deburring, and edge chamfering.

• Flaps offer single-step grinding and blending and may replace grinding wheels and fiber discs
• Durable flaps hold up in tough applications to maximize disc life
• Zirconia HP material offers excellent versatile performance on many different applications requiring low to medium pressure
• Grinding aid keeps the disc running cool on stainless and heat-sensitive alloys
• Overlapping layers extend durability for prolonged use in industrial operations
• Poly-cotton backing resists edge tearing or fraying under high pressure
• Phenolic resin plate provides cushion effect for optimal blending and dampens vibration, reducing operator fatigue and tool wear
