Norton Type 27 Flat 4-1/2-Inch Flap Disc

Norton Type 27 Flat 4-1/2-Inch Flap Disc

Norton flap discs are versatile grinding and finishing tools having four main components: abrasive flaps, flap density (how the flaps are stacked), backing plate shape (flat or conical), and backing plate material (fiberglass or plastic). All flap discs have flaps that are overlapped and glued to the backing plate. The flaps wear during use, exposing new abrasive grain. The different variations of the components above provide a variety of application choices ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can be preferred over depressed center wheels or fiber discs.

Features:

• Durable zirconia grain provides a good cut rate and life with a consistent finish
• Fiberglass/resin backing plates with high strength, lightweight, ability to absorb vibration, and operator comfort
