Features

• Trimming the backing allows for more of the disc to be used for fewer disc changes and better production rates
• Simply angle the backing edge against a hard metal to expose more flap material
• Stiff backing construction paired with a compacted 4 deg flap angle make grinding easier, quieter and with less vibration
• Ceramic flap discs are designed to last longer than zirconia flap discs
• Polyester backing material for longer life
• To trim down the backing simply grind the backing edge against a metal edge until the flaps are exposed to the level needed
• Flaps are compressed at a 4 deg angle for flap edge strength
• Best used at 5 to 20 deg angle
