4 1/2 x 5/8-11 Z3-40 Compact-Trim

Features

• Trimming the backing material allows more of the flap 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
• Active grinding agent provides cool cutting with light pressure
• Trimmable Z3 flap disc backing easily trims down to expose flaps for extended working life
• The trimmable backing allows for longer production times since wheels aren't changed as often
• Premium zirconia alumina grain with a poly cotton heat treated backing
• The poly cotton combination provides low stretch and strength for the high zirconia concentration that Z3 contains
• 20% more material than regular Z3 flap discs
• 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
• Recommended for aggressive use and heavy duty applications
