4-1/2″x7/8″ Type 29 Flap Disc – Zirconia

4-1/2″ Zirconia Flap Disc – Type 29

The 4-1/2″ Zirconia Flap Disc – Type 29 is designed for aggressive grinding, blending, and weld removal applications. Constructed with premium zirconia grain abrasive flaps bonded to a durable fiberglass backing, this disc delivers fast cutting performance and extended service life compared to standard aluminum oxide flap discs.

The Type 29 angled flap design provides a higher angle of attack, making it ideal for heavy stock removal, edge grinding, and weld blending. Zirconia alumina grain is extremely tough and self-sharpening, allowing the disc to perform exceptionally well under heat and pressure while maintaining consistent cutting action.
