Equipped with an integrated wheel hub, these flap discs allow quick installation and removal without additional tools. The reinforced plastic backing improves disc stability and enhances safety during continuous grinding.

💎 High-Density Zirconia Abrasive – Smooth & Durable

Manufactured with premium high-density zirconia, these 4.5-inch flap discs provide consistent cutting performance, excellent heat resistance, and extended disc life, even during long grinding sessions.

⚙️ Type 27 Angled Profile – Precision Control

The Type 27 angled design supports a 5–15° working angle, making it easier to handle edges, corners, contours, and uneven surfaces. Fully compatible with standard 4-1/2" angle grinders with 7/8" arbor.
