Flexovit® ZIRCOTEX® Z4503FH 4-1/2" x 5/8"-11 36 Grit Type 29 Spin-on Flap Disc
Aggressive Grinding Power with Fast, Tool-Free Disc Changes
The Flexovit® ZIRCOTEX® Z4503FH 4-1/2" x 5/8"-11 36 Grit Type 29 Spin-on Flap Disc is engineered for heavy-duty grinding applications where fast stock removal, durability, and quick-change convenience are essential. Built with high-performance zirconia alumina abrasive grains, this flap disc delivers aggressive cutting action and long service life across demanding industrial environments.
Type 29 Angled Design for Maximum Grinding Efficiency
Enhanced Contact for Faster, Smoother Results
Featuring a Type 29 conical profile, the Z4503FH excels when grinding at steeper angles, providing greater surface contact for rapid material removal. This design is ideal for:
-
Heavy weld grinding
-
Beveling and edge chamfering
-
Deburring and surface leveling
-
Preparing metal prior to fabrication or finishing
The angled flap layout makes blending and contour grinding smoother and more controlled, even on uneven workpieces.
36 Grit Zirconia Alumina for Aggressive Stock Removal
Self-Sharpening Abrasive for Consistent Performance
The 36 grit zirconia alumina grain provides powerful cutting performance well-suited for carbon steel, stainless steel, alloy steels, and tough ferrous materials. Zirconia’s self-sharpening characteristics continually expose fresh cutting edges, ensuring the disc maintains its aggressiveness throughout its life while reducing downtime and replacement cost.
Spin-on Hub for Tool-Free Productivity
Quick, Secure Disc Changes
Equipped with a 5/8"-11 spin-on threaded hub, the Z4503FH enables fast, tool-free installation and removal—ideal for high-production shops and field operations where efficiency matters. This convenience boosts workflow and minimizes interruptions during grinding tasks.
Built for Industrial Durability
A reinforced fiberglass backing provides strength, reduces vibration, and enhances operator comfort during extended use. The 4-1/2" size fits standard spin-on grinders used across fabrication, shipbuilding, automotive repair, pipeline work, and heavy equipment maintenance.
Proudly designed as part of the Flexovit® ZIRCOTEX® series, the Z4503FH delivers the rugged performance, quick-change convenience, and long-lasting durability that professionals depend on.
