Flexovit® Alushark™ Z4328FH 4-1/2" x 7/8" A36 Type 27 Spin-On Flap Disc
Aggressive Aluminum Grinding with Quick-Change Convenience
The Flexovit® Alushark™ Z4328FH 4-1/2" x 7/8" A36 Type 27 Spin-On Flap Disc is engineered for high-efficiency grinding on aluminum and other non-ferrous metals—materials where traditional abrasives often clog, glaze, and lose cutting power. Featuring Flexovit’s advanced Alushark™ technology, this flap disc resists loading and delivers cooler, cleaner, and faster grinding, making it the ideal choice for professionals who demand consistent performance.
Type 27 Flat Profile for Smooth, Controlled Grinding
Ideal for Shallow-Angle Applications
Built with a Type 27 flat configuration, the Z4328FH excels at shallow-angle grinding, offering excellent operator control on flat or slightly contoured surfaces. It is perfect for:
-
Heavy stock removal
-
Weld grinding and cleanup
-
Edge chamfering and beveling
-
Leveling castings and repairing aluminum components
The flat profile ensures even contact and smoother finishes, reducing the risk of gouging softer metals.
A36 Aluminum Oxide Grain for Fast, Aggressive Cutting
Designed for Non-Ferrous Metals
The 36-grit aluminum oxide abrasive provides strong, aggressive cutting action ideal for heavy surface preparation. Alushark™ technology prevents clogging—one of the most common issues when grinding aluminum—allowing the abrasive grain to stay sharp and effective throughout extended use. This results in improved productivity, longer disc life, and superior surface consistency.
Spin-On Hub for Tool-Free Disc Changes
Maximize Productivity in Busy Shops
The Z4328FH features a spin-on hub, enabling fast, secure, wrench-free disc changes. This is especially valuable in high-volume fabrication shops where minimizing downtime is critical. With its 4-1/2" diameter and 7/8" spin-on attachment, it fits most spin-on angle grinders used in welding, fabrication, and maintenance operations.
Built for Industrial Performance
A reinforced fiberglass backing delivers strength, stability, and reduced vibration for a safer, more comfortable grinding experience. The Z4328FH is trusted across industries including automotive, aerospace, marine construction, aluminum fabrication, and trailer manufacturing.
Backed by Flexovit’s commitment to advanced abrasive engineering, the Z4328FH Alushark™ Type 27 Spin-On Flap Disc provides unmatched grinding efficiency, long service life, and industry-leading performance for non-ferrous metalworking.
