Norton 21288 Flap Disc 4-1/2" 60 Grit Zirconia Alumina Type 29

The Norton 21288 Charger R822 flap disc delivers aggressive material removal and long-lasting performance for metalworking applications. This 4-1/2 inch diameter disc features premium zirconia alumina abrasive grain that stays sharp longer than standard aluminum oxide, making it ideal for grinding, blending, and finishing on steel, stainless steel, and other hard metals.

Key Features:

• Type 29 conical design provides optimal grinding angle for aggressive stock removal
• 60 grit zirconia alumina grain for fast cutting and extended disc life
• 4-1/2 inch diameter with 5/8-11 threaded arbor fits standard angle grinders
• Resin bond construction withstands high heat and demanding applications
• Self-sharpening grain continuously exposes fresh cutting points
• Flexible flap construction conforms to workpiece contours

The Type 29 conical shape positions the disc at the proper angle for maximum operator control and material removal rates. The self-sharpening zirconia alumina abrasive delivers consistent cutting performance throughout the life of the disc, reducing downtime for disc changes and improving productivity on heavy-duty grinding operations.
