PFERD Type 29 Aluminum Oxide Flap Disc | 7/8" Arbor Hole | 62231 | 4-1/2" Diameter (Box of 10)

This unique flap disc offers very cool grinding on materials with poor thermal conductivity. Excels at grinding applications which require high-grade surface finish and low thermal stress. It also resists loading, making it equally useful on aluminum and non-ferrous metals.

Features:

• Diameter: 4-1/2"
• Hole Size: 7/8"
• Grit: 40
• Max RPM: 13,300
• Abrasive: Aluminum Oxide Plus Coolant
• INOX-rated: Free of iron, sulfur and chlorinated fillers; suitable for use on stainless steel (INOX)
• Workpiece Materials: Stainless steel (INOX), aluminum, non-ferrous metals
• Application: Weld removal, surface grinding with low heat input
• Recommendation for Use: Ensures low build-up of heat in the workpiece when used with minimum contact pressure. Performs exceptionally well on sheet metal and thin sectional material.
