If you’re grinding, blending, or polishing pipes, tubing, or other compact, irregular surfaces, the 3” x 1” x 1/4” Mounted Flap Wheel with shank by Black Hawk Abrasives is the abrasive you need! Made with premium aluminum oxide coated, x-weight cloth flaps arranged in a circular fan shape around the center straight shank, these wheels are built to last and provide an extra element of flexibility. As the flapper wheel is used the flaps wear down, exposing new sharp abrasive material which extends the life of the tool and provides a consistent cut. Moreover, the fan shape of these 3 inch flap wheels allows for added flexibility which makes them ideal of irregular shaped work pieces especially work within cylindrical pieces like pipes and tubes. 3 Inch x 1 Inch x 1/4 Inch Shank 80 Grit, Aluminum Oxide Coated Flaps Great on non-ferrous and ferrous metals 9,500 Max RPM Pack of 5 UPC 742889950914 ASIN B077GDXGRB Model IL-5R0T-AOO5 Grit Type Medium Brand Name BHA Unit Count 5.0 Count Grit Number 80 Item Weight 1 Pounds Part Number IL-5R0T-AOO5 Manufacturer BHA Item Diameter 3 Inches Material Type Aluminum Oxide Item Thickness 0.25 Inches Item Dimensions 6 x 3 x 5 inches Number of Items 5 Construction Type Coated Compatible Devices Angle Grinder, Bench Grinder, Die Grinder Grit Material Type Aluminum Oxide Compatible Material Metal Item Dimensions L x W 3 L x 3 W Maximum Rotational Speed 9500 RPM Recommended Uses For Product Polishing
