Medium Grit, Medium Hardness, A-5588 Coarse Grit, Hard Hardness
3M Scotch-Brite EXL Unitized Wheel, 3″ dia, 1/2″ thick, 1/4″ arbor hole. Made with Aluminum Oxide grain, Medium and Coarse Gits, and Medium/Hard (density/hardness rating of 6 on scale of 2 to 8 from soft to hard). Made in USA. See speed rating below.
Use on Foredom M. BL Bench Lathe. Mount directly onto tapered spindle or use A-WM-5 or A-WM-6 Wheel Mandrel.
EXL Unitized Wheels are ideal for light deburring, oxide and fire-scale
removal, cleaning, blending, and decorative finishing. They are made of
non-woven fiber, coated with aluminum oxide or silicon carbide abrasive
in fine, medium, or coarse grades. They run cool and should only be
used dry. They are defined by abrasive material, grade, and density or
hardness. Softer densities are best for decorative finishing as they
conform more readily to contour surfaces and create a more uniform
finish. Harder wheels are better for more difficult blending, surface
cleaning, and deburring.
Recommended working speeds vary depending on the desired finish and type
of metal. Slow speeds of 500 3,000 sfpm are best for softer metals
and composites while higher speeds of 3,700 8,500 sfpm work better
for harder metals. Certain speeds produce better results for specific
types of operations such as high speed for blending surface
3″ wheels can be mounted directly on to the spindles of Foredom’s M.BL Bench Lathe or with A-WM-5 and A-WM-6 wheel mandrels.
