CRATEX
Cratex wheels are available in diameters from 1/2" to 6"
Dimensions shown are Diameter x Thickness x Arbor hole
Cratex wheels are available in four rubber bond compositions that differ with the mesh size of the silicon carbide abrasive grain:
Coarse (Dark Green)
Medium (Dark Brown)
Fine (Reddish Brown)
Extra Fine (Light Green)
Rubberized abrasives are a good choice for removing rust, heat marks, tarnish, excess solder, scratches, and corrosion.
Use Cratex for blending and polishing welded seams after rough grinding, polishing bearing surfaces and raceways, removing burrs, breaking edges, smoothing and polishing castings and punched or sheared pieces, wet sanding of gem castings, wet sanding of gem stones, trimming plastic articles, smoothing glass edges, cleaning before welding or soldering, and other deburring, smoothing, and polishing operations.
Maximum safe speeds:
1/2" - 7/8" diameter … 24,000 RPM
1-1/2" diameter …….. 15,000 RPM
2" diameter …………. 10,500 RPM
2-1/2" diameter ………. 8,300 RPM
3" diameter …………… 7,000 RPM
4" diameter ………….... 5,250 RPM
5" diameter …………… 4,200 RPM
6" diameter …………… 3,600 RPM
Best results are generally obtained at 30% - 80% of the maximum safe speeds, and with light work pressure. Do not exceed the maximum safe operating speed.
ALWAYS WEAR EYE PROTECTION WHEN USING CRATEX WHEELS
