Let's face it. When working around so much precious metal, some polishers are tempted supplement their income with your gold. Take away the temptation. The WhirlWind Grinding Hood, when used with a good dust collector (like the Super WhirlWind Jr.), makes losses a thing of the past. 100% thief-proof, grinding collection cannot be circumvented. The WhirlWind Grind Hood has a built in light and a special Plexiglas view plate. With a proven track record almost of almost 10 years, the WhirlWind Grinding Hood is time tested to be the most efficient grinding hood ever made. No other hood even comes close.
