The Dust Muzzle

The Dust Muzzle is a scientifically designed dust collection shroud made of transparent polypropylene that uses the centrifugal forces generated by the angle sander to remove dust and pollutants from the workplace.
Because the centrifugal forces of the sander push the dust out the exhaust nozzle of the Dust Muzzle, only a small vacuum is needed to further remove the dust to a canister or a central collection point.
The Dust Muzzle is flexible. The built in corrugations allow the operator to manipulate the tool much the same as if no Dust Muzzle were attached.
The Dust Muzzle is transparent. It is made of clear polypropylene that allows the operator to see his work and grind to within . 125" of any vertical surface.
The Dust Muzzle is over 95% efficient. Test done by users have shown that virtually all the fine pollutants can be removed at the point of origin when the Dust Muzzle is used properly.
The Dust Muzzle increases abrasive life by over 500%. During normal sanding operations, the sanded particles clog up the surface of the paper. The Dust Muzzle removes these particles from the workplace and allows the paper to remain clean and unclogged.

The Dust Muzzle retrofits easily. The Dust Muzzle attaches with a standard hose clamp to over 1200 models of die grinders, angle sanders and RO/DA sanders. After adjusting the collar height to fit your back up pad, the Dust Muzzle is slipped over the bearing housing of the sander and secured with a hose clamp. The entire installation takes less than five minutes!
Unlike many dust collection systems, the Dust Muzzle requires no special sandpaper or back up pads.
The Dust Muzzle is efficient on a variety of surfaces. Each Dust Muzzle comes with vacuum relief holes which allow the operator to vary the amount of vacuum applied to the work. On very smooth surfaces, the vacuum punch outs are removed, allowing a smooth air flow through the shroud. On rough or curved surfaces, the plugs are left intact, allowing the vacuum to be drawn from the sides of the Dust Muzzle.
If the operator changes from smooth to rough surfaces, he can simply tape over the holes as needed to achieve the vacuum draw he requires.
CAUTION: When sanding any material that could produce a spark, be sure your vacuum collection bag contains no flammable materials. Do not use the Dust Muzzle with a hard grinding wheel. The Dust Muzzle is not to be used as a replacement for a scatter shield.

Have any of you evre use the dust muzzle? what do you all think of it? Do you think it would work jus as good with a smaller pad and water.

	Abrasive Abrasive: There are two types of abrasives, loose and bonded. Loose abrasives can be used to hone any de-lipped surface and should not be used on any uneven surface. Loose abrasives will not work well in moderate to heavy traffic areas. They work great on counter tops. Loose abrasives are sold in a powder form. Bonded abrasives can be used to remove lips from the surface. Choosing the correct bond is very important. They are sold in metal, copper, and resin bond. To remove lippage the metal will work best. But they are very aggressive. Copper will work on lippage but it will take about 25% more time to complete the same task. If the surface was already de-lipped the copper will remove deep scratches from the surface. Resin is the least aggressive of the bonded abrasives. Resin bonds won’t remove lips. However, they work well on light traffic areas.

	grinding This is the second stage in securing a flawless surface. This stage will remove all scratches from any de-lipped surface.

I bought one of these for Metabo. It doesn't even come close to being able to fit on the machine. Worst part about it is I was in a Specialty Tool Store, and the salesman sold me both items. When I finally needed the use of this thing (remodel job), I couldn't use it. Good idea, but very disappointed that it didn't work for my Metabo.

John,

I suspected that would be a problem too but didn't want to mention it at first - no 2 angle grinders are alike at the nose. I have tried to change guards from one to another in the past usually with no luck. You would think they would have to build one for each manufacturer.
