The Chip Muzzle can be trimmed for specific purposes. When working around asbestos coated pipes, it can be shaped into a concave shape or when working in corners it can be mitered for greater efficiency. When used with a standard industrial vacuum, it will collect up to 95% of the toxic dusts being removed. It comes with all the necessary attachments including a 3/4-in. step up hose for adapting to the standard 6-ft. by 1.25-in. by 2-in. hose.
