Abstract: A tool for sampling building materials for the suspected presence of asbestos fibers. An annular (tubular) cutter element is rotated to remove a plug-like sample from a wall under study. A shroud-like canister surrounds the cutter element to trap any asbestos fiber particulates that might otherwise escape into the atmosphere. Closure caps can be applied to the canister, whereby the canister can be used to ship (transport) the sample to a laboratory for analysis.
