DRILLING DEBRIS RETENTION CONTAINER

摘要

The container comprises two sheets of thin material sealed along its edges. A double sided adhesive layer 2, affixed to its back forms an attachment of the container to the surface being drilled and a seal between the container and surface. A hole relative to size of hole being drilled passes through all three layers. The hole is centred over the spot to be drilled to allow the bit to pass through the container. During the drilling process debris is extruded from the material being drilled into the container. A strip of containers may be provided, each removable from the next by perforations.
