Technical Field

The utility model relates to a rock wool circle hole cutting means.

Background

Rock wool is a novel heat-insulating, fireproof and sound-insulating material and is widely used in the positions of modern building outer walls, roofs, industrial equipment, pipelines, kilns and the like. Rock wool often meets in the installation of rock wool various objects that pass through rock wool itself, square and circular wherein are many, but square cutting is comparatively simple, to opening out circular hole on the rock wool board, and complete circular hole can not cut out to general cutter.

At present, the radian of rock wool corners is cut by a cutter mostly when round holes are formed in rock wool, and then the rock wool corners are spliced at the protruded parts. Or the rock wool is dug out of the hole by a cutter, dust is generated in the cutting process by the method, and the hole is rough and uneven in joint after installation, so that the subsequent construction is influenced.
