The BON TOOL 66-327 is a square finish trowel designed for professional concrete and plaster finishing work. Built to the Steel City standard, this trowel features a blade measuring 20 inches in length by 4 inches in width with square corners, making it well suited for tight edges, corners, and broad flat surface finishing passes. The wood handle provides a traditional grip preferred by many journeymen finishers. At 2 pounds, the tool balances blade coverage with manageable weight during extended finishing work. Licensed tradespeople in masonry, plastering, and flatwork concrete finishing are the primary users of this tool.
This finish trowel is used in residential and commercial flatwork, wall plaster, stucco finish coats, and overlay applications where a square blade profile is required. The 20 x 4 inch blade size suits both broad surface passes and detail work along formed edges. It is a standard production tool carried by concrete finishers, plasterers, and masons working on slab, wall, and decorative surface finishing projects.
Designed as an OEM-style professional finish trowel suitable for concrete flatwork, plaster, stucco, and overlay finishing applications requiring a square-end blade.
This tool is used by licensed concrete finishers, plasterers, and masons. No power source or mechanical connection is required. Rinse the blade thoroughly after each use to prevent cement or plaster buildup, which can pit the blade surface and reduce finish quality. Store dry to prevent rust on the steel blade.
