Irwin Industrial Tool Co 43906 Plug Cutter 3/8 Inch

Product Description

The IRWIN INDUSTRIAL TOOL CO 43906 is a plug cutter designed for covering fastener holes in wood surfaces. It accepts a 1/4 inch shank and cuts plugs 3/8 inch in diameter. Constructed from hardened, high carbon steel, it delivers the strength and edge retention needed for consistent cuts in hardwood and softwood alike. Woodworkers, cabinet installers, flooring crews, and deck builders reach for this tool when a clean, finished look is required over countersunk screws and bolts. It can also be used to produce short wood dowels for joinery work.

This plug cutter is suited for residential and light commercial woodworking applications. Typical uses include concealing fastener heads in furniture construction, cabinetry installation, hardwood flooring, and exterior deck boards. The 3/8 inch cut diameter is a common standard size for wood plug stock, making it straightforward to source or mill matching plugs from the same species as the workpiece. It is intended for use in a drill press or handheld power drill.

Installation Notes

Installation is performed by woodworking professionals or skilled tradespeople using a drill press or power drill. Secure the workpiece firmly before cutting to prevent movement and ensure a clean plug. Run the cutter at an appropriate RPM for the wood species being worked — harder woods generally require slower speeds. Always wear eye protection when operating rotary cutting tools.
