A plug cutter is a tool used to cut wooden dowels for repairing imperfections or damage in wooden objects. The dowels produced have a chamfered edge and are tapered for a secure fit, making them superior to wood putty. Cork cutters are used to cut circular grooves in wood, which are then snapped or cut into fill plugs. Using dowels from the same wood as the construction allows for a color and grain match that makes repairs difficult to detect. Cutters are made from high carbon steel and come in sets of different sizes for hard and soft wood.
A plug cutter is a woodworking or joinery tool used to cut wooden dowels for use as filler pieces to repair imperfections or damage in wooden objects where the use of wood filler is not desirable. Such tools are manufactured for use in a hand drill or drill press and have cutting edges designed for hard or soft wood. The dowels produced by a cork cutter have a chamfered or chamfered edge for easy insertion and are tapered to ensure a secure fit, making them a superior option to using wood putty. Cutters can be re-sharpened and typically come in sets of different sizes for both hard and soft wood.
A cork cutter is a hollow tubular tool with a cutting edge machined into one end and a mandrel or shaft on the other. The arbor is inserted into the chuck of an electric hand drill or drill press and the tool used to cut a circular groove in the wood. The center “pillar” within the groove is then snapped or cut and used as a fill plug. The internal profile of the cork cutter is such that the plugs are slightly tapered with a bevelled edge. These plugs are coated with wood glue and pushed into place in the hole to be filled.
The use of screws, nails and other metal fasteners in wood furniture construction is a strong and durable option, but leaves behind aesthetic aberrations that are often difficult to disguise. The same goes for knots and other natural imperfections. Wood filler can also be a quick and easy fix for masking or filling unwanted holes, but it has several drawbacks such as shrinkage and cracking.
A cork cutter to produce filler plugs can be a far better option and allows for long-lasting, nearly invisible repairs. When building new wooden elements, the dowels can be cut from the same wood used for the construction; this allows for a color and grain match that makes the repair job very difficult to detect. Wood dowels also expand and contract with the rest of the piece and therefore do not crack or fall off over time as is the case with wood filler.
Cutters are usually made from 62c high carbon steel and can be sharp when dull. Some cork cutter models incorporate an automatic plug ejection system, although most are based on the plug being manually removed with a screwdriver or cut with a saw. Since cork cutters do not have a center guide or spur, the most accurate and consistent results will be obtained using a drill press. Dowel bits are usually purchased in sets that include bits of various sizes suitable for both hard and soft wood types.
