Sometimes when plugging holes, no matter how carefully drilled, the holes finish up slightly oversize for the plug, especially in soft woods. These cabinet makes snug plug cutters overcome this by cutting a slightly tapered plug. The first 3mm of the plug is the diameter stated whilst the remaining length is then flared out at an angle of 3 degrees. Just tap the plug into place until you meet resistance then cut off the excess. Also, unlike regular plug cutters which have two cutting flutes, these plug cutters have four, giving a much cleaner cut and a smooth-sided plug which fits perfectly every time and is practically invisible. For best results use in a drill press or power drill stand. Also available with matching TCT lip and spur drill.
