Designed to be used with either a power drill or with an adapter in a traditional hand brace, these Japanese High Carbon Steel combination auger bits from Star-M are first-rate. They have a lead screw and a rounded single spur to ensure that the edge of the hole is perfectly clean and tidy while removing the excess wood so eliminating clogging.
Made for softwood and less dense hardwoods.
