Ring Auger Bits
Ring Auger Bit - Made in Japan
The rounded single spur of these bits cut a clean edge of the hole and the chisel-like cutting edge turns around the threaded center and removes chip by chip within the previously cut circle. The thread of the center is large and strong enough to bite into the wood and pulls the bit. You do not have to use any pressure. This bit with large threaded center is unsuitable for power drills. For softwood and European hardwoods such as oak, beech, cherry. All measurements in mm, imperial only approximately!

Ring Auger Bits from old stock
These bits have been stocked for several years and have not been used. They come in best condition. Please pay attention to the notes, some have a thicker shaft than the spiral and some do not have edge spurs. If there is no note, they come with two edge spurs. Some spurs have small burrs which must be removed with a file (only from inside please!)
Only to be turned by hand! Enlargement - see also the bits without spurs and the bits with thicker shaft.
