Product information
These auger bits from Stern Werkzeuge in Austria are excellently suited for use in a hand brace with their square shank.
Two cutting edges, along with the pilot drill whose threaded tip is matched to the diameter of the drill bit, ensure quick yet sensitive progress. The threaded tip provides self-feeding of the bit, making significant pressure during drilling unnecessary. To achieve a clean borehole, these bits feature two scoring spurs.
These bits allow for just as fast work as modern auger bits, which, however, cannot be used in a hand brace due to their hex shank. The flutes provide plenty of space for the unobstructed transport of material removed. Originally designed for softwood, our tests show they are suitable for all European woods, with pronounced upper arms proving beneficial especially with hardwoods as the diameter increases.
The dimensions of the tapered square can be used to determine the extent to which a bit is suitable for use in an existing hand brace. It usually bears the stamp of the metric diameter, and to some extent, the approximate imperial measurement.
This may be the last opportunity to acquire these virtually unique bits, as production has unfortunately been discontinued. Fortunately, we were able to secure the entire remaining stock. Storage marks in the form of superficial surface rust, which do not affect functionality, should be accepted. By clicking on the sample photos, the delivery condition can be easily assessed from the enlarged image.
Compatible with our hand braces 300228, 300229, 300224, 300225, and 301185, among others.
