Autolock collets require cutters with threaded shank ends to screw into the collet itself. Threaded fasteners either have a tapered shank or a non-tapered shank. An HSK toolholder has both a tapered shank, and a flange with a mating surface. It could be fitted on either a tapered or non-tapered shank. Jig hooks are designed to have lead weight molded onto the hook shank. A rotary hammer uses SDS or Spline Shank bits. Care must be taken to ensure the bit shank and router collet sizes match exactly. It is a traditional accompaniment to the Milanese braised veal shank dish "ossobuco alla milanese". Ring contacts are typically the same diameter as the sleeve, the long shank. HSK stands for ; German for "hollow shank tapers". Hook points are also described relative to their offset from the hook shank. Some installer bits have a transverse hole drilled at the shank end as well. Punches are made in straight shank or ring shank, the latter used to mark rings. The hammer of the drill hits the flat end of the shank. End mills are sold in both imperial and metric shank and cutting diameters.
