Embodiment Construction
[0011] The jaw 10 according to the invention in the figures comprises a steel base body 12 which is substantially cylindrical. Rack-like teeth 14 are provided laterally along part of the length of the jaws 10 in order to move the jaws 10, for example when clamping a drill in a drill chuck (jaw chuck). The teeth 14 are indicated by dotted lines in the figure. On the side opposite to the face where the tooth 14 is located, the jaw 10 ends with a bevel 16 . The clamping face 18 of the jaw is formed by providing a longitudinal groove 20 on the inclined surface 16 of the base 12 of the jaw 10, into which hard metal particles 22 are embedded and joined to the base by brazing. The hard metal particles 22 include angular hard metal particles that form the clamping surface 18 . If the setting of the hard metal particles 22 is not so precise after brazing, the hard metal particles 22 can be machined into shape by grinding after brazing.
