In a device for fixing and clamping a workpiece, comprising:
- an elongated housing having a central bore with a longitudinal central axis, and including a frontal portion having a radial collar and a rearwardly tapered frontal face which opposes said workpiece and extends to an outer circumferential surface of said collar;
- a longitudinally displaceable centering mandrel located within said bore and displaceable between an extended position, wherein a first end of said mandrel extends beyond said frontal face, and a retracted position, wherein said first end of said mandrel is positioned behind said frontal face;
- and
- means for moving said mandrel between said retracted and extended positions;
- the improvement wherein said frontal portion of said body includes:
- a cut back portion recessed rearwardly from said frontal face and providing an opening which extends from said outer circumferential surface of said collar to said longitudinal axis, and at least around a portion of said circumference, whereby
- in use, the workpiece is inserted from the direction of the remaining non-cut back portion of said frontal portion.
