A procedure for attaching the handle of a screwdriver to its metal shank (3), consists of: (1) positioning the shank and an external grip (8) in a mould (16); and (2) filling the cavity with a plastic material (7). The procedure, especially for attaching the handle of a screwdriver to its metal shank (3), consists of positioning the shank and an external grip (8) in a mould (16) so that a cavity (20) is left between them. The cavity is filled with a plastic material (7), injected through at least one inner point (19) of the cavity in a radial direction relative to the handle's outer surface and in advance of the cavity's rear end. The injection point, accessed through a radial channel (18) in the mould, is located behind the rear end of the metal shank (3), and the plastic is injected in the direction of the shank. The mould is in two halves (16A, 16b) meeting along a parting plane (P), with a hole at one end to support the shank. |
