A tool holder (10) comprising a shank portion (12), a tool mounting portion (14) and a circular flange portion (16). Disposed in the mounting portion is a central aperture (20) while disposed in the shank portion is a threaded aperture (22) which communicates with the central aperture. The tool holder further comprises a cylindrical sleeve member (24) receivable into the central aperture via thermal contraction. A tool mounting aperture (30) extends through the sleeve member. The shank portion (32) of a cutting tool (34) is receivable into the mounting aperture via thermal contraction. Disposed in the inner surface of the mounting aperture is at least one channel (40) for forming a coolant fluid passage between the tool holder (10) and the cutting tool (34). |
