1,017,301. Tool holders. SOC. DES POUDRES METALLIQUES ET DES ALLIAGES SPECIAUX UGINE, CARBONE. Jan. 11, 1963 [Jan. 11, 1962], No. 1382/63. Heading B3B. A tool holder having means for clamping a chip-breaker in relation to the cutting edge of the tool comprises a body 1 recessed to carry a dispensible carbide tip 4 on a base member 2. A jaw 5 with a recessed port 6 houses a spring blade 7 which supports a projection 9a on a chip-breaker 9. The jaw is provided with a slot 11 through which passes a securing screw 12 for gripping and compressing the chip-breaker 9 and tool 4 between the jaw 5 and the base member 2. Adjustment of the chip-breaker 9 in relation to the cutting edge of the tool is effected by a grub-screw 14 located in an unthreaded bore 16 in the body 1. The rotation of the grub screw in relation to the threaded portion 5a of the jaw 5 permits the advance and withdrawal of the chip-breaker in relation to the tool without affecting the tool position relative to the work. The locking-screw 12 is released and retightened to facilitate this adjustment. |
