A rotatable cutting tool includes a rotatable tool body and a replaceable cutting tip for chip removing machining. The tool body includes a forward free end having a first dovetail coupling part formed thereon. The cutting tip includes a front cutting end and a rear mounting end. The mounting end includes a second dovetail coupling part joined to the first dovetail coupling part. An actuator, such as a screw, is provided which is arranged for elastically deforming one of the dovetail coupling parts to create a tightly clamped relationship between the first and second dovetail coupling parts. Insertion of a replacement cutting tip is performed by laterally mating the dovetail coupling parts until one of the coupling parts abuts a laterally facing stop surface of the other coupling part.
A rotatable tool comprising a rotatable tool body and a replaceable cutting tip for chip removing machining, the tool body defining a longitudinal axis of rotation and including a forward free end having a first dovetail coupling part formed therein, the cutting tip including a front cutting end and a rear mounting end, the mounting end including a second dovetail coupling part joined to the first dovetail coupling part in tightly clamped relationship, the cutting tip being removable from the tool body by sliding the second dovetail clamping part out of engagement with the first dovetail clamping part in a direction laterally of the axis of rotation, wherein one of the dovetail coupling parts includes a laterally facing stop surface against which the other dovetail coupling part abuts, to limit the extent of insertion of the cutting tip onto the tool body.
The tool according to claim 10 wherein the first dovetail coupling part comprises a male part, and the second dovetail coupling part comprises a female part, the stop surface being formed in the female part.
A rotatable tool comprising a rotatable tool body and a replaceable cutting tip for chip removing machining, the tool body defining a longitudinal axis of rotation and including a forward free end having a first dovetail coupling part formed therein, the cutting tip including a front cutting end and a rear mounting end, the mounting end including a second dovetail coupling part joined to the first dovetail coupling part, a manual actuator arranged for releasably holding the first and second dovetail clamping parts in tightly clamped relationship with one another, the cutting tip being removable from the tool body by sliding the second dovetail clamping part out of engagement with the first dovetail clamping part in a direction laterally of the axis of rotation, upon release of the actuator.
A cutting tip for chip removing machining formed of a hard material, the tip defining a longitudinal axis of rotation and including a front cutting end and a rear mounting end, the rear mounting end including a female dovetail coupling part formed therein, the female dovetail coupling part extending laterally of the axis.
A method of replacing a spent cutting tip of a rotatable tool with an identical replacement cutting tip, the tool comprising a tool body defining a longitudinal axis of rotation and having a forward free end which includes a first dovetail coupling part, the spent cutting tip including a front cutting end and a rear attachment end including a second dovetail coupling part joined to the first dovetail coupling part in tightly clamped relationship with one another;
