ABSTRACT:
A tool for chip removing machining, including a replaceable cutting insert and a basic body. The basic body includes a rear fixing part, a front supporting part having an insert seat, and a tightening part situated over the support part, and spaced-apart from the front supporting part by a first gap and from the rear fixing part by a second gap. The tightening part is connected to the basic body via a joint. The joint is formed of at least one elastically resilient material portion and has an axis around which the tightening part is pivoted in order to press the cutting insert against the insert seat by a front finger. The rear fixing part includes an internal channel for feed of a fluid in the forward direction through the basic body. The internal channel extends into a second channel inside the tightening part via a channel section that is entirely or partly housed in a bridge which, like the joint, is formed of the material in the basic body, and which bridges one of the first and second gaps.
