Abstract
A rotary chip-removing tool includes a rotary tool body and a tool tip fastened on a front end thereof. The tool tip is formed of an injection molded body which has an integral cutting edge at its front end, and a coupling structure at its rear end. The coupling structure can be in the form of a threaded hole, or a rearward projection, for coupling the tool tip against the tool body. The tool tip is formed of first and second materials. The first material forms at least part of the cutting edge, and the second material forms the coupling structure. The first material is more brittle than the second material, and the second material is tougher than the first material.
Claims17
A rotary chip-removing tool, comprising:
- a tool tip including a body having a front end forming an integral cutting edge, and a rear end forming a support surface having a first coupling structure;
- a rotary tool body defining an axis of rotation, with a second coupling structure disposed at a front end of the tool body in engagement with the first coupling structure for fastening the rear end of the tool tip against the front end of the tool body;
- a first portion of the tool tip possessing at least part of the cutting edge and formed of a first material, and a second portion of the tool tip possessing the first coupling structure and formed of a second material, the first material being more brittle than the second material;
- and the second material being tougher than the first material.
A tool tip for rotary chip removal, comprising an injection molded body defining a central axis of rotation and including front and rear ends, the front end forming an integral cutting edge, the rear end including a coupling structure adapted to couple the tool tip to a tool body, a first portion of the body possessing at least part of the cutting edge and formed of a first material, and a second portion of the body possessing the coupling structure and formed of a second material, the first material being more brittle than the second material, and the second material being tougher than the first material.
