Abstract

A tool for material-removing machining of workpieces of hard metal with a blade plate held by a clamping lug is suggested which is distinguished in that the blade plate (11) has a groove (25) provided on the front side (45) in which the clamping lug (13) engages.

Claims

1. Tool for material-removing machining of workpieces of hard metal, with a blade plate held by a clamping lug, characterized in that the blade plate (11) has a groove (25) provided on the front side (45) in which the clamping lug engages.

2. Tool according to claim 1 characterized in that the blade plate (11)-viewed from above-is configured essentially as a triangle.

3. Tool according to claim 1 or 2 characterized in that the groove (25) in cross section has an edge which encloses an angle of approximately 8°

to approximately 12°

, preferably approximately 10°

with the front side (45) of blade plate (11).

4. Tool according to one of the preceding claims characterized in that the groove (36) extends practically over the entire width of the blade plate (11).

5. Tool according to one of the preceding claims characterized in that the clamping lug (13) has a clamping lip (23) the width of which corresponds to about the length of the groove (25) and preferably lies within the incircle of blade plate (11).

6. Tool according to one of the preceding claims characterized in that the clamping lug (13) is configured as a prism.

7. Tool according to one of the preceding claims characterized in that the base body (3) of the tool (1) in the area of the blade plate (11) has a projection which serves as a support (39).

8. Tool according to one of the preceding claims characterized in that the base body (3) of the tool (1) is configured as one piece.
