Abstract

A cutting tool is provided with cutting elements being arranged in continuously recurrent groups comprising three or four cutting elements. These cutting elements are arranged in different distances (A, B, C, D, E, F, G) to each other which distances shall be within certain determined limits.

Claims

1. A cutting tool having cutting elements arranged in recurrent groups of three elements, a first pair of adjacent elements in a group spaced from one another by a first distance;

a second pair of adjacent elements in said group spaced from one another by a second distance;

the trailing element of said group being spaced from a leading element of a subsequent group by a third distance;

said first, second and third distances being all different from each other and each being expressed as a percentage of a period length of said group wherein one of said distances lies within the range of from 17 to 28.5 percent, another of said distances lies within the range of from 28 to 36 percent, and the remaining one of said distances lies within the range of from 40.5 to 50 percent.

2. A cutting tool according to claim 1, wherein said one distance lies within a range of from 22.5 to 28.5 percent;

said another distance lies within a range from 28 to 34 percent; and

said remaining distance lies within a range of from 40.5 to 46.5 percent, the order of said distances being consistent among all groups.

3. A cutting tool according to claim 2, wherein said one distance comprises 25.5 percent;

said another distance comprises 31 percent; and

said remaining distance comprises 43.5 percent.

4. A cutting tool according to claim 1, wherein said one distance lies within a range of from 17 to 23 percent;

said another distance lies within a range of from 30 to 36 percent; and

said remaining distance lies within a range of from 44 to 50 percent, the order of said distances being consistent among all groups.

5. A cutting tool according to claim 4, wherein said one distance comprises 20 percent;

said another distance comprises 33 percent; and

said remaining distance comprises 47 percent.
