Abstract
Abstract A cutting tool made up of a plurality of inserts. Each insert is in the form of a circular disk or cylinder having a plurality of cutting teeth disposed symmetrically around the outer periphery. The cutting members are adjusted in the holder so that each tooth progressively cuts behind the tooth ahead of it so that the peaks of one edge cover a part of the trough of another edge whereby said cutters progressively cut an article. The cutters can be adjusted so that as certain teeth wear, the cutters can be rotated to bring additional new teeth into cutting position.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
123 words
A rotary cutting tool comprising; an annular body having a plurality of insert pockets spaced around the periphery of said body, a plurality of identical inserts indexable about an axis extending transversely of the axis of said body located in said pockets, each of said inserts having a plurality of identical evenly spaced peripheral cutting teeth, locating means differently positioned in successive pockets in said body adapted to engage and locate any one of the teeth of respective insertS in successive phased relation to provide a progressive fractional distribution of cutting action, and the cutting teeth of each insert being indexable in any one of said pockets to present alternate identical cutting teeth in identical cutting position of any one of said pockets.
Claim 2
Dependent Claim
123 words
A rotary cutting tool comprising; an annular body having a plurality of insert pockets spaced around the periphery of said body, a plurality of identical inserts indexable about an axis extending transversely of the axis of said body located in said pockets, each of said inserts having a plurality of identical evenly spaced peripheral cutting teeth, locating means differently positioned in successive pockets in said body adapted to engage and locate any one of the teeth of respective insertS in successive phased relation to provide a progressive fractional distribution of cutting action, and the cutting teeth of each insert being indexable in any one of said pockets to present alternate identical cutting teeth in identical cutting position of any one of said pockets.
Claim 3
Dependent Claim

Claim 12
Dependent Claim
28 words
A cutting tool as set forth in claim 10 providing a number of insert index positions in each pocket equal to two times the number of insert teeth.
Claim 13
Dependent Claim
36 words
