1 Claim. (01. 29-95) This invention relates to improvements in of two narrow, spaced cutting edges 4a formed tools, and refers particularly to parting tools for across the aligned faces 4, and a third cutting use on lathes, automatic machines and the like. edge 5a across the depression 5.
It is an object of the invention to provide a Consequently two narrow, separate cuts are 5 parting tool by which a plurality of separate, taken in the work, diagrammatically indicated at 5 narrow cuts are taken substantially simultane- A in Figure 2, and a third delayed cut is taken ously to obviate the necessity for the use of chip by the depression cutting edge Ia. The latter cut breakers which frequently have to be employed is retarded both by the fact that the depression with ordinary high speed parting tools which is below the faces 4 upon the downwardly and intake only one cut, due to the fact that the long wardly inclined end of the tool, and also by the 10 winding chips which so quickly form are otherfact that whereas the faces 4 are disposed subwise, when in one piece, large and heavy enough stantially radially to the work A the depression to hinder the proper handling of the machine. 5 is below that radial line.
Another object of the invention is to provide It will therefore be clearly seen that I have such a parting tool having a cutting head extenddevised a simple form of parting tool by which 15 ing longitudinally thereof across one extremity a plurality of separate, narrow cuts are taken over of which an easily ground cutting surface is the surface across which the parting tool operformed; to provide two narrow, aligned marginal ates. Consequently instead of having a single faces lengthwise of the head the extremities of chip which forms a sufllciently heavy coil to inwhich form two narrow, spaced cutting edges; terfere with the manipulatlonof the machine un- 20 and to form a marked central depression longlless a chip breaker is employed, a plurality of tudinally of the head between the marginal faces correspondingly narrower chips are formed which whereby the extremity of the depression constlmay be readily broken and d sposed of. tutes a third cutting edge by which a retarded Moreoyer, while the substantially flat depres- 2 third cut-is taken.

A parting tool comprising a narrower body and My parting tool consists of a lower portion or a wider head each extending longitudinally of body I having parallel sides 3 and a relatively the tool and each of uniform width throughout shallow upper portion or cutting head I integral their entire length, the opposite sides of the head therewith.

The width of formed longit in lly 1 1 8 1 m l n n 8 the head 2 is greatest at its upper extremity and central depression between said edges, the tool throughout their depth and sides 3 of the head being adapted to be fed longi din y int rotat- 2, which are downwardly and inwardly inclined ing work along a line substantially radial to the to provide clearance, extend laterally beyond the work axis whereby the length of the line of cut sides I of the body I. is increased by said depression and the resultant One end of the tool is downwardly and inwardchips broken h r d l l having & ly inclined along a straight line along which the downwardly and inwardly E lm flat ffloove rofll tool may be ground from time to time.
