Abstract
Abstract A machining tool for forming a surface and including a plurality of removable tool holders each of which holds one or more throwaway tool inserts. The tool holders are constructed so as to rigidly hold the tool inserts for precluding damage to the cutting edges of these inserts. In addition, the tool holders accurately locate the individual tool inserts.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
In combination: a cutting head or the like defining a recess adapted to receive a tool holder received in said recess; said tool holder comprising a first member having a first locating surface, a second member juxtaposed to said first locating surface of said first member, said second member having a second locating surface extending substantially perpendicularly to said first locating surface, a clamping member having a clamping finger portion and means for affixing said first member, said second member and said clamping member together with said clamping finger being supported in a cantilevered fashion, said clamping finger having a third surface facing said first locating surface and defining with said first surface and with second locating surface a tool-insert-receiving recess for receiving a tool insert, said first locating surface and said third locating surface being normally spaced apart a distance greater than the corresponding dimension of the received tool insert for free insertion and removal of the tool insert to and from said toolinsert-receiving recess; and clamping means carried by said cutting head and engageable with said clamping member for cantilevered deflection of said clamping member into gripping engagement with the received tool insert.
Claim 2
Dependent Claim
