Abstract
Abstract A boring tool has a cutter mounted on a holder adjustable relative to the boring tool body. Adjustment of the cutter holder is effected by displaceable wedging surfaces in engagement with each other, one of such wedging surfaces being provided on the cutter holder and the other being provided on an adjustably displaceable wedge piece, the cutter holder body being substantially cylindrical but prevented from rotating by the wedge piece having a plane surface in engagement with a plane surface of the cutter holder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
In a cutting tool rotatable about an axis of rotation wherein the position of a cutter holder is adjustably displaceable in a direction transverse to said axis of rotation by way of a wedge piece slidable in a direction transverse to said axis of rotation and to the direction of displacement of said cutter holder, said wedge piece having a first plane surface in sliding engagement with a corresponding wedge surface on said cutter holder adjustably displacing said cutter holder in an appropriate guiding and holding recess extending in said direction of displacement of the cutter holder, the improvement comprising said cutter holder having a circularly cylindrical body slidably disposed along its longitudinal axis in a generally circularly cylindrical recess of said cutting tool, a cutout portion in said cutter holder defining a second plane surface substantially parallel to the longitudinal axis of said cutter holder and to the sliding direction of said wedge piece, and a corresponding third plane surface on said wedge piece in sliding engagement with said second plane surface preventing rotation of said cutter holder about its longitudinal axis.
Claim 2
Dependent Claim
183 words

Claim 3
Dependent Claim
18 words
The improvement of claim 1 wherein said second and third surfaces are disposed substantially at a right angle.
Claim 4
Dependent Claim
26 words
The improvement of claim 1 wherein the wedge surface of said wedge piece is engaged with the wedge surface of said cutter holder by spring bias.
