The cutter c is threaded to engage the base of a spur wheel nut g the face g<SP>1</SP> of which bears against the end of the cutters b. The amount of float may be limited from the maximum permitted by the nut d by conical ended grub screws engaging depressions in the cutters to an adjustable extent. The pinion is engaged by teeth h<SP>1</SP> on a spindle h having a cross slot h<SP>2</SP> for rotation as determined by graduations and an index mark. Locking is effected by the screw i.
