Abstract: A tool for cutting material includes a holding member having a slit-like opening forming first and second spaced jaws, a cutter insert mounted between the spaced jaws in the slit-like opening, and a positioning arrangement on the holding member positioning the cutter insert in the opening, whereby the spaced jaws hold the cutter insert with a predetermined clamping pressure providing for proportional increase of the clamping pressure relative to the cutting pressure applied to the cutter insert.

Abstract: Single or multiple recessing tool with cutting plates loosely mounted in an opening of the holder with the cutting plates, possibly using shortened gage block-like supplemental plates, clamped against the bottom and one side wall of the opening by means of an essentially L-shaped mounting frame overlapping the plates of the plate package from above and one side with a clamping pressure component being produced when clamping the mounting frame against the bottom via a wedge ramp lateral to the side wall and with adjusting ribs being arranged on the bottom of the opening and/or the bottom side of the upper clamping leg of the mounting frame engaging into the fitting grooves of all of the plates.
