<p>A cutter device has a cutter portion (40) which is led by a depth gauge (52). The depth gauge (52) is mounted on and extends upwardly from a substantially planar main body section (32). The depth gauge (52) has a forward, or first section (52a) which extends upwardly from the main body (32), and when viewed from above is disposed at an angle (A) relative to the central plane (33) of the main body (32) diverging therefrom on progressing rearwardly. The rear end of the first section (52a) is connected at a juncture section (52c) to a second section (52b) which progresses rearwardly and is disposed at an angle (B) converging toward the central plane (33). The second section (52b) may extend across the plane of the body and diverge from the opposite side thereof on progressing rearwardly. The upper surface (58) of the depth gauge (52) presents a sweeping curve as viewed from the front of the cutter (40) which is a multiple of the thickness of the body (32) to which it is attached to provide effective cut control for the following cutter (40). <IMAGE></p> |
