Title: Grooving and cut off tool

Abstract: A grooving and cut off tool in which a barlike holder is provided with a thin blade secured thereto at one end and projecting outwardly therefrom. The blade has a groove extending longitudinally along the upper edge thereof and a hard wear resistant insert is mounted in the groove near the forward end thereof. A clamp member is provided which is secured to the bar-like holder by a screw and which has a portion also engaging the groove in the blade-like member rearwardly of the insert and with the clamp member having a resilient tongue engaging a notch provided in the top of the insert. The clamp member has an abutment region engaging the rearward end of the insert and the clamp member is adjustable in the fore and aft direction of the blade member to compensate for change in length of the insert when it is ground off at the outer end.
