An improved cutoff tool made up of a tool body, a support blade clamped thereto, and a clamping member adapted to be secured to the tool body and overlie the support blade so that an insert bit and stop member may be clamped between the clamping member and the support blade, with the support blade and the tool body interlocking so as to provide added rigidity and extreme compactness.
