Abstract: A draw-knife for producing keyways and for profiling workpiece bores comprising a knife bar whose head portion carries a cutting member which comprises two knife plates arranged side by side in the same plane and being coaxially adjustable, and an immobile knife plate provided behind the latter in the drawing direction of the draw-knife. The cutting edge of the immobile knife plate bridges a gap between the inner ends of the cutting edges of the two adjustable knife plates. The length of the cutting front of the cutting member of the draw-knife is changeable thus allowing one sole tool to adapt to any desired width and fit of the desired grooves or profiles.
