Claims: Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A screw machine cut-off tool in which the cutting point of the tool blade is supported in tension, comprising

a removable tool blade, formed with two arm sections joined to a stiffener section,

a blade holder formed with a shank joined to two separated arm members, with fastening means to frictionally mount each arm member of the blade holder to an arm section of the blade,

said tool blade fitted with a cutting point located between the two arm sections of the blade with the stiffener section extending from the rear portion of the blade opposite the cutting point on the forward end of the blade,

said blade holder and said blade fitted with adjustable mating means to positively engage a first arm member of the blade holder with a first arm section of the blade, with the second arm member of the blade holder being frictionally engaged to the second arm section of the blade,

said first arm section of the blade being oriented with respect to the cutting point of the blade in the same direction as the relative direction the cutting point moves toward work to be cut so that the engaged positive said mating means applies a tension force to said first arm section of the blade in use,

said blade holder fitted with bearing means to slidably support the end of the stiffener section of the blade.

2. The combination as recited in claim 1 in which the mating means for engagement of the first arm member of the blade holder and the first arm section of the blade comprises a plurality of grooves on an edge of the blade, with a pin fitted in the blade holder of a size to fit in one of the grooves of the blade, so that the blade may be alternately located in one of a plurality of positions with regard to the blade holder.
