When the greater length of a standard boring tool is more a hindrance than a help, Criterion offers this line of Stubby Boring Tools. Maximum rigidity is assured whether the tools are used in a boring head or in the cross-slide of a lathe. As with the tools found in the Brazed Carbide & H.S.S. Boring Tools section, this line also features set-screw flats that commit the cutting edge to exact centerline.
Available in shank diameters of 1/2", 3/4" and 1", these husky tools are made in both HSS and carbide. Stubby Boring Tools may also be ordered with square shanks. Dimensions of square shank tools will be found at the Brazed Carbide & H.S.S. Boring Tools section.
The carbide line utilizes the same large triangular insert as used in the ABT and SBT series. Presently only a C-6 all-purpose grade of carbide is available. For other grades you may write or call for price and delivery information.
