The No. 4 shear with its standard blade is expressly designed to cut up to 2″ x 2″ x 1/4″ angle iron and produces a clean, burr-free cut every time.
The No. 4 Angle Iron Shear is offered with three types of shear blades; standard, contour and special. The standard blades are installed at the factory and all No. 4 shears are shipped with these blades. The contour and special blades must be purchased separately and installed by the user. The same base shearing die can be used with all three shear blades. Shearing 2” x 2” x 1/8” angle without distortion requires a special blade which also cuts other sizes as shown for contour blade.
Since the extreme capacity of this tool is accomplished by a shearing action, there is a bending out or distortion of one leg of the angle iron when using the standard movable shear blade. To avoid this distortion, a contour moveable shear blade is offered to cut 1/2” x 1/2” x 1/8” to and including maximum contour capacity of 2” x 2” x 3/16”.
