four cutting edges of premium quality tool steel and will
withstand nicking and wear better than relieved blades.
National blades are secured to the shear with tempered flat
head screws through countersunk holes in blades.
Complete cuts of full width pieces are 2" longer than
specified cutting length. This high strength cast iron
constructed frame made of the highest tensile strength
metal needed for long life and accurate shearing.
Underdrive contruction with downward cylinders and major
hydraulics under the bed gives the shear a low profile.
