Improved nibbler design provides maximum comfort and ease of use. The extra long handles (7") delivers enough force to easily cut through 18 ga. (.046") aluminum, steel, or plastic. The punch action of the nibbler makes it flexible enough to cut any shape ranging from a straight line down to a 5/16" radius circle. Simply drill a 3/8" starting hole and insert the punch and begin cutting by squeezing the handles together to remove material one slug at a time. That's all there is to it. Your cuts will be clean and completely burr-free. Ideal for creating access areas, instrument holes, lightening holes, and other applications requiring a clean, accurate cut. 1 lbs (0.5Kg) shipping weight.
