How Thick a Metal Will Nibblers Cut?

Nibbler Basics

• Nibblers range from those that cut through the metal exactly like a pair of scissors to those that use linear blades working against a fixed die that removes tiny pieces of metal as it nibbles its way along through the sheet. Both work equally well and are designed so they don’t bend or distort the metal as they cut. However, they are limited because they only work with sheet metal.

Maximum Thickness

• The thickness of the material isn’t the only concern; the type of material also must be taken into consideration. Generally, you can use nibblers on any type of sheet metal up to a 1/2 inch thick, provided that the metal is a softer type. The softer the metal, the thicker the nibbler can cut through. Different manufacturers have recommendations on maximum thickness and material types.

Handheld

• Because handheld nibblers are only as strong as the person using them, you are limited to either softer metals or paper-thin sheet metals. Your own strength is the main limiting factor when you are working with the handheld versions of nibblers, and the only way to know is to try and cut through a piece to see whether it’s feasible.

Electric vs. Pneumatic

• Automatic nibblers come in either electric or pneumatic models. They both have their own sets of pros and cons based on the manufacturer, and it basically comes down to personal preference as to whether you prefer an electric version or a pneumatic. While the former merely needs an electrical outlet, the latter needs an air compressor unit as well as a hose and connectors, which makes the electrical version more accessible to the average homeowner.
