Basically a replacement for hand snips and shears, a nibbler cuts through metal like a jigsaw, but instead of a blade, a nibbler uses a sharp punch that moves up and down through a die to create the cut. Metal shops usually use gas versions, while contractors usually like electrical or conductor models.
Using a nibbler
A nibbler is used very like a jigsaw. The main difference is there's no table on the biter to ride on the fabric. Make certain the body of the biter remains parallel to the fabric you're cutting or the tool can bind.
If you are beginning a cut within the middle of the fabric, use a drill to create a starter hole. The minimum starter hole radius is also such that on the tool?s packaging. Also, if you are ending a cut within the middle of the fabric, you?ll typically have to back the tool out of the cut. You usually can?t raise the tool out of the kerf.
When cutting, you can flip the fabric if you're acting on atiny low piece or flip the tool very like a jigsaw. Most nibblers feature a die holder that rotates so you will stop the tool from bottoming out against any obstructions. To make precise or straight cuts, you can use a spread of shop-made jigs, templates, guides or straightedges.
Be aware of where the metal chips land as you narrow. These can be very sharp and may cause injuries or mar the surface of finished items. The chips from some nibblers will simply fall out anyplace, while some tools direct chips downward.
The cut will have sharp edges and burrs that might have to be compelled to be planate or deburred. Depending on the supposed use for the piece, you can use a hammer to flatten the sides against another pave or polish the sides with a grinder or metal smoother.
