Sturdy design - To ensure optimal tool life, the cutter and die insert are made of tungsten carbide and the other parts of the nibbler head of high-grade steel. Good accessibility - The cutter works in the upward direction reducing the risk of die failure. The die insert has cutting edges all round and can be rotated through 360 degrees before being worn out. Piped-away exhaust air - Some of the exhaust air is conducted through the nibbler head so as to blow out the chips and cool the cutter.
