Channellock 7 In. Diagonal Cutters
The Channellock Diagonal Cutters (337) are a robust and durable tool ideal for professional and DIY use, thanks to their sharp, heat-treated cutting edges and ergonomic design. However, they do lack some features like a spring return and wire stripper, and they are not designed for nonsparking or ESD environments. If you are in need of a reliable set of diagonal cutters for general use and can overlook these cons, they are a solid choice.
