Wire Cutters

Select by wire type and task: diagonal cutters for general-purpose cutting of soft copper and insulated wires, side-cutting pliers for trimming and holding, and heavy-duty bolt cutters or cable cutters for thick or steel cables; match jaw hardness and cutting capacity to the conductor material and diameter

Check the maximum cutting diameter (often listed in mm or AWG) and choose hardened tool steel or induction-hardened cutting edges for clean cuts on copper/steel; softer edge materials are fine for light-gauge electronics work but wear faster on hardened wire

Insulated handles protect against shocks but must be rated for electrical work; look for tools rated to 1000 V or meeting relevant IEC/EN standards if you will work on live circuits, otherwise non-insulated ergonomic handles suffice for low-voltage and mechanical tasks

Wire cutters range from budget options under $30 to professional tools over $100; higher-priced models typically offer better edge retention, ergonomic grips, and durability, which can be cost-effective for frequent or heavy-duty use

Keep cutting edges clean and free of nicks, lubricate pivot points periodically, sharpen or replace blades when dull, and store in a dry place to prevent corrosion; avoid cutting materials above the tool's rated capacity to prevent damage

Wear eye protection to guard against flying wire fragments, secure the workpiece, cut at right angles for cleaner cuts, and avoid cutting live electrical conductors unless using insulated, rated tools and following voltage safety procedures

Replace the tool if cutting edges are chipped or deformed beyond sharpening, if the pivot is seized or permanently loose, or if insulation is damaged; replace rather than repair when cost or safety risks outweigh refurbishment
