Klein Tools D257-4 – Frequently Asked Questions

1) Can I use the Klein D257-4 cutters on live circuits?
No. The D257-4 is not insulated, and the plastic-dipped handles are there for grip and identification only, not shock protection. De-energize the circuit before cutting, and wear approved eye protection. If you need to work energized, you need a VDE/1000V insulated cutter, not this one.
2) What size wire will the Klein D257-4 electronics cutter handle?
These are small electronics cutters, not a general-purpose lineman's cutter. The jaws open to a 0.75 inch capacity, with a jaw length of 0.518 inch and jaw thickness of 0.24 inch, so they're sized for fine electronics leads, small-gauge stranded and solid wire, and tie wraps. For larger building wire, step up to a full-size Klein diagonal cutter.
3) Will these cutters reach into a tight panel or crowded terminal block?
That's what the tapered nose is for. At 4.26 inches overall with a 0.438 inch jaw width and a narrow tapered nose, the D257-4 gets into confined areas and cuts close to the tip where a full-size diagonal cutter can't get the jaws in. Handle length is 2.75 inches, so it works as a one-hand tool in a control cabinet or device box.
4) Does the D257-4 cut flush, or does it leave a stub on the lead?
Semi-flush. The induction-hardened knives on the D257-4 are semi-flush with beveled cutting edges, so a cut component lead is left with a small pinch rather than a perfectly flat face. For board work where you need a true flush cut with no protruding stub, use a flush-cut electronics nipper instead.
5) Are the Klein D257-4 pliers approved for tethering at height?
No. The D257-4 has no tether point and isn't rated as tether capable, so it shouldn't be tied off for work on a lift, scaffold, or tower. If your site requires drops protection, specify a Klein tool from the tether-capable line.
6) What is the Klein D257-4 made of, and will the joint loosen up with use?
Steel jaws forged in the USA from Klein's own US-made tool steel, with a hot-riveted joint. The hot rivet is what keeps the action smooth and stops handle wobble over time, unlike a screwed or cold-set pivot. Tool weight is 0.12 lbs.
7) How do I identify the D257-4 in a shared tool crib?
By the light blue plastic-dipped handles, which is how Klein color-codes this electronics cutter, and by the D257-4 stamp on the tool. It's a 4-inch tapered-nose narrow-jaw diagonal cutter, noticeably smaller than the standard side cutters in the same drawer.
