Knipex 97 51 10 Crimping Pliers

This Knipex 97 51 10 crimping tool handles RJ-11/12 six-pole and RJ-45 eight-pole connectors with crimp capacities of 9.65 mm and 11.68 mm respectively. The 7 1/2 in steel body includes integrated wire cutter and stripper functions. Deluxe cushion grips provide manual adjustability for professional telecommunications and data cabling work.

Telephone and network cable installers

Suits technicians terminating Western plug connectors on telephone and network cables who need a single tool for both 6-pole and 8-pole positions. Not suited for users requiring insulated handles, interchangeable die sets, or crimping capacity beyond the stated 9.65 mm and 11.68 mm specifications. Builders needing coaxial or fibre termination should look elsewhere.

Ready to use from the box

No assembly or die installation is required because the crimping profiles are fixed into the jaws. The manual adjustability lets operators set pressure by feel. Common issues include misaligned conductor insertion before crimping and applying excessive force that can damage the connector housing or tool pivot.

Questions about this item

What connectors do I need to have on hand for the Knipex 97 51 10 to crimp?

The tool crimps RJ-11/12 6-pole plugs at 9.65 mm and RJ-45 8-pole plugs at 11.68 mm, so keep those connector types in stock.

Can I still use the Knipex 97 51 10 if I keep my older telephone cable?

Yes, the crimper is compatible with telephone cable and the same RJ-11/12 and RJ-45 Western plugs used on legacy installations.

How do I verify the Knipex 97 51 10 is crimping correctly after setup?

A proper crimp seats the plug fully in the 9.65 mm or 11.68 mm die, locks all contacts flush, and the built-in cutter and stripper leave clean ends without insulation damage.
