CHZHLM RJ45 pass-through crimp tool kit with 50 connectors, covers, mini stripper and cable tester

What it is and why people buy it

This CHZHLM RJ45 crimp tool kit is a combined setup for making RJ45 connections using pass-through connectors. The “pass through” idea matters: you insert the wires through the connector first, so you can check the wire order before you crimp. Over the course of a few terminations, that extra step can save time and reduce the “I crimped it but the order’s wrong” frustration.

It’s also designed to be a do-it-yourself style toolkit rather than a bench-only crimper. On paper, it bundles cutting, stripping, and crimping into one tool, plus the small extras you’d otherwise be hunting for.

The essentials (what you get)

The pack includes the crimping tool, a yellow mini wire stripper, and a network cable pliers. It also comes with a batch of parts: 50x Cat6 RJ45 pass-through connectors, 50x blue strain relief boots, and a cable tester labelled RJ11/RJ45.

A couple of practical notes from the listing are worth clocking before you buy: - The cable tester requires a 9V 6F22 battery (not included). - The connectors have a stated maximum insulated wire outside diameter of 1.1mm for 24awg cable.

Key takeaways on performance and usability

The headline feature here is the pass-through crimper. Using pass-through RJ45 connectors is generally a convenience play for installers who want visual confirmation of the sequence. If you’ve ever had to rework cables after the crimp, you’ll understand why people like this approach.

The tool is also described as a compact design (around 2/3 the size of a traditional crimper). In day-to-day use, that kind of size difference is often about comfort: less bulk in the hand, easier manoeuvring around a patch panel or cable run, and potentially a better grip for short bursts of work.

That said, it’s not positioned as a specialised pro-grade tool with deep, performance metrics included in the description. If you’re planning heavy, frequent crimping all week, you may find yourself comparing it against higher-end tools where tolerances and long-term consistency are more of a focus.

Where it shines (and where it may not)

It makes sense if you’re: - building or repairing a handful of Ethernet leads and want a tool that covers the basics (strip, cut, crimp) without a separate workflow - using RJ45 pass-through connectors and appreciate the ability to check wire sequence before crimping - after a kit-style purchase that includes the connectors, boots, and a simple RJ11/RJ45 tester

It may not suit you if: - you need a tester with guaranteed features beyond the listing (the description only tells you it’s an RJ11/RJ45 tester and the battery requirement) - your wiring doesn’t fall within the stated insulated wire outside diameter limit for the supplied connectors - you’re set on a very particular crimping style or already have a bench-grade tool and don’t want a bundle

Tech summary (based on the info provided)

Materials, compatibility and key limits

This kit is designed for RJ45 pass-through connectors and is described as usable across RJ45 pass-through shielded or unshielded connectors, with mention of Cat5/5e, Cat6/6a. The included connectors are stated as Cat6 pass-through types, with a maximum insulated wire outside diameter of 1.1mm for 24awg cable.

Mini FAQ

Will this work with standard RJ45 connectors?

The description is specifically aimed at RJ45 pass-through connectors, so if you’re using non-pass-through connectors, you’ll want to double-check compatibility first.

Does the cable tester come with a battery?

No. The listing states that a 9V 6F22 battery is required and not included.

Is it only for Cat6?

The supplied parts are Cat6 pass-through connectors. The tool itself is described as usable with RJ45 pass-through shielded or unshielded connectors including Cat5/5e, Cat6/6a.

Is it a full tool kit for making cables?

It’s meant to cover the main steps: cutting, stripping and crimping are included in one tool, and it’s bundled with connectors, strain relief boots, and a tester.

Buying verdict

Is it worth it?

It’s a solid pick if you’re doing normal home or small-workshop networking jobs and want a bundle that supports pass-through RJ45 terminations, including the connectors/boots and a basic RJ11/RJ45 tester. The pass-through design is the bit that justifies the kit’s “all in one” feel—being able to check the wire sequence before crimping is the practical advantage you’ll notice.

You may want to skip it if you’re already set up with your own crimping and testing equipment, or if your cables/wiring don’t match the connector limit mentioned (maximum insulated wire outside diameter of 1.1mm for 24awg cable). As with any all-in-one kit, it’s value-for-money in the right context, but it can feel like overkill if you only need a single component rather than the full set of extras.
