Ask anyone who makes their own Ethernet cables about their worst crimp, and you will get a story. It usually ends with a little pile of cut-off plugs on the floor and a tester that refuses to show eight green lights.
Here is the comforting part: most bad crimps are not your fault. They come from sloppy dies, a blade that leaves wires half cut, or a crimper that simply does not match the plugs in your hand. Fix the tool and the job gets boring in the best way. Strip, sort, slide, squeeze, done.
We compared the best-selling standalone RJ45 crimpers on Amazon.com, matched each crimper to the plugs it actually supports on the maker's site, and favored tools that make clean, repeatable crimps. Then we read what installers and weekend DIYers say after real jobs, because plug compatibility is where most buyers go wrong.
Quick answer: The Klein Tools VDV226-110 is the crimper we would buy. It ratchets, trims pass-through plugs flush, and owners keep calling it the best crimper they have used. Using standard plugs? Get the Klein VDV226-011. Want something pocket-sized for pass-through work? The Klein VDV226-005 is a little gem.
Every pick is a crimper on its own, so you can pair it with the plugs and tester you already have. Starting with an empty toolbox instead? Our roundup of complete network tool kits bundles a crimper, tester and stripper in one box.
What we looked for in an RJ45 crimper
A crimper has one job, but several details decide whether it does that job well. Here is what we weighed:
- Plug compatibility. Pass-through and standard plugs need different tools, and some pass-through crimpers only trim their own brand of plug.
- Even pressure. A full-cycle ratchet or a rigid frame presses all eight contacts the same way, every time.
- A clean trim. Pass-through tools must cut all eight wires flush with the plug face, including the two on the outside.
- Owner feedback. We looked for recurring complaints, especially uncut wires and over-crimping.
- Warranty. Klein covers its crimpers for the normal life of the tool. We checked every other maker's terms too.

Klein Tools VDV226-110 Ratcheting Pass-Thru Crimper
- Plug type
- Klein pass-thru RJ45, RJ11/RJ12
- Mechanism
- Full-cycle ratchet
- Functions
- Strip, crimp, cut, flush trim
- Cable
- Cat3, Cat5e, Cat6, Cat6A (28-22 AWG)
- Extras
- On-tool wiring guide
- Warranty
- Limited lifetime
If a friend asked which crimper to buy and gave us no other details, this would be the answer. The VDV226-110 is the tool we would hand to a first-time DIYer and to a working installer, and owners in both camps seem to agree.
It is built around pass-through plugs. The wires slide all the way through the front of the connector, so you can check the color order before you commit. Then one squeeze crimps the contacts and trims the wires flush. The full-cycle ratchet will not release until the crimp is complete, which is what stops half-seated pins.
It also strips and cuts STP and UTP cable, takes 28 to 22 AWG conductors, and works with Cat3, Cat5e, Cat6 and Cat6A. An on-tool wiring guide keeps the T568A and T568B orders handy. The same tool crimps standard RJ11 and RJ12 phone plugs.
The track record is remarkable, and complaints are rare. More than 3,000 sell every month. Buyers keep saying it beats every other Cat5 or Cat6 tool they have owned and makes pass-through connectors easy.
The cutter is the part owners mention most, as it can dull with heavy use. Some owners find that wires 1 and 8, on the outer edges, are not always trimmed cleanly. A firm, full squeeze usually solves it, and Klein sells a replacement blade kit (VDV999-076) for when the edges dull.
One more thing: Klein designs it for its own Pass-Thru plugs, sold in packs of 10, 50 and 200, so buy those with it. Klein covers the tool for its normal working life.
What we like
- On-tool T568A and T568B wiring guide
- Full-cycle ratchet seats every pin
- Crimps and trims flush in one squeeze
- Also strips cable and crimps RJ11/RJ12
Good to know
- Made for Klein Pass-Thru plugs, so buy those with it
- Outer wires may need a firm squeeze to cut clean
- Not for standard RJ45 plugs (the VDV226-011 handles those)
Klein Tools VDV226-011 Ratcheting Modular Crimper/Stripper
- Plug type
- Standard RJ45, RJ11/12, RJ22 (not AMP)
- Mechanism
- Ratchet with safety release
- Functions
- Cut, strip, crimp
- Cable
- Round STP/UTP, flat phone cable
- Extras
- High-carbon steel dies, blade guard
- Warranty
- Limited lifetime
Not everyone wants pass-through plugs. Maybe you have a bin of standard RJ45 connectors, or your workplace specs them for a tidier finished end. Either way, the VDV226-011 is the Klein built for you.
This is a classic ratcheting modular crimper. It crimps 4, 6 and 8 position plugs, from RJ11 and RJ12 phone plugs up to RJ45 for Cat5e and Cat6. It also cuts and strips round STP and UTP cable plus flat phone cable. The dies are precision ground from high-carbon steel, and the ratchet has a safety release in case you need to back out of a bad crimp.
Owners like it a lot, and buyers keep praising the solid build and how easy it makes rolling your own cables.
Read the label on your plugs first, though. Klein designs this tool for Western Electric and Stewart Stamping style standard plugs. It is not compatible with pass-through plugs, Cat7 or Cat8 plugs, or AMP connectors.
The one mixed theme is over-crimping, where some owners felt they pressed too hard. Standard plugs need every wire pushed fully home and the jacket under the strain relief, so careful prep matters more here than with a pass-through tool. A quick test shows whether you got it right. Like Klein's other crimpers, it is covered for the normal life of the tool.
What we like
- Precision high-carbon steel dies
- Crimps 4, 6 and 8 position plugs
- Ratchet with safety release and blade guard
- Sturdy build owners keep praising
Good to know
- Standard plugs only (pass-through users want the VDV226-110)
- Check your plugs: not for AMP, Cat7 or Cat8 styles
- Careful wire prep avoids over-crimping
Platinum Tools EZ-RJPRO HD Crimp Tool (100054C)
- Plug type
- EZ-RJ45, EZ-RJ12/11, standard (not AMP)
- Mechanism
- Ratcheted, high leverage
- Functions
- Crimp and flush trim, cut, strip
- Cable
- Large OD, thick insulation, splines
- Extras
- 360-degree tool steel die
- Warranty
- 1 year
Platinum Tools invented the EZ-RJ45 pass-through plug, so it makes sense that its flagship crimper is the one to beat for heavy work. The EZ-RJPRO HD is built for installers who terminate thick cable all day and need the last crimp of the week to match the first.
Everything about it is aimed at tough Cat6 and Cat6A. The HD design copes with larger cable diameters, thicker and harder insulation and pair-separating splines. A zero-flex frame keeps force from leaking away mid-crimp, and the tool steel die head supports the plug a full 360 degrees.
The patented crimp-and-trim system leaves a flush cut on every EZ connector. There is also a built-in cutter and stripper for flat and round cable, plus a laser-marked wiring guide. Unlike Klein's pass-through crimpers, it is not tied to one plug family. Platinum Tools says it works with all EZ-RJ45 and EZ-RJ12/11 connectors and with standard modular plugs, except AMP.
As for downsides, the price is the main hurdle, since it costs noticeably more than the other picks. Its 1-year warranty is also shorter than Klein's lifetime cover.
That is a fair trade if you crimp for a living, and probably overkill if you make a few cables a year. For home use, the VDV226-110 or VDV226-005 will serve you well for less.
What we like
- Rigid frame built for thick Cat6 and Cat6A
- 360-degree die support for even crimps
- Crimps EZ pass-through and standard plugs
- Patented crimp-and-trim system
Good to know
- Costs more, but pays off with heavy use
- Trims best with Platinum EZ plugs
- 1-year warranty, shorter than Klein's
Klein Tools VDV226-005 Compact Pass-Thru Crimper
- Plug type
- Klein pass-thru RJ45 only
- Mechanism
- Compact, non-ratcheting
- Functions
- Crimp and flush trim
- Cable
- Cat3, Cat5e, Cat6, Cat6A
- Extras
- On-tool wiring guide, replaceable blades
- Warranty
- Limited lifetime
Picture a ladder, a ceiling tile pushed aside and one cable that needs a new end. Hauling a full-size crimper up there is a chore. The 5.5-inch VDV226-005 slips into a shirt pocket and does the job in one press.
It crimps and trims Klein RJ45 Pass-Thru plugs onto round STP and UTP cable in a single squeeze. An on-tool wiring guide helps you get the order right, and it handles Cat3 through Cat6A. The non-slip grip is comfortable, and replacement blades (Klein part VDV999-078) keep it cutting cleanly.
To stay that small, it skips a few things. There is no ratchet and no stripper, so pair it with a separate jacket stripper and make every squeeze a full one. Like its bigger sibling, it is designed for Klein Pass-Thru plugs only, not standard ones.
Owners are big fans of the size, and over 200 sell each month. Buyers describe it as sturdy, well made and easy to carry. One likes that it crimps and clips in a single press.
The mixed comments are mostly about technique. A few owners find loading the plug fiddly, and some report wires that were not fully cut. Both tend to improve with practice and a fresh blade. As a Klein hand tool, it carries the same lifetime cover as the VDV226-110.
What we like
- Pocket-size at 5.5 inches
- Crimps and trims in one press
- Replaceable blades (VDV999-078)
- On-tool wiring guide
Good to know
- Klein Pass-Thru plugs only
- No ratchet or stripper, so squeeze fully every time
- Loading plugs takes a little practice
Cable Matters Pass-Through RJ45 Crimp Tool
- Plug type
- Pass-through RJ45, RJ11/RJ12
- Mechanism
- Standard crimper
- Functions
- Cut, strip, crimp
- Cable
- Cat5, Cat5e, Cat6
- Extras
- 10 Cat6 pass-through plugs included
- Warranty
- None listed (30-day Amazon returns)
Sometimes you need three patch cables and a tool that costs less than the cables. That is exactly where the Cable Matters pass-through crimper fits.
It combines a cutter, stripper and crimper in a metal body with a soft grip. It handles pass-through RJ45 plugs and RJ11 and RJ12 phone plugs. Cable Matters also throws in a 10-pack of Cat6 pass-through connectors, so you can start the moment it arrives.
Owners are mostly content, and good quality and ease of use are the points you hear most.
Its weak spot is the blades. Some buyers say the jacket stripper can nick the wires inside, and others find the trimming blade does not always cut all eight. Strip gently, check the wires before you load the plug, and squeeze firmly to the end of the stroke.
Cable Matters does not list a warranty term for this tool on its product page, so check the Amazon listing before you buy. That, and the lack of a ratchet, is why it ranks fifth. For a handful of patch cables it is good value with plugs included. If you will crimp regularly, the VDV226-110 is worth the extra money.
What we like
- Low price
- Includes 10 Cat6 pass-through plugs
- Metal body with soft grip
- Cuts, strips and crimps in one tool
Good to know
- Strip gently, since the blade can nick inner wires
- A firm squeeze helps the trim blade cut all eight
- No ratchet, so it suits light use best
What we ruled out
Not everything that shows up in a search made our list. Here is what we left out and why, so you know what to avoid when you shop.
- Complete tool kits. Kits that bundle a crimper with a tester and stripper are a different purchase, so we review them separately. Every pick here is a crimper on its own.
- Unknown brands with little track record. Plenty of low-cost crimpers come from sellers with no history in networking tools. We kept to established brands with clear plug compatibility notes.
- Tools with a shaky reliability record. A crimper that fails one crimp in ten costs more in wasted plugs than it saves, so every pick here is consistently well reviewed by owners.
- Punch down and keystone tools. Keystone jacks and patch panels are punched down, not crimped. Those tools have their own roundup.
Buying guide: how to choose an RJ45 crimping tool for Cat6
The right crimper turns a bag of loose plugs into working Cat6 cables in about a minute each. The wrong one wastes plugs and patience. Three decisions do most of the work: the plug type, the mechanism and the cable you are terminating.
Choose the plug before the crimper
It sounds backwards, but the plug comes first. Standard RJ45 plugs have a closed front, so you trim the wires to an exact length and hope every one reaches the end. Pass-through plugs (also sold as feed-thru or EZ plugs) are open at the front. The wires poke out, you check the color order with your own eyes, and the crimper cuts them flush.
Pass-through plugs are faster and far more forgiving, which is why we suggest them to beginners. Standard plugs cost a little less and are still everywhere. Our side-by-side look at pass-through and standard plugs goes deeper on when each makes sense.
Match the crimper to the plug brand
This is the mistake that fills review sections. Klein's VDV226-110 and VDV226-005 are designed for Klein Pass-Thru plugs and are not meant for standard RJ45 plugs. The VDV226-011 is the opposite: standard plugs only, and not AMP-style ones. Platinum Tools' EZ-RJPRO HD trims its own EZ-RJ45 plugs and also crimps standard modular plugs, again except AMP.
When in doubt, buy plugs from the same brand as the crimper. It costs a few dollars more and removes the most common cause of half-trimmed wires.
Ratchet or no ratchet?
A ratcheting crimper will not open until the crimp cycle is complete, so every contact is fully seated. That consistency is why most professionals use one. Non-ratcheting tools, like the compact VDV226-005 and the Cable Matters, depend on you squeezing all the way every time. They work well, but a tired hand at the end of a long day is where weak crimps creep in.
Cat6 is thicker than you think
Cat6 and Cat6A conductors are heavier than Cat5e, the insulation is often harder, and many Cat6 cables add a plastic spline between the pairs. All of that makes plugs harder to load and crimp. Use plugs rated for your exact cable. If you terminate a lot of thick Cat6A, a heavy-duty tool like the EZ-RJPRO HD is worth the money.
Still choosing cable? Our guide to Cat5e versus Cat6 explains which one your network needs.
Wire order: pick one standard and stick to it
Every crimper here works with T568A or T568B. Most US patch cables use T568B, and both ends of a cable must match unless you are deliberately making a crossover.
Our explainer on the T568A and T568B color codes covers why two standards exist. Our walkthrough for making an Ethernet cable takes you from bare cable to a tested patch cord.
Test every cable before it goes into a wall or a rack. A crimp can look perfect and still have one weak pin. Our guide to Fluke cable testers covers everything from simple verifiers to speed qualifiers.
The rest of the toolbox
A crimper is one tool among a few. You also need plugs that match your cable and crimper, plus a decent jacket stripper if the built-in one is basic. Strain relief boots are worth adding if you want ends that do not snag. Buy plugs in bigger packs, since a few always go to practice.
Shielded cable needs shielded plugs, with a metal shell that touches the cable's foil or drain wire. And if you are terminating keystone jacks or a patch panel, those connections are punched down, not crimped. Our picks for the best Cat6 punch down tools cover that side of the job.
Five habits that fix most bad crimps
- Strip only what you need. About an inch of jacket is plenty, and the pair twists should run as close to the plug as you can manage.
- Flatten and straighten. Straight, flat wires slide into the plug channels evenly instead of crossing over.
- Push all the way home. With standard plugs, every copper end should touch the front wall of the plug.
- Keep the jacket inside. The strain relief tab must clamp the jacket, not loose wires.
- Finish the squeeze. Never stop halfway, especially with a non-ratcheting tool.
Keep the blades sharp
Pass-through crimpers trim wires on every squeeze, so their blades wear. Klein sells replacement blade kits for both the VDV226-110 (VDV999-076) and the VDV226-005 (VDV999-078). If the outer wires start staying attached, a firmer squeeze or a fresh blade usually fixes it.
Final verdict
The Klein Tools VDV226-110 is the best RJ45 crimping tool for Cat6 for most people. It ratchets, so every crimp is full and even, and it trims pass-through plugs flush in the same squeeze. Paired with Klein Pass-Thru plugs, it makes reliable cables quickly, even if you have never made one before. It also strips and cuts cable, so for most home and office jobs it is the only tool you need besides a tester. It is built for years of regular use, not just one weekend project.
Prefer standard plugs? The Klein VDV226-011 is the classic choice. Installers who crimp thick Cat6A all day should look at the Platinum Tools EZ-RJPRO HD. If you want something lighter for a tool belt, the Klein VDV226-005 is a compact pass-through option. Whatever you pick, match your plugs to your cable, because most failed Cat6 cables come down to the wrong plug, not the wrong tool.
Frequently Asked Questions
What is the best RJ45 crimping tool for beginners?
A ratcheting pass-through crimper like the Klein Tools VDV226-110. Pass-through plugs let you check the wire order before crimping, and the ratchet makes sure every crimp is finished.
Can I use any crimper with pass-through RJ45 plugs?
No. Pass-through plugs need a crimper with a built-in trimming blade, and some tools only trim their own brand of plug. Klein's pass-through crimpers are designed for Klein Pass-Thru plugs, while the Platinum Tools EZ-RJPRO HD is made for EZ-RJ45 plugs.
Do I need a special crimper for Cat6?
You need plugs rated for your Cat6 cable and a crimper that supports them. Cat6 wires are thicker and the cable often has a spline, so a sturdy tool helps. All five picks here work with Cat6.
Why does my crimped cable not work?
The usual causes are wires in the wrong order, wires not pushed fully into the plug, or one weak contact. Re-crimp with a firm, full squeeze, use the same wiring standard on both ends, and test every cable.
Is a ratcheting crimper worth it?
Yes, if you make more than a few cables. A ratcheting crimper will not release until the crimp is complete, which gives consistent results and far fewer failed terminations.
