A little tip from an avionics person that uses a Daniels Tool that is similar to this but of much higher quality...Put the crimp lug into the tool and pull it up to the detent on the die, and crimp down till the tool just holds it in place. Then jam your wire up into the lug and crimp it down. Less manipulation needed to hold 3 things with two hands that way.

[@rodx5571]

I use similar tools for making flare fittings and such, sometimes, in off vehicle scenarios you can place the tool in a vice (gently of course) or an apparatus i created with rubber, hose clamps and a piece of 2x4 to put it in a vice. For production stuff this is awesome, and using your method of using jaws to initially hold the lug, it gets easier.

[@BURNETTWEALTHGROUP]

This is going to be a game changer for me. Glad I stumbled onto this video thanks

[@back40flopdogg30]

I have this tool and it's a beast, going all ring terminal from here on out.

[@rainyboy911]

This crimper is a pleasant surprise, really love it, great value.

[@jtr82369]

Great video on this tool I get the terminal set in the tool first and then push the wire in, makes it easier than lining up the terminal on the wire and hoping it doesn't get knocked sideways

[@MikeWolf-427]

Duck Doughnuts! We've got one of those here in Williamsburg. :) Cool tool, I was searching for a crimper when I found your video.

[@nitrous07me]

Great review 👍

[@mr.18s73]

Sweet review

[@akbychoice]

Used an old bud nut, wheel weights and a torch. Put wheel weights in the Bud nut, use torch to heat it, dip the wire ends into the molten lead to Tin the ends. Makes for a long lasting connection.

[@dennissecor8092]

Excellent video thank you!

[@parkerbirch1475]

Thank you. Great video!

[@fisherus]

Just a note when using this tool. Do not over pump the hydraulic fluid by putting too much force on the pump handle or you risk breaking the jaw that holds the crimp inserts. Just pump until it becomes firm.

[@larryrodriguez5063]

Looked at it today at harbor freight and after watching this great video I’m going back to purchase it tomorrow thank you great video demonstration !

[@bigdaddysshop8180]

That's what I've always done. Pump it till firm and release pressure.. SO SATISFYING.

[@JimmyMakingitwork]

Cool tool, looking at getting one. I have been using a hammer and punch technique, but this is much better.

[@TheRossco95]

Thanks for the great camera work. I suggest that forcing the crimp tighter with both hands should be avoided as this can result in over-compressing and breaking of wire strands.

[@josephklimchock5412]

Nice review of the tool. I however cut the cable insulation back a but more, then push the cable full forward into the cable end. I also do not twist the cable, If the cable is the same size as the end, as it should be, twisting the wires has no benefit, and it might be better to crimp with wires straight in, just like a factory made cable, but everyone has their way.......IMO........nice vid though

[@smithraymond09029]

I was seriously considering buying this tool. It's about $70 at my local store. I need to replace several electrical connections on my car. I believe it would pay for itself after I make 2 cables vs. buying an set of own cables at the dealer.

[@JohnWick-bb9jl]

And you have the ability to use higher quality wire than probabley the OEM stuff is.

[@kennymartin379]

Great job

[@harryinoklahoma1866]

I've had one of those since 2008. Seldom use it but its invaluable when I need it. Never had a crimp fail after crimping with this tool. I'd recommend using an alligator clip or something similar to hold the wire while you crimped it with 2 hands. Mine is so old the dies aren't magnetic.

[@billsmith2212]

I saw another post and before the shrink tubing gets heated , they put in dielectric grease to keep moisture out .

[@allb4dinner962]

I start with one hand too then i finish with too, i know it's a lil much but it works

[@CantKillMe]

i have one that is very old now and it went thow a shop fire and it still works but my dies run a little big so if you run 8gag then you need two us 6gag to crimp right

[@JaySain69]

Thanx a lot mane 💰💰

[@Fireship1]

I use one of these and follow up with a lug dip in a solder pot. The connections will outlast the equipment you wire them to.

[@srira7910]

We found these over crimp AWG 6 cable, and the hydraulic leaks after awhile. Suggest investing in a professional grade Crimper, you don't want heat due to voltage drops.

Will this work on 1/4" pressure washer hose rated for 2000 psi? 3/4" garden hose? How do you take the old brass (?) crimp off if you dont want to damage the barb inside the hose? Thanks👍

[@robert574]

Good video. Is there any way you could tell me the outer dimensions of the dies are L x W x Thk. (just one half) and maybe what the size of the largest hex opening would be? Not sure if you might have a pair of calipers to get a good measurement. I couldn't find a drawing or dimensions anywhere.

this is a awesome crimper use with marine glue grade shrink wrap the ends should not ever corrode thats the extreme battery cables..i just bought one to do battery cables cause to buy them already made is like 250 bucks for golf cart i can make them a lot cheaper an they extreme good i even color coat the ends so noway can put cables in wrong place on a golf cart..wasnt sure if i did it to hard an flared out the end on the cables but i guess i did it correct i kept going to it would not go any further

[@guyfranks4354]

Wouldn't it be easier to lightly crimp the lug in the dies then insert the wire?

[@arthuralzamora7331]

Note: if you over compress the hydraulics ( keep pumping ) after it is crimped you can break or crack the hydraulic head!

Well......... Some people's children.........

[@chrishale8714]

I’d use a vise and lock the head in the vise to might help the process

[@johnny0454]

What you are producing are not factory quality. I don't know if you are using metric lugs, or what,? but they do not fit those dies. A proper crimp, which "cold welds" all the strands uniformly to the lug and eliminates all air pockets, doesn't have wings like that. The dies are supposed to come together completely forming a perfect hexagon with no "wings." If you were to cut those crimps open, you would see air pockets in the cross section, between the strands and/or the lug itself, which will oxidize over time, as well as reduce the electrical conductivity greatly by reducing the area of contact between the conductor (wire) and the lug (termination). Those crimps are not a "gas tight" crimp, which is the goal in automotive cables. A factory, or perfect, crimp would show a cross section when cut open of one solid piece of copper, you would not be able to see or differentiate between single strands or the lug itself.

[@rickjeffjeff]

I will shorten your novel...... That is an incorrect crimp......

[@johnny0454]

@@rickjeffjeff and yet does nothing to educate or teach why it is incorrect, your comment is a waste of words and time.

[@richieortiz5]

I was wondering about the wings as I bought this tool myself and am crimping a 6ga battery cable for a 1970 Honda cl175. The factory cable uses a barrel(?) style crimp the same as it does on the 18 ga connectors. Traditionalists would want the same style of crimp for restorations but I’m not even sure how to get ahold of does to crimp in this manner. My crimps on this 6ga ring terminals have the wings like on this video. Would crimping with the 4ga dies prevent winged crimps? Just thinking out loud. Thanks for he video to the OP.

[@gregjohnson-il2oz]

have used this tool and it dosen't seal ram every pump are there seals to change? have used larger tools as an electrician this size and weight is great just need ram to hold pressure every pump

[@BobbyJr556]

Is there a cordless tool like this, Preferably for wire ropes?

Do you mean Zero Gauge cable or sometimes referred to as Aught? You can get down to 4/0 gauge which is often used in welding leads if that is what you mean.

I think I've probably got the same one and I wasn't using the biggest dies when I was doing 000 . Would probably work on the 000 lead crimp on ends.

The other issue with solder is that if the cable heats up enough, it could melt the solder and the cable can slip out

[@tcap7917]

Agreed but if it gets that hot theres another issue. Crimp and solder goves the best of both worlds. A quality crimp with a sealing heat shrink is all that is needed.

[@jeffclark5024]

It’s probably overkill but I like to solder after I crimp. I torch the lug and fill the cavity around the wire. Then heat shrink

[@lizardking667]

Soldering after crimp heats up the joint and can reduce the overall bond. I recommend to crimp or solder, not both.

@@lizardking667 idk man, I’ve never had a voltage drop problem or loose connection yet. I’d go further to say you couldn’t get that cable end off the wire if you tried, after I crimped and soldered it.

[@godblessthelessfortunate3175]

Harbor Freight should have included dies for 2/0 and 4/0 instead of the 14 and 7. I doubt anyone will find much use for 14 and 7. I need a 2/0 die. Has anyone found a source to buy replacement die accessories? If not, has anyone tried drilling out the less used dies to make 2/0 or 4/0? Obviously it will be round rather than hexagonal. The question is how secure will a round crimp be with a 16,000 lb crimp? Having heat shrink would stabilize it a tad.

[@baskinrobbins8713]

Solder joint is the best way to attach a ring terminal to wire. Crimp joints corrode internally & loosen up. But, if you can't handle a simple solder job & want problems down the road, go ahead & crimp. 4:59 "factory crimp on something" LOL A good crimping tool does a full circle crimp (AC lines), that thing you are playing with belongs in the trash can. Might as well use a pair of vise grips.

[@johnny0454]

@Baskin Robbins Not if crimped properly, which was not the case here as you know. I have a similar tool from China that works great and doesn't produce "wings" as long as the lugs fit the dies properly. I think the problem here is he's using metric lugs (mm2) with American dies (AWG) That's not the tool's fault.

I have one, had to re-machine all dies so they can't squirt out the sides, now they capture the fixture before crimping and they look/perform factory. Side squirt (wings) are not acceptable in a crimp and won't see one from reputable company.

1:14 soldering terminal is bad not because of the cost, but because of the metal fatigue... The connection will fail much sooner than a crimped connection, especially if there's vibration in the equation.
