haisstronicaCrimping Tool for Non-Insulated Open Barrel Terminals Receptacles,AWG 20-10 Ratchet Wire Crimper Tool,Wire Terminal Crimper HS-5327

I've noticed the newer crimp connectors with heat shrink sleeves don't seem to crimp as well with the old type of crimp that leave a narrow crimp mark. I thought I would try this since I bought an assorted set of the connectors with the shrink tubing. I'm not disappointed. The wider crimp seems to be working well as it is securely holding the wires in the connector where I could pull the wires out of the connector with the old style crimper. I'm not sure if it's a material difference in the connectors. They do seem much thinner than the old non-shrink sleeve versions. I'm please with the performance of this tool. The different heads are great because I do crimp different styles of connectors, i.e insulated and non-insulated terminals.

I like the performance of the haisstronica 6PCS Crimping Tool. I used the butt connector anvils to crimp some heatshrink-style butt connectors on 18 and 16 AWG automotive wire. The anvil's design preserves the integrity of the insulation around the butt connector so the electrical conductors stay dry under my truck.The ratcheting action ensures a full mechanical crimp and allows you to pre-clamp the connector in the jaws and insert the wire after, just before the final crimp. This helps when crimping in tight spaces.The tool is big. I had some trouble fitting it into the cramped spaces where my chassis wire bundles run under my truck.

This haisstronica crimping tool for heat shrink connectors is the latest addition to my arsenal — and, as usual, the quality and construction are excellent. They allow me to crimp various types of heat shrink connectors quickly and easily, since the jaws of this tool are forged with precision technology and can complete a secure crimp each and every time. The comfortable grip and solid ratchet action, as well as the ergonomically designed nylon, non-slip handle ensures comfortable and swift operation. For convenience, there is a quick-release lever on the inside of the handle that opens the jaws. When it comes to wiring tools, I will always rely on haisstronica 100%.

I have been fighting poor crimps for years when using the 'cheap' crimpers usually supplied with kits. Theses things work great so far. I am a bit concerned that they may not be heavy enough for heavy daily use but for the average DIY person these a great upgrade. The method for securing the different jaws seems a bit weak.I have yet to get a bad crimp.I do like that the set comes with a decent case so that the different jaws and handle all stay together.

(My review here was requested because HAISSTRONICA detected a return)I love these crimpers, they've worked so well, I ordered a second pair.There was a mistake in one of my orders where a different product was shipped instead of these crimpers. I believe that's why HAISSTRONICA thought there was a problem.No issues at all, simple Amazon Order fulfillment mistake, or oversight.Fine product.

I purchased this set specifically for my current need of a better non-insulated terminal tool than what I currently have and its worked exceedingly well. The overall construction and kit contents should cover many needs for most people- with other optional crimp jaws available, as needed. This is a 5-star product.

Bought: Haisstronica 6PCS Crimping Tool SetOk, Like many of you I have been using those cheap thin metal striper/crimpers that come in every electrical "kit" you ever buy. You can also buy those in stores and are fairly inexpensive, sometimes downright cheap. And to use them to crimp anything means hurting your hand from the pressure and that crappy thin metal.On to this tool and set: I paid $54.99 for this item and at time of review some 10 months later it is $49.99. That seems excessive or expensive however you know the old saying, you get what you pay for. Here you get so much more. It this set you get the crimping tool and 6 sets of dies. It says 6ps because die A is installed on the tool during arrival. The case it comes in is fairly cheap plastic but is more than enough for what you need. However I think the snaps that close it are poor. They are the standard molded on snaps that come with most things that wear over time and break and since they are molded on you cannot replace them. That's really the only con to this set. I opted for this set and not the one that comes with a screw driver because who doesn't already have a screwdriver in their tool kit? Anyways, the Tool feels great in the hand is VERY confrontable. The handle is molded plastic with rubber grips. Crimping pressure (how far down it crimps) is adjustable. The crimper uses a ratchet method so you don't accidently slip. This also lets you increase hand pressure a little at a time which is wonderful. When you hit the full crimp pressure the tool automatically unlocks releasing pressure. If in the event you cannot get full pressure to release there is a bar latch in-between the handles you can use to release the ratchet tension. The dies that it comes with are very wide for an even and professional crimp every time. Those cheap crimpers you get other places only crimp in a tiny spot which means sometimes you have to crimp then connector twice or more! Not with this tool, once and done!Changing dies is extremely easy. Just use a Philipps head screwdriver to remove two screws, one on the top die and one on the bottom. then change dies and replace screws. in the event you lose a screw, this set comes with two EXTRA screws! How awesome is that? This set also comes with almost every die you will need. I mostly use Insulated connecters so I mainly use die A but sometimes use others. I thought I'd never use the Solar connector Die but just recently actually used it and it worked wonderfully!Incase you forget what die is used for what, this little kit comes with a card with pictures of every die and the types of connecters each die is used for and wire sizes. that is EXTREAMLY helpful. The dies are each labeled A,B,C, ext. Also the case which holds the dies is also labeled in each slot for A,B,C, ext. So there is no confusing where each die goes or what they are used for.In conclusion, this set is well worth the money paid for it and is extremely helpful and comfortable to use. Not only that but it gives a good solid professional crimp every time. I have used this set hundreds of times. I have also installed 2 stereos in 2 different cars using this set and it was such a great tool to use. It not only made the job easier but it also made the job more solid and reliable. So please do yourself a favor and get this set, you will not regret it!

Very stout crimper for 6-10 ga terminals, Will self release after a full crimp. Good feature. I've struggled with release latches on smaller crimpers.
