A reliable everyday tool for clean, effortless cable cuts. Designed for copper wire and battery cables up to 1/0, making them a must-have for almost any electrical project.
Built for larger cables and repeated heavy-duty work. The ratcheting mechanism makes it easier to cut thick 2/0 and 4/0 cables with less effort and more control.
From precision wire stripping to heavy-duty cable cutting, the right tool makes every electrical job faster, cleaner, and more reliable. Explore dependable tools built for everything from small-gauge wire to large battery cables.
A dependable everyday tool for clean, consistent wire stripping. Designed for accurate results on both solid and stranded wire.
A versatile option for smaller wires, odd sizes, and jobs where standard strippers do not fit. A useful addition to any electrical tool kit.
Built for larger cables where precision and control matter most. Removes insulation cleanly from heavy-gauge wire up to 4/0 without damaging the conductor.
From small-gauge connectors to heavy-duty 4/0 cable, the right crimping tool makes all the difference. Explore dependable tools designed for clean, consistent crimps and secure connections—whether you’re working on a simple repair, a full wiring project, or a complete battery system.
My current favorite. The indentation and leverage are great. I can crimp up to 6 gauge, but I would not crimp anything under 16 gauge with them. Use the crimpers below for small wires.
For non-standard/non-insulated or waterproof jackets, use these. These are my go-to manual crimpers for small wires under 12 AWG.
Perfect crimp every time and this is my favorite model. Most people need this for 10/12 gauge wire.
From small-gauge connections to heavy-duty 4/0 cable, the right crimping tool makes all the difference. Explore reliable tools built for clean, consistent crimps and dependable connections every time.
A powerful battery-operated hydraulic crimper designed for serious cable work. With interchangeable dies and enough force for large-gauge connections, it makes clean, consistent crimps without the effort of manual tools.
The biggest difference between these models is the included die set. Most do not come with 4/0 dies, so if you need to crimp larger 4/0 cable, make sure to order the compatible dies separately.
Need to crimp cables larger than 4/0? This heavy-duty version is built for the biggest wire sizes, giving you the leverage and control needed for clean, secure crimps on oversized cable.
Not for everyone, but this thing is incredible. It is not cordless and it is very heavy, but you can use large industrial Temco dies with it and it works perfectly. If you have a workshop with a crimping station, this thing works great. The die set that comes with it is not for AWG!! It is in MM. Do not use with AWG lugs!
I do not like manual hydraulic crimpers. They take a lot of effort. But it will give you a fantastic crimp and I have tested it with my voltage drop test setup. This one worked as well as the more expensive ones. The major downside is that it takes a bit of effort to do every crimp, but if you’re only doing one system, this is a great option.
I still love this thing. Super fast and easy to use, but these days I am using electric only. I have crimped thousands of cables with this crimper, but electric is just better.
I tested cables made with this crimper and even though the crimper looks perfect when you cut it open, it was not! The resistance was a lot higher than the other crimpers. I do NOT recommend using this one. I understand this might be all that people can afford sometimes, so I will leave it here. But I am not using this crimper any longer.
Crimps 8 AWG to 4/0 Battery & Welding Cables
If you are working with DC or AC electronics, you need a torque wrench AND screwdriver. There are lots of budget options on the market today, but it is crucial to tighten copper and aluminum to the proper torque spec. If not, the connection will loosen with time and can cause a fire. I have a lot of torque wrenches and screwdrivers, these are my favorites:
Most terminals are rated in Nm or In Lbs. This torque wrench is perfect for this application. The quality is fantastic for the price and I love it.
There are a lot of these available, but this is the original. Best bang for your buck and I still use mine a lot. Easy to adjust and just works. The head holds on to bits nicely and if you need extra torque, the included attachment helps a ton.
Want to spend some money? This is the Fluke of torque screwdrivers. Made in Germany and a perfect tool. No better than the one above it in my experience, but the bits and locking mechanism are fantastic. It is designed to work with electrical connections, and once you have it, you will reach for it more than the others. Solid device.

I have not been able to kill this PSU. It is great for charging lithium ion batteries w/ BMS. Just ensure the output voltage is set before you connect a battery. If you want to spend more, expect to spend $400+. This one works great for manually charging individual lithium cells, and higher voltage batteries.
My dad and I have broken a lot of tools over the years. Milwaukee are the only ones that hold up. I highly suggest spending the extra money and sticking to the Fuel series Milwaukee. It will save you money in the long run.
My favorite small impact gun. If you do not have it, buy it. You will use it every day. This is the one you need if you are doing electrical work. The other impacts they make strip everything out. This thing is perfect for metal screws and more.
Cut through walls, pipes, wires and anything you wish. Great tool. You can also open up battery cases and see what’s inside, and how badly you got ripped off by an unknown seller on AliExpress.
