List of materials

  • drill 10 mm;
  • bolt M12;
  • long nut M12;
  • vehicle tie rod end.

Production process

It is necessary to saw off all unnecessary parts from the steering tip.

Nutbreaker: purpose, use and types of tools

When dismantling and replacing parts, you have to deal with rusted and stuck nuts. Unfortunately, unscrewing such fasteners using a key is quite problematic. One of the easiest to use and most effective methods is to disassemble bolted joints using a nutbreaker.

Do-it-yourself screwdriver

Types of nutbreakers

Mechanical manual

Suitable for car enthusiasts and household needs. The forces generated by the tool are enough to unscrew a soured bolt or stud. It is inexpensive, sometimes they make it themselves.

Sold in stores separately or as part of sets of 2-3 items. Prices for a mechanical nut breaker start at 200 rubles. and reach 3000.

The main disadvantage of the device is that working with it requires significant physical strength, and therefore the maximum diameter of the nuts is limited to 27 mm.

The design and operating principle are extremely simple. The tool is a steel ring of sufficient thickness and rigidity with a welded handle pipe through which the cutting element enters the ring area.

Do-it-yourself screwdriver

The cutter is connected to a bolt that pushes it forward through a steel ball bearing.

Hydraulic compact

Such a tool looks little different from its mechanical counterpart. During the operation of a hydraulic nut cutter, the screw is also turned, but the pressure is not transmitted directly to the cutting surface, but through a hydraulic booster, due to which the person strains less. A compact hydraulic nutbreaker develops forces of up to 5 tons and costs in the range of 2000–7000 rubles.

Hydraulic manual

In appearance, a hydraulic manual nutbreaker is similar to a plastic grease gun. The tool has two handles - a holder and a hydraulic lever.

The piston system is responsible for increasing the force in the device, thanks to which it is possible to obtain a significant 35 tons. A hydraulic nut costs more than 9,000 rubles; there are models for 30,000.

Such nut cutters find their application in construction and other professional fields. The undoubted advantages are high power and independence from external energy sources.

Hydraulic with separate drive

This type of nut cutter is connected to an external power source. Pumps that create pressure operate on electricity, gasoline or the muscular power of a worker. The hydraulic nut-breaker develops enormous force with the help of an external drive; nuts up to M36 are cut inclusive.

Application – construction, railway transport, industry.

Do-it-yourself screwdriver

The price of the nut cutter itself is about 15,000. The cost of the tool together with the drive reaches 500,000 rubles. Choosing an electric pump saves about half this amount, but makes the installer dependent on the network.

The nut hammer is intended for removing nuts that are stuck, rusted or with broken threads. In this case, the bolt remains undamaged. Different models of nut cutters are widely used in auto mechanics, construction of buildings and engineering structures, fastening of industrial equipment, power plants...

According to the principle of operation, the tool is similar to a chisel, only it cuts the nut, creating constant pressure of the cutting edge on its surface, without impact. The ring holder ensures a secure grip of the fastener.

Device and characteristics

Regardless of the specific model, the nut has the following parts: body, drive, cutting element.

The body of the nut splitter, like a spanner wrench, is installed on the nut, for which it is made in the form of a half or full ring. The diameter of the hole determines which nuts the tool can work with. The handle with the screw in mechanical models also serves as a stop for the cutting part. The drive creates the force necessary for cutting metal.

Do-it-yourself screwdriver

Due to the fact that each tool has an acceptable range of nuts, it makes sense to take a set of nut breakers when purchasing. So the desired option will always be available.

Material

The main material is steel, and for the cutting component - more durable and wear-resistant alloy metal grades. The handles are covered with chemical-resistant rubber for greater comfort and a secure grip, even with oily hands.

Dimensions and weight

The dimensions and weight of the nutbreaker vary from model to model and depend on the working range of nut diameters. Simple mechanical devices about 100 mm long weigh approximately 200 g. Hydraulically reinforced nut splitters for nuts up to 24 mm can weigh up to 4 kg. In terms of dimensions, this hydraulic nut will be similar to a car jack.

When working, you should adhere to the following rules:

  • Do not adjust the nut by hand during dismantling.
  • Be sure to wear safety glasses and gloves before starting work.
  • Control the location of the cutting part; its movement should go towards the center of the bolt. Only minimal deviation is acceptable.

Tips for choosing

To select the optimal nut breaker, they focus on the list of future tasks.

The buyer must be clearly aware of the difference between domestic and industrial use, understand the diameters of the fasteners and understand what forces are required from the tool, and whether a mechanical drive will be sufficient. For those who purchase a nut cutter for household tasks, it is recommended to adhere to the following rules:

  • Before purchasing, dimensions are taken from the nuts to be removed; it is also important to measure the free working area around the nut if it is limited in some way. This way you can choose the right screw.
  • If the tool will be used very rarely, for example, the need to cut off fasteners is one-time in nature, and when the nut will be needed again is unknown, it is better to buy an economy class product. In this category, STAB and FIT are considered worthy representatives.
  • It often makes sense to choose a set of several tools, especially if the overpayment is small. This type of purchase is more forward-looking.
  • You should avoid purchasing nutbreakers from unknown ones; as a rule, they better monitor the quality of their products.
  • If you have the tools and the proper skill, you can make a nut cutter with your own hands.
  • List of tools:
  • welding machine;
  • bench vice;
  • lathe (optional);
  • drill and bit;
  • grinder and grinding wheel for metal;
  • threading device;
  • grinder.

How to make a nut with your own hands

If you have the tools and the proper skill, you can make a nut cutter with your own hands.

List of tools:

  • welding machine;
  • bench vice;
  • lathe (optional);
  • drill and bit;
  • grinder and grinding wheel for metal;
  • threading device;
  • grinder.

First, find the base for the nut cutter ring. Unnecessary spare parts with thick steel circles, for example, a steering wheel tip, are suitable. If these are not available, the element is made from metal round timber on a lathe. The center of the hole being made is mixed by placing a small plate under one of the cams. The hole size is checked against the maximum nut that the tool will pierce. When a recess of sufficient diameter has been obtained from the round timber, a thick ring is cut off. Its width should be enough to weld the handle and drill a through hole to accommodate the cutter.

A hollow steel rod is suitable for the handle of the nutbreaker; you can use part of the same steering tip. The advantage of this option will be the finished internal thread. Alternatively, the handle is made on a lathe by drilling through a metal rod and then applying the threads.

The ring and handle are welded. The workpiece is fixed in a vice and a hole is drilled in it, connecting the cavity inside the handle and the working space of the ring. Sometimes part of the circle is cut off to create a C-shaped nut.

For chisels, choose durable metal rods such as a drill, tap or rubber. The required sharpening is created on a sharpening machine.

The two remaining important parts are the bearing ball and the bolt. The cutter is placed in the frame of the nut cutter, then the ball, then the bolt is tightened. Sometimes, for additional fixation of the chisel, I drill a hole in the handle assembly and screw another one in there. If necessary, grind with a nut, giving the handle the desired shape.

Wrench. Let's move on to radical measures!

Do-it-yourself screwdriver

How do you usually unscrew bad nuts?

Until recently, improvised means were used to unscrew problematic fasteners (boiled, rusted nuts, as well as those with licked edges).

Gentle ways:

  • Moisten the threaded connection with kerosene or penetrating lubricant such as WD-40. This procedure requires a long time, since one time is not enough and requires exposure for several hours.
  • Heat the nut using a gas torch or heat gun.
  • Weld another, larger nut to the one being unscrewed, and then try to unscrew what happened using a larger wrench.

Surgical methods:

  • Move it from its place or cut it with a chisel. To do this, you need to have a steady hand and an accurate eye. A minimal command of profanity will also come in handy after you hit your hand with a hammer.
  • Saw off with a hacksaw or grinder, if you have access.

As a result of surgery, the bolt or pin will also be damaged.

Homemade impact wrench from an old spanner

Often you have to deal with a non-standard situation when you need to unscrew a nut, but it doesn’t want to turn at all - it’s rusty. As a rule, a regular open-end or socket wrench will not help in this situation.

Do-it-yourself screwdriver

We have to resort to more radical and effective methods. For example, some craftsmen use a grinder with a cutting disc, while others pick up more accessible tools: a chisel and a hammer. However, the first method is too noisy, the second is inconvenient.

6479th place in the ranking of bikeposts Good afternoon, I would like to touch on the topic of one seemingly (and by name) useful tool - a Nut Cutter. A little background.

It all started with the fact that the nuts on my cylinder head were licked off, one was on the side and, in principle, it would not have been difficult to cut it off, but I wanted to preserve the thread, and I didn’t want to destroy the head...

After surfing the Internet for a long time, I read a lot, didn’t understand anything, and eventually decided to write an article. There are two types of nut cutters: 1. Hydraulic 2. Mechanical And so on in turn.

Do-it-yourself screwdriver
The hydraulic nut cutter works like this: you pump the pump and the liquid pushes the blade, which in due course cuts the nut. I will provide a video on how it works.

I liked the hydraulic nut cutter, but I didn’t manage to try it, I couldn’t find it in my city. So I have nothing more to say about him. Now I’ll tell you about what I was able to experience. This is a mechanical nut cutter, it is simpler. You twist the bolt and it moves the blade.

I went to the auto parts store and bought it, and then headed to the garage. I put it on the nut and began to twist the bolt, at first everything went well, but as soon as the blade hit the nut, then with the next turns of the bolt the blade began to crumble. But don’t despair, I haven’t lost faith in the tool, I just bought a cheap nut cutter for 200 rubles and when I got home I started flipping through RuNet and realized that it’s better not to save money here and a normal nut cutter will cost 1500-2000 rubles. (so that’s my mistake, I bought it from China) Using a nut cutter, I still couldn’t remove the nut, so I had to use the old-fashioned methods of heating it and tearing it off or demolishing it with a chisel and hammer. Well, I started to heat it up and heated it almost to red, I started to pick it, but it didn’t work (then I tried it again). But in the end I gave up on it all, took a chisel and a hammer, and off we went. After 12-20 minutes of chiselling, it took so long because one nut was near the timing chain tensioner and it was simply out of reach. Here is the result.

Do-it-yourself screwdriver
Conclusion: 1. A nut cutter is a useful tool, but if you are going to buy it, then buy a normal one. (preferably the company in the video) 2. If you couldn’t or didn’t want to buy a nut cutter, then heat it up and try to tear off the nut (bolt). 3. And if the nut (bolt) has become completely round, as in my case it was, then use a chisel and a hammer, just don’t overdo it and break the bolt on which the nut is on or tear off the bolt head (if the bolt head is rounded, then it’s better to weld the nut on top and try to pick for her). PS Better yet, try not to lick the edges on the nuts and bolts.

Nut cutter, nut splitter - will solve the problem of problematic nuts

Anyone who repairs cars has probably more than once encountered a situation where a nut is soured or rusty, and it is not possible to unscrew it, since its edges are licked off. As a rule, the solution to the problem is a grinder with a cutting disc.

The nut is cut bluntly, but there is a possibility of damage to the stud, which can complicate the repair of the car. Considering that not everywhere there is full access to the required nut, then sometimes you have to spend a lot of time sawing it with a simple hacksaw blade.

To ease your plight, a special device was invented called a nut cutter (some also call it a nut cutter). The meaning of this device is as follows: we put one part of it with a cutter on the nut, and begin to tighten the rod.

Under the action of the generated force, the cutter cuts the nut on one side. After this, we move the nut cutter to the other side of the nut and do the same procedure, after which the nut falls apart into two parts.

For more details on the operating principle of the nut cutter (gacokol), see the video presented.
