Professional set of tags and plaques Autodelo: choice and features of operation

In the arsenal of every motorist engaged in self-service vehicle, sooner or later there is a need to restore or create a new threaded connection. Failure of thread in the block of cylinders, damage to the studs of the exhaust manifold or the need to install additional fasteners are standard situations that require high-quality special tools. This is where professional comes to the fore. tag-and-plateIt allows you to solve complex tasks right in the garage, without contacting specialized services.

Domestic brand Autodela It has established itself as a manufacturer offering an affordable solution for a wide range of tasks. Their kits often become a compromise between cheap Chinese consumer goods and expensive European counterparts. However, in order for the tool to really justify the investment and allow you to perform the work qualitatively from the first time, you need to understand the intricacies of its design, marking and proper application. The key factor of durability of the tool is not only the steel grade, but also the correct preparation of the hole before the start of work.

In this material, we will analyze in detail the configuration of sets, the technology of cutting threads and typical errors that even experienced masters make. Understanding the physical processes involved in cutting metal will help you avoid breaking down an expensive tool and damaging your car parts. Deep immersion in the theme will allow you to confidently choose and use metalworking equipment for any task.

Anatomy of the set: complete set and types of tools

Standard case from the manufacturer Autodela It is usually a compact plastic organizer, inside which are located the cells for storing each element. This system prevents the loss of tags and ensures their safety from mechanical damage during impacts. Inside, you will find not only the cutting elements themselves, but also the collars needed to create torque.

The basis of the set is the tags designed for cutting internal threads. They are divided into several types depending on the task: rough, medium and clean. In sets for garage use, universal or two-pass options are most often found, which speeds up the process, but requires attention to the state of shavings. Plaques, fixed in the plaster, serve to form external thread on bolts or studs.

Special attention is paid to the material of manufacture. For automotive work, where you often have to face hardened steels or, conversely, viscous aluminum alloys of the engine, the hardness of the cutting edge is critical. High-speed steel tool HSS High Speed Steel is a standard that provides a balance between strength and the ability to hold sharpening at high temperatures.

• 🛠️ Tags: The main cutting element for internal threading, often marked with risks on the tail.
• 🔩 Plaques (round and cut): They are designed for external threads, require accurate centering.
• 🔧 Gates and placeholders: provide force transfer and fixing of the tool in the working position.

What are the differences between clean and clean stains?

Black marks (often designated by one risk or the number 1) have a more pronounced cone of the entrance part, which allows you to remove the bulk of the metal. The pure ones (three risks or the figure 3) have a minimal cone and serve to calibrate the hole and obtain a smooth surface of the thread. Using only a clean gauge to the full depth of the hole can lead to its failure due to increased torque.

Technology of cutting threads: step-by-step instructions

The process of creating threads requires strict adherence to the sequence of actions, otherwise the result will be unsatisfactory, and the tool may fail. The first step is always to drill the hole under the gauge. The diameter of the drill must correspond exactly to the diameter of the thread being cut, for which there are special tables of relations.

After drilling, it is necessary to remove the beam from the edge of the hole. This action facilitates the approach of the gauge and provides perpendicularity of the thread axis relative to the plane of the part. Ignoring this stage often causes the meter to start “walking”, creating a skewed thread that is almost impossible to fix.

Direct cutting is performed by translational-rotating movements. For each half-turn of the collar forward, you need to make a quarter of a turn back. This technique, called "breaking chips", allows you to crush metal shavings and remove it from the grooves of the tag. If you neglect this rule, the chips will compress, create excess pressure, and the tool will jam or break inside the part.

⚠️ Attention: When working with aluminum alloys (for example, the cylinder head) it is strictly forbidden to use dry cutting or engine oil. Aluminum has high adhesion and quickly "sticks" to the cutting edge, which leads to bullies. Use special emulsions or kerosene.

Marking and decoding of symbols

Understanding the marking on the tool’s tailings allows you to instantly determine its purpose and material. On the brand's products AutodelaLike most high-quality tools, an alphanumeric code is applied. For example, a designation M6 indicates a metric thread with a diameter of 6 millimeters, and M12x5 It speaks of a thread pitch of 1.5 mm.

Also on the surface can often be found marking steel. Designation P6M5 (or analogue) HSS) indicates high-speed steel with the addition of tungsten and molybdenum. This material can withstand heating to 600 degrees Celsius without losing hardness, which is critical when working with hard steels at high speeds, although in manual mode, heating is less likely to be a critical factor.

Color encoding or notches on the tail helps to quickly identify the tag number in the kit. Usually one notch means a rough gauge, two - the middle and three - the clean. In universal sets, only one tag can be used, which combines the functions of all three, but the resource of such a tool during intensive operation will be lower.

Designation	Type of thread	Diameter (mm)	Step (mm)	Application
M6	metric	6.0	1.0	Fastening of small details, brackets
M8	metric	8.0	1.25	Standard pallet bolt, lid
M10	metric	10.0	1.5	Fixing of attachments
M12	metric	12.0	1.75	Studs of the exhaust manifold

Lubricant-cooling liquids (COL): choice and application

Many motorists underestimate the role of lubricant in cutting threads, relying on motor oil or solidol. This is a gross mistake that reduces the life of the tool at times. Special services are needed for quality work JOYNot only do they reduce friction, but they also remove heat and also contribute to better removal of shavings from the cutting zone.

Different materials require different compositions. When working with steel and cast iron, sulfoemulsols or special pastes with sulfur and chlorine content are excellent. For non-ferrous metals such as aluminum and copper, it is better to use kerosene, white spirit or specialized alcohol-based sprays that do not cause corrosion and chemical interaction with the metal.

The use of aerosol lubricants, such as WD-40It is permissible only in extreme cases, since they have low viscosity and quickly evaporate, without providing the necessary film of strength in the contact zone. The ideal option for a garage is to have a small bottle with a universal threaded paste that does not drain from vertical surfaces.

Common Errors and How to Prevent Them

The most common mistake is a violation of the perpendicularity of the entry of the detector into the hole. If the tool enters at an angle, it is almost impossible to fix this in the process - the thread will be skewed, and the meter will most likely break. To prevent this, use special guide sleeves or tiles with emphasis, especially when working with long tags.

Another common problem is trying to cut the thread "dry" or with insufficient lubrication. This leads to overheating of the cutting edge, release of metal tools and its rapid blunting. Visually overheated tag changes color (run), after which its use becomes meaningless.

The use of worn or blunted tools to restore threads in responsible nodes is unacceptable. Blunted tag It does not cut the metal, but presses on it, creating a rivet and distorting the profile of the thread. As a result, the bolt can twist with great effort or, conversely, not hold in the hole, which in vibrating conditions of the engine can lead to serious consequences.

⚠️ Attention: Never try to forcibly swipe a jammed meter with a long handle collar, creating an excess lever. This is guaranteed to cause the tailing to break. It is better to clean the grooves, add lubricants and act in short, neat movements.

Tool care and storage

After completion of the work, the tool must be carefully cleaned of metal shavings and lubricant residues. For cleaning, use a hard brush and solvent. The remaining shavings can cause corrosion or damage cutting edges during storage. After cleaning, it is recommended to wipe the tags and plaques with oily rags to create a protective film.

Store the set should be strictly in a regular plastic case, fixing each element in its cell. Chaotic storage in a box with keys (“in a pile”) leads to chipping of the carbide plates and blunting of the edges on other tools. The plastic case also protects the tool from moisture, which is the main enemy of tool steel.

Periodically check the condition of the cutting edges. If you notice that the tool requires increasing effort to work or leaves a “shaggy” thread, it may be time to sharpen or replace. Cheap kits Autodela Often do not involve professional sharpening in garage conditions due to the complex geometry, so they are easier to replace when worn than to try to restore.

Frequently Asked Questions (FAQ)

Can I use a metal tag to cut the thread in plastic?

Yes, you can, but with caution. Plastic is less durable, and a standard tag can bite the material, especially if it is viscous. It is recommended to use high-angle sharpening or specially designed for plastic, and to work at very low revs (manual) and with minimal pressure.

What if the squirrel breaks inside the hole?

There are several methods: the use of extractors (special twisters), spark discharge (requires special equipment) or neat knocking out the residues with a core, if the design of the part allows. In some cases, chemical etching helps, since tool steel and steel parts can have different chemical resistance.

What is the difference between metric and inch carvings in sets?

Metric thread (designated M) has a pitch in millimeters and a profile angle of 60 degrees. Inch (denoted by numbers and fractions, for example) 1/4") measured in inches and often at an angle of 55 degrees (pipe) or 60 degrees. They are not interchangeable, and trying to screw a metric bolt into an inch hole will result in the thread breaking.

Do I need to lubricate the drill before drilling the hole under the thread?

I will. Drilling the hole is the first and most important stage. If the drill overheats or blunts, the diameter of the hole will be broken, and high-quality thread will not work. Use the same lubricant as for subsequent slicing.
