What are the nozzles for multi-tool

One of the most interesting novelties of recent years in the market of household and professional tools has become a renovator or multitool. It is an electrically driven device capable of performing a large number of technological operations required in the process of construction, repair and processing of solid materials. Versatility is given to it by interchangeable nozzles of various shapes and purposes, performing oscillatory movements with high frequency and low amplitude of movements. This article is devoted to their brief description and comparison of functionality.

The best approach to the choice of nozzles

Nozzles for multifunctional tools in the process of working the main load, so their choice should be approached seriously and carefully. Usually one or another number of them is present in the set of the sold renovator, which can be mains or battery. If the set of nozzles sold at a reasonable price along with the multitool is too large, then this indicates a low quality of their production. It is better to purchase a unit of a well-known brand with several main cutters, and then purchase those that you really need in your work. In this case, the design and execution of the part must correspond to a specific purpose and the strength characteristics of the material being processed.

Do not be lazy to ask the seller accompanying documentation and make sure that the product has the appropriate markings.

Since the nozzles for the renovator function in the high-frequency vibration mode, they must be securely fixed in the fixing unit of the working head of the instrument. To do this, in its case there are curly cuts, which for different manufacturers of multitools may not match the form. It is necessary to pay attention to this when purchasing. Mounting can be done with:

• hex key;
• special clamp quick fix.

Exist universal adapters, allowing to apply products of different manufacturers. The differences between the nozzles for the multitool relate to the shape of the part, the used base material and surface coatings, the cutting edge device. Their design is best suited to perform a strictly defined type of processing and in most cases allows you to work in inconvenient places or in cramped conditions. Along with the versatility of the tool, this is its main advantage.

Main types of nozzles

Due to the oscillatory movements with sufficient strength of the nozzle, it is possible to perform various types of operations on materials with moderate hardness and even on metal. The design of the cutters is varied, but the details of the optimal form for each type of work have the maximum practical application.

Scrubbers to remove dirt

Scrapers are used for cleaning surfaces from old coatings and bonding materials, which include:

• paint;
• glue;
• sealant;
• foam;
• cement spray and other contaminants.

They have a flat or curved shape with a straight or arcuate working edge. After this treatment, there remains a flat surface that can be prepared for a fine finish.

Diamond coated cutting discs

This nozzle has a high surface hardness. With its help you can:

• clean the joints between tiles and panels;
• embroider cracks;
• remove nodules of cement;
• cut concrete, stone, ceramic products.

It is not designed to perform a large amount of work, for which it is better to use a specialized high-performance concrete tool.. But for a one-time stripping and cutting in hard-to-reach places such a disc is best suited.

Grinding plates

Grinding plates are used for:

• cleaning surfaces from contamination and their rough alignment;
• fine grinding;
• polishing products.

The type of treatment depends on the grit of the abrasive layer, which can be applied to the part itself, but more often it is used for this. sandpaper sheets. The form of the plate has elongated protrusions that allow full grinding of the sections along the walls and in the corners.

Serrated circular blade with serrated edge

The nozzle of this form is applied as a saw. It is made of high quality alloy steel. With it, you can perform accurate and accurate cut by:

• wood;
• plastic;
• other construction materials, including non-ferrous metals and low-grade steel.

Such a disc makes cutouts in drywall, trim flush protruding elements, process the ends of the workpieces or make slanting edges.

Sometimes used for multitool straight or figure saws elongated shape, allowing to cut in hard to reach places. If in a specialized store there was no nozzle of the desired configuration, you can try to make it yourself.

Production of a saw nozzle for multitool

As a blank you can take hacksaw for wood with a wide saw blade. It will make several long-lasting nozzles, because the saws are always made from high-quality steel. After applying the markup, the contour of the part is cut using an angle grinder.

It is hardly possible to accurately reproduce the mounting holes of a complex configuration for installation in the renovator at home, so it is easier to cut off the corresponding section from the old nozzle. To connect it with a new plate, two holes with a diameter of about 2 mm are drilled in it.

Doing the same in the hardened metal of the saw will be more difficult. Additional will be required steel tempering operation, which consists in heating the gas torch from the back of the workpiece to a crimson color with slow cooling in air. Then in it, after marking, two mating holes are drilled with the same drill. Making sure they match exactly, they increase the diameter of all four holes to 6 mm.

If you want to curved tipBending parts with a vise and plumbing tool. After connecting them with short M6 bolts with counter nuts, the multitool file is ready for operation.
