Drill nozzles for various purposes for work in a home workshop
Drill attachments have turned this tool into a universal assistant. Thanks to these removable devices, it is possible not only to make holes, but also to cut building materials, mix mixtures evenly, and also to process the surfaces of products made of plastic, wood, metal and concrete. This article describes the main types of nozzles, their characteristics and scope of application.
Drill attachments: purpose and classification of removable devices
The use of removable devices allows you to turn an ordinary drill designed to form holes into a universal tool. The nozzles significantly expand its functionality, eliminating the need to buy highly specialized equipment. Even for the most ordinary drill, the choice of nozzles presented in stores is so extensive that there is not one, but even several classifications.
On sale you can find nozzles for performing a variety of tasks:
- tightening of fasteners;
- milling machines;
- drilling holes of various sizes;
- polishing, etc.
If you use the nozzle and drill correctly, you can get almost the same quality of processing as with a highly specialized tool. According to their purpose , these products are divided into the following categories:
- nozzles for cutting sheet metal;
- crowns and devices for drilling holes;
- nozzles with angular design;
- devices for grinding and polishing various surfaces;
- milling cutters for metal and wood processing;
- attachments are removable;
- devices designed for sharpening, mixing and other tasks.
The main types of polishing and grinding nozzles for a drill
Polishing and grinding nozzles are the largest category of removable devices for drills. They all differ in the material of manufacture, in shape and purpose, although they are attached to the tool in the same way. For this purpose, a special cylindrical rod is provided in each nozzle. It is fixed in the tool holder.
The most common types of polishing and grinding drill bits:
- end faces;
- fan – shaped;
- polishing in the form of soft disks.
These are only the main types of attachments, there are other types of removable devices for grinding. Some of them have a special design that allows processing products with complex shapes.
Pay attention! When choosing removable nozzles for the tool, it is necessary to take into account the requirements prescribed in the instructions. For each type of components, a certain speed (number of revolutions) and power of the drill are provided.
The expansion of functionality is the main, but not the only advantage of removable devices. The nozzles allow you to perform various surface finishing works and at the same time do without expensive highly specialized equipment.
Advantages of drill bits for metal and wood in comparison with highly specialized tools:
Removable devices also have disadvantages:
If a drill with a nozzle will be used to perform a small amount of work, then the listed disadvantages can be considered insignificant.
Types of drill attachments for grinding wood and metal: classification by type of material
The scope of application of removable devices for grinding is very extensive. With the help of drill attachments for stripping metal, you can remove remnants of old paint, traces of rust and other contaminants from the surface. Such work is usually carried out at the preparatory stage before painting. Some nozzles are used for stripping metal elements after welding.
Grinding nozzles can also be used:
- for polishing metal, glass and plastic surfaces, as well as paint coatings;
- processing of edges on glass;
- grinding of surfaces in hard-to-reach areas of products;
- removal of burrs and other defects from the surface.
According to the type of material , there are three types of grinding and polishing devices:
Sandpaper is the most common material with abrasive properties, which is used for stripping and grinding surfaces. Such paper can have different grain size and degree of roughness, which allows you to choose the best option for roughing and finishing products. The nozzles on the drill for grinding wood, consisting of an emery cloth, can be polished on the surface.
The group of devices made of soft materials includes nozzles made of foam rubber, vinyl, felt, etc. They can be successfully used to remove corrosion and rust from the surface, as well as to remove putty from walls and clean the car body from the primer.
Useful advice! The felt nozzle will allow you to polish the paintwork on the car to a shine.
Grinding stones are a special type of abrasives, which is suitable not only for cleaning the surface, but also for removing various defects from it. Such devices can be used as drill attachments for grinding metal, ceramics, concrete and glass.
Overview of drill attachments for grinding surfaces
The cup nozzle is made in the form of a bowl, on which the bristles are fixed. Such devices have a high degree of rigidity, since their fibers are made of plastic or wire. They are usually used as attachments to a metal drill to remove corrosion, paint residues, solid contaminants and slags formed during welding.
Disk devices have a similar design. However, in such drill attachments, the brush is directed to the sides, not forward. You need to use them very carefully. If you do not adhere to the technology, you can damage the treated surface.
Plate nozzles are made of elastic material. The edge part of the product has flexibility, so that the abrasive material can be brought to the treated surface at different angles, which allows grinding even in the most inaccessible places.
A circle of sandpaper is attached to the plate nozzles in different ways, for this purpose can be used:
- adhesive composition;
- velcro (Velcro fastening);
- double-sided tape;
Fan devices for drills resemble a lady’s fan in appearance. In the center of the nozzle is a small disk. Sandpaper is fixed on it. Moreover, it is not made in the form of a solid canvas, but in the form of petals with an abrasive coating. The design of the fan nozzle is very mobile. During use, it can change its shape, adjusting to the relief of the treated surface. With the help of a fan nozzle , you can process:
- internal surfaces;
- hard-to-reach places;
- surfaces with complex relief.
Drum-type nozzles resemble the design of fan devices, only their petals are located perpendicular to the plane of rotation of the inner disk. They are designed for grinding hard materials. With the help of drum nozzles, the edge of the glass is cleaned after cutting.
The end devices work on the same principle as the grinding wheel. At the end of the rod they have an abrasive material fixed, which can have a different shape:
- cones , etc .
The end nozzles are small in size, which allows not only to balance the device, but also to use it to get to hard-to-reach areas.
Useful advice!Cutting and abrasive discs from Bulgarians can be used for disc attachments. With the help of an adapter with a centering drill, they can be securely fixed to the shaft.
Features of drill attachments for surface polishing
Nozzles designed for polishing surfaces are in many ways similar to grinding ones. The difference between these devices is only in the abrasive. The polishing nozzles use soft materials, thanks to which a finer surface treatment is carried out.
Polishing devices are made in the form of a disk made of soft material. They have a soft filler attached to them, for example, felt, foam rubber or felt. According to the degree of softness , polishing nozzles on the drill are:
- medium hardness;
- super soft.
In addition, polishing nozzles vary in size and shape. Such a large assortment allows the buyer to choose the best version of the tip, which is ideal for processing a particular surface.
The choice of the tip depends on the type of work to be performed with it. For example, cone-type nozzles are designed for polishing holes. For the same purposes, thin cylindrical devices can be used. Petal nozzles are better than others to cope with the processing of hard-to-reach places on relief products. Cup nozzles are useful in cases when you need to polish the coating.
Overview of drill bits on wood: drills and crowns
Drilling holes is the main function of a drill, for which a huge selection of removable devices is provided, presented in a single form or in the form of whole sets. The most common types of nozzles used for these purposes:
- Forstner drills;
- feather drills.
Metal crown: types, sizes, methods of application
Technical design and method of application. Types of cutting edge. Nozzles for drilling Bosch, “Anchor”, “Bison”, Fit. Proper use of the tool.
The Forstner drill has wide cutting surfaces located on the sides. A tip is provided for centering this tip. This type of nozzle is used to form medium and small holes in wood. At the same time, the tip does not pass through the material. The presence of the tip allows you to achieve high accuracy when creating holes for mounting hinges.
Feather drills are designed to make wide holes, the diameter of which can reach 6 cm. These nozzles make it possible to install fittings in wood slab materials and even in an array. Such drills are equipped with wide side feathers and a centering point. Thanks to this design with a flat shape, the recess is accurate, while the depth of the hole is limited.
Crowns are nozzles with a complex design designed for sampling material. The cutting surface of these tips has a characteristic profile, it is wide and has a high margin of safety. Crowns work on the principle of an incisor, and in some cases – several incisors. They are used to create holes whose diameter can reach 10 cm. A drill bit is installed in the center of the tip. With its help, the first hole is set, which centers and directs the nozzle. Crowns can be used not only on wood (fiberboard, chipboard, array), but also on metal and concrete.
Pay attention! When choosing a nozzle of any type, it is necessary to take into account the size of the electric drill chuck on which it will be installed.
Depending on the configuration, the drills can be used as drill attachments for concrete, wood and metal. Tips with a high margin of safety are called pobeditovye. This group of devices includes attachments designed for shock and vibration equipment.
Mixer and vibrator for concrete: drill attachments for construction
The construction of monolithic walls and foundations has its own characteristics. A high-quality result can be achieved only if there are no voids when laying concrete. For this purpose, special mechanisms called vibrators or seals are used. There are many varieties of these devices, which differ in the principle of operation (the method of vibration transmission) and the type of drive.
Vibratory nozzles for a drill or a hammer drill belong to the category of portable or manual devices that are connected to a power tool. The construction of concrete seals includes the following components:
- connecting drive;
- the engine (in this case, it is an electric drill engine).
The tip creates high-frequency mechanical waves and transmits them to the concrete mixture. The design of a vibrator or a vibrating hammer can be diverse, but their purpose is the same. The tip is connected to the electric drill motor by means of a drive, which can be metal or flexible, short or long. The outer diameter of flexible products reaches 1.5-3.5 cm, their length varies between 0.5-15 m.
Advantages of using a vibrator:
- excess air and moisture are removed from the concrete mix;
- improves the quality and strength of concrete by eliminating voids;
- the forms are filled in evenly;
- the mixture is homogeneous and fluid;
- the solidification period is shortened;
- the service life of the finished structure is significantly increased.
In construction, drill mixers are also used, designed for mixing solutions with different degrees of density, for example, concrete, coloring compound or wallpaper glue.
Pay attention! The configuration of the removable device is selected taking into account the consistency of the solution, otherwise the mixture will be heterogeneous.
Advantages and overview of drill attachments for cutting wood and metal
Devices for cutting metal or wood are used in cases where it is not possible to perform this procedure in another way. In addition, they will be useful if heating of the sheet material during cutting is undesirable.
Advantages of nozzles over a grinder:
Overview of drill attachments for sheet metal cutting
Three types of nozzles are used for cutting metal sheets: “Cricket”, “Scissors” and “Beaver”. Each of them has its own characteristics, structure and is designed for cutting a material of a certain thickness.
In the process of using the “Scissors” nozzle on the drill, the rotation of the chuck on the tool is converted into reciprocating movements. As a result, a special matrix knocks out a strip in the metal and separates the material. The thickness of this line is 3.1 mm. With this method of cutting sheets, the cut is obtained with high quality and smooth. The “Scissors” nozzle allows you to completely abandon the refinement of edges on metal or minimize it.
The Beaver nozzle works in a similar way, only with its help it is possible to make both straight and curved cuts, the minimum radius of which is 12 mm.
The nozzle for the drill “Cricket” can be considered a universal device, since it can be used to cut not only metal, but also plastic sheets. In some cases, it can be used for cutting profile products. The device is equipped with two cutting heads, providing a perfectly smooth cut.
A table showing the restrictions on the processing of the material by thickness:
|Type of material||Recommended thickness, mm|
|Stainless steel||up to 0.8|
|Brass and Copper||up to 1.5|
|Aluminum||up to 2|
|Stainless steel||up to 1.2|
|Steel||up to 1.5|
|Aluminum||up to 2|
|Plastic||up to 2|
|Stainless steel||up to 1.3|
|Steel||up to 1.8|
|Aluminum||up to 2|
Pay attention! In order to carry out effective metal cutting with the help of the “Scissors” nozzle, the power of the drill must be at least 2700 rpm. The recommended indicator for the “Cricket” nozzle is 1500-3000 rpm (depending on the material), and for the “Beaver” nozzle – at least 1500 rpm.
The main types of drill attachments for cutting wood
The nozzle, designed for cutting wood, has a rather complex structure. This mechanism resembles a jigsaw by its principle of operation. With the help of this device, you can cut wood whose thickness does not exceed 2 cm, as well as cut plywood sheets and chipboard.
In addition, the drill saw attachment can be used not only for wood, but also for cutting plastic and thin sheets of steel. For this reason, this device will be a very useful addition to a set of tools in a home workshop. It is worth noting that the cost of such a nozzle is very high, this is due to the complex structure of its mechanism.
On sale you can find whole sets that include:
- the nozzle itself (mechanism);
- three saber saws of different configurations;
- hex key for the cartridge.
Saber saws are made of durable plastic. Removable accessories in the kit vary in length and shape of the teeth. The scope of their application depends on the configuration of these products. There are such types of saws:
- for cutting wood;
- for quick wood cutting;
- for cutting metal (the saw has a small length and is set with small teeth).
Removable plastic files are light in weight, and therefore very convenient to use. The nozzles are fixed in the lock with a special screw.
Characteristics and application of angular drill nozzles
Several types of removable devices for performing various operations can be attributed to the category of angular drill attachments. Some tips are designed to create holes in places where a tool with a conventional drill will not reach. There are nozzles with adjustable and stationary angle. In the second case, the device is rotated 90° and fixed in this position.
Corner fixtures can also be used as limiters. In fact, this nozzle simultaneously performs two functions: it limits the depth of the hole being formed and provides the necessary position of the drill, as a result of which the angle is accurate.
In addition, you can find a screwdriver attachment for a drill on sale. It has a more complex structure than the usual version. Such devices allow you to tighten fasteners (screws) at different angles.
Important! The attachment for tightening fasteners can only be used with those models of the tool in which it is possible to reduce the speed of revolutions.
Angular type nozzles are usually sold as kits, which include tips of various diameters. Thanks to this, it is possible to install screws and self-tapping screws of different sizes. In rare cases, there are removable devices that allow you to turn an electric drill into a grinder with an angular design.
Other types of useful drill attachments
There are many other narrowly focused nozzles that cannot be classified into general categories due to their specificity, but many of them can be useful both in construction and in everyday life. For example, devices for sharpening drills will allow you to maintain this type of components in the proper form.
With the help of a pump nozzle on the drill, solutions and liquids can be pumped from one place to another. Such devices are used in combination with a very powerful drill. This type of nozzles will be useful in a private or country house in the event that an emergency situation arises.
Owners of suburban housing can benefit from removable drill nozzles. They are used for plucking wild or domestic poultry. At the same time, the skin and meat are not damaged.
All kinds of cutters will be a great addition to a home workshop. With their help, craftsmen can decorate products made of wood with relief patterns, as well as create grooves and holes, get rid of some defects.
This is not the end of the list of commercially available removable nozzles for electric drills. There are dozens of other devices that allow you to increase the functionality of this tool and add new features to it. Some of them can be made independently. In any case, it is necessary to adhere to safety precautions and check the reliability of fixing the nozzles.
