A mini-drill, like most power tools, can be powered either by mains or battery. Before deciding which option is right for you, consider the conditions in which you intend to use this device. If you have constant access to the power grid, feel free to choose the first option. If you plan to work with a mini-drill outdoors or in rooms where there are no outlets, give preference to a cordless tool.
One of the most important parameters of the engraver is the rotation speed. Its size is various devices can vary between 15-35 thousand revolutions per minute. Mini-drills with minimum rotation speeds are intended primarily for polishing and grinding. If you need the device for sharpening and cutting, choose a model with the maximum number of revolutions.
On modern market Among power tools, you can find simple engravers with a constant rotation speed, which reduce the voltage of the motor during operation, and therefore are not intended to perform demanding tasks. high precision operations, and variable speed mini drills that allow you to change the number of revolutions per minute as needed.
Avoid buying an engraver that is too small and light, no matter how convenient you may find it. The fact is that compact instruments do not have a cooling system, so they overheat very quickly. While using this mini drill, you will have to stop working every few minutes.
The most popular and reliable manufacturers of mini-drills are: Zubr, Kalibr, Energomash, Sturm, Dremel, Ryobi.
Mini drill attachments
Models that include a flexible shaft and a hanging bracket are not only more convenient to use. Also, these elements provide faster and better cooling of the tool engine.
Before you buy a mini drill, make sure that the kit includes attachments designed to perform various functions. For grinding, sharpening saws and leveling surfaces, they are made of various densities nozzles in the form abrasive wheels and stones. For carving and milling materials such as stone, wood and metal, attachments in the form of sharp or, conversely, rounded cones and wire brushes are suitable. For cleaning and polishing, it is better to use disc attachments and bristle brushes with varying amounts of bristles.
A large drill does not always solve the problem. The heavy body with an electric motor does not make it possible to perform high-precision operations manually, because the master’s hands get tired quickly. Hard-to-reach places are also impossible to drill due to lack of access, and flexible drives, often included with power tools. Therefore, you need to buy a mini drill. These are devices of a particularly compact size that allow you to operate manually with drilling and engraving operations on metals, plastic, ceramics or wood. They differ from larger analogues internal device, cartridge design and performance characteristics.
Key Features
The mini drill collet clamp is the only type of locking device. The impact type is not provided, so working on stone is impossible. It is only possible to perform precise engraving. Uses a small asynchronous electric motor with big amount revolutions, and the body is made of durable corrugated material that is easy to grip by hand. At the moment, there are two types of design: with an autonomous motor and a flexible drive. By analogy with dental instrument the latter option is often called a drill, and the drill itself looks like a thick stationery pen.
What to look for when choosing
Be sure to consider the following characteristics when choosing the optimal model:
- Regulator mini drills can allow smooth speed changes or step switching. It all depends on the task at hand. Typically, stepless change is necessary when working with a large number of different materials, for example in repair shops.
- Number of revolutions directly affects the ability to drill into delicate materials. You will be able to choose between rotation speed and torque, which are the basic characteristics. Over time, you will be able to adapt to your power tool and drill the most accurate holes. Typically values start from 10,000 to 50,000.
- Weight. This is also a determining factor. At long work your hands get tired quickly.
- Case length. It is necessary to understand for what operation the device will be used. Don't forget to add the length of the clamped drill.
- Shank. Depending on the type of cartridge, it may be different design this part.
- Supply voltage. It will not be possible to use the electrical network directly due to the windings being too weak. An adapter is required, the output voltage from which ranges from 6 to 36 volts.
- Chuck material. The soft brass used allows, in case of jamming of the drill, to use turning in the chuck without damaging the electric motor. There are no other types of protection in such a compact package.
Industrial options
Due to the high energy consumption with a large number of connection points, these devices can be connected to a pneumatic or hydraulic drive. They are characterized by increased torque and simplicity of the device. Their cost is so low that they are considered a consumable material. There is practically nothing to break in them. They are especially often used in mechanical engineering to create military equipment and all types aircraft. You can also buy a micro drill of this type for household needs, but then you will need to purchase a compressor or hydraulic unit. This is a profitable purchase for repair shops.
Engraving is one of the oldest methods of decoration. People carved designs to decorate their homes and tools, and the work of skilled craftsmen was always in value. Today this craft can become available to everyone thanks to electric engraver or mini drills. Engravers can be used to apply patterns to various materials, make jewelry, modeling and all kinds minor works: drilling, cleaning, polishing. These tools have a wide range of applications due to the large number of attachments. 
Device
The engraver resembles a drill or grinder, consists of a housing with a motor and a movable shaft with a mount for a working attachment. Please note that the collet (chuck for clamping equipment) may have different diameter and is only suitable for bits with a specific shank size. The most common size is 3.2 mm, but collets for engravers with a diameter of 1 to 4 mm are also available. The chuck can be quick-release or screw-type, requiring a key for fastening. The key one is more reliable, can withstand heavy loads, and the quick-clamping one reduces the time for changing attachments.
Exist impact and rotary type engravers, they differ in the mechanism of operation. Impact hammers function like a mini hammer drill and are only suitable for engraving, while rotary hammers are a more versatile tool, allowing you to grind, drill and cut. Engravers are also distinguished by type of power supply; there are mains and battery-powered ones. Like other tools, corded models provide greater power and battery-powered mobility. More expensive engraver models are equipped with a shaft rotation speed controller. It can be electronic with fine tuning or simple mechanical, limiting the motor voltage. Impacts allow you to adjust the depth of travel of the nozzle. 
Characteristics
- Shaft rotation speed. This is the main characteristic of the engraver. It is higher than other power tools and can be from 15 to 35 thousand revolutions per minute. To work with soft materials(wood, plastic, copper) and polishing will not require high speeds, and for dense products made of stone or steel, you should use a tool with at least 30 thousand revolutions per minute. For impact engravers, the corresponding characteristic is the number of strokes per minute, which can reach 6000.
- Engine power. Another important parameter, which directly affects the performance of the tool. Measured in watts (W), there are devices from 35 to 300 W. Please note that the price depends on the power, so if you do not plan to use it professionally, then it is quite possible to purchase a low-power entry-level engraver. For long-term work, especially with hard materials, you should take an engraver with a power of 200-300 W.
Engraver attachments
Nozzles (cutters) are sold individually or in sets, from small ones of five to six pieces, to universal kits, which include one hundred or more items. The equipment differs in shape (cylindrical, disk, spherical, conical), purpose and material from which it is made. There are a huge variety of attachments for various purposes; they can be roughly divided into two groups:- Carving and grinding. For cutting, milling and grinding hard metal and stone, nozzles coated with technical diamonds or aluminum oxide are usually used; for soft products made of wood, glass and ceramics, silicon carbide abrasive is used.
- Polishing and cleaning. For polishing, you can use vulcanite nozzles or rubber ones with an abrasive coating. Felt and felt attachments are used with a special polishing paste, which consists of paraffin and sanding powder of different grain sizes. Various brushes are used for cleaning; for example, a metal brush can remove rust, paint, or create scuffs for an antique effect.
Choice
It is worth deciding in advance what materials you will be working with, why and how often you will use the tool, this will greatly facilitate the choice of model. You shouldn't be limited by what's included; most likely you'll use a limited number of attachments. Therefore it is better to take good tool with the basic set. Consumables you will still have to purchase it sooner or later, especially if you are constantly using it for some specific tasks. When choosing, pay attention to the ergonomics, dimensions and weight of the device. Working with an uncomfortable engraver will make you tired faster. The weight of such devices can be from 500 grams to 2.5 kilograms. In addition, important indicators, especially during long-term operation, are noise level and heat generation. Low-power devices do not heat up or make much noise, and professional engravers usually equip them with a cooler. Some devices come with a flexible shaft, a device similar to an extension for rotary engravers, which increases maneuverability and significantly improves convenience. The tip of the flexible shaft is thinner than the tool, which is better for fine and precise work. When using it, the engraver should be mounted, for example, on a special stand. For work you should choose a powerful one professional tool from manufacturers such as Dremel, Proxxon, Foredom, and for hobbies a household model from the brands Bort, Einhell, Hammer, Skil, Sturm and others is suitable. Follow safety precautions and do not neglect protective equipment. Fine dust and chips fly around during operation, so be sure to wear goggles and a mask.
