Learning to correctly read the technical specifications of a tool

The descriptions of each model contain abbreviations and special symbols that are understandable to the master, but can confuse a person who is not previously familiar with the engraver. What should you pay attention to first when viewing descriptions?

The designation "Rotation speed, rpm" is the most important, it reflects the number of revolutions made by the shaft per minute. This value can vary from 15 to 35 thousand. When choosing a tool, you need to remember what task it should perform. If you are going to be working with high density material, you will need an engraver with a high RPM. A small amount is optimal for polishing various surfaces.
“Power, W” is the second thing you need to focus on. This indicator indicates the service life of the motor, which can vary from 35 to 300 W. For long and heavy construction work, you should choose a tool with high power; for making openwork jewelry, a low-power engraver is suitable.

When leafing through the catalog with the presented assortment, you should pay attention to the weight of each product. As a rule, it does not exceed 500 g, but there are models that weigh 1.5 and even 2 kg! When working with such an instrument, you will need to pause to rest your wrists and forearms. However, it has its advantages: this engraver is more powerful and can be equipped with a cooling system that prevents the shaft from overheating and contributes to a long service life of the working parts.

Buyer's Guide

The term "dremel" can cover a wide range of hand tools. Generally speaking, there are two categories of this tool.

Handheld tools are typically small, lightweight tools with small motors. They are suitable for jobs that require more control and fine detail, such as engraving, polishing, shape cutting and the like. Cutting Tools – These devices have larger motors and are better suited for cutting various building materials.

Why you might need a rotary saw

Dremels have a variety of uses and are used in a variety of home improvement projects. Different brands have their own unique features, but regardless of their differences, they are equally effective at cutting, polishing, sanding, shaping and finishing wood.

Cutting Engravers have special attachments that can be used for small cutting tasks such as wood, plastic, fiberglass and pipes.

Polishing They are ideal for polishing jewelry, silverware, coins and more.
Sanding For projects that require meticulous tasks, such as removing rough edges, rotary power tools are suitable. You can sand a piece of wood or remove rust from a metal area using the appropriate accessories.
Milling A router can cut grooves and holes into a piece of wood, plastic, rubber, and even metal.
Woodworking Woodworkers use Dremels to carve wood to create complex designs.
Engraving wood / glass / metal With the right accessories, you can use the engraver to create patterns on the surface of various materials.

Key Considerations

Rotary tools are designed to perform efficiently on any home improvement task. Whether you are a professional or a hobbyist, you need to learn some of its basic features to get the most out of this tool. Here are some key features worth paying attention to:

Applications Although rotary tools generally operate in the same way, there are differences in their applications. Heavy duty tools are designed for professional work because they are larger. They tend to be heavier and a little larger, but are well suited for demanding tasks. On the other hand, smaller tools are used for woodworking, small parts and crafts.
Wireless/Wired You can find both wired and wireless devices. Cordless tools are more convenient because the user does not need to plug them into a power source, but corded tools are usually lighter because they do not have a built-in battery. Therefore, when it comes to mobility and short-term use, cordless tools are preferred, but in terms of unlimited power consumption and continuous use, a corded tool has the advantage.
Speed Engravers have different speeds, and the wider the range of speeds, the more versatile the tool becomes. In this case, you should pay attention to the stability of revolutions throughout the entire speed range.
Equipment / Accessories The number and availability of accessories depends on the manufacturer. Some models are immediately equipped with a large set of accessories and can immediately perform a huge range of tasks, others have 3-5 attachments in the basic configuration and require additional investments to purchase accessories. An important aspect here is the interchangeability of devices between other brands.
Easy bit changes When performing complex jobs, you may need to change bits frequently. That's why; some models have multiple spindle locks. Consider the tasks you intend to perform and purchase a tool that allows you to easily change the accessories you require.
Ergonomics Check whether the tool has a comfortable shape. Vibration may occur during operation, so it is important to ensure a secure grip in various positions.
Replaceable brushes The ability to replace motor brushes when worn will extend the life of the tool without capital investment.

Which engraver is better to buy for your home?

The engraver's design resembles a drill. It consists of an electric motor, a drive and a holder for fixing the nozzle. Typically the holder is of the collet type and is suitable for cylindrical shanks with a diameter of 1 to 4 mm. Let us pay attention to the differences that may occur in different models.

What is the difference between impact and rotary type engravers?

First of all, engravers differ in their operating principle. There are two possible options here.

Impact engravers

Impact engravers resemble a hammer drill in their operation. They cut material through a series of high-frequency blows. Such machines have a narrow purpose only for engraving.

What features of engravers should you pay attention to when choosing?

The principle of operation of the engraver is very simple - the electric motor of the device drives a shaft with a cartridge and a working attachment, which processes the material.

When choosing equipment of this type, you need to pay attention to its main parameters and features:

Type of food. More powerful network models are recommended for intensive and long-term work. If convenience is more important, you should take a closer look at self-powered devices. It should be noted that battery models are less productive than networked counterparts.
Equipment and accessories. The number and type of engraver attachments vary greatly depending on the model and configuration of the latter. To perform basic tasks, you may need drills of different diameters, sanding drums, brushes, sanding and cutting discs. It is useful if the device is equipped with a flexible shaft for working in hard-to-reach places and a desktop mounting system.
Quick change of attachments. Some modern engravers support a keyless tool change option. The operation is performed literally in one motion, which is very convenient and significantly saves the user’s time.
Soft start system. Models equipped with this function provide more precise operations without unexpected jerks when turned on. The system limits the starting current, due to which the electric motor gains speed gradually.
Speed regulation and stabilization. An extremely useful option that allows you to select the required rotation speed of the chuck depending on the task being performed. The system records the value set by the user and maintains it at a constant level throughout the entire process.
Start button lock. A common mechanism in many power tools allows you to lock the start button when it is on. This is convenient when performing large volumes of work and lengthy operations.
