Nuances of application and selection of an impact drill

The modern versions of the ancient rotary hammer have gone through a lengthy process of development and transformed into a dependable and versatile electric tool. Aside from its original function of drilling holes in different materials, the impact drill can also be used as a mixer by adjusting its speed to the lowest setting. Additionally, it can be effectively utilized as a screwdriver. Furthermore, when the need arises, the tool can be swiftly converted into a grinder.

• pinion of the gear reducer;
• a pair of ratchets;
• rotating shaft;
• rolling bearing.

To ensure high-quality performance and greatly extend the lifespan of the product, it is recommended to lubricate the corrugated surfaces with a specialized grease, such as lithol.

In the image on the left, we can identify the following elements: 1 – ratchet, 2 – gear housing, 3 – spindle. Conversely, the image on the right displays: 1 – secondary ratchet and 2 – large gear reducer pinion.

Many individuals acquire this tool for personal use, specifically for domestic purposes. By utilizing a hammer drill equipped with an impact mechanism, one can effortlessly create perforations in concrete or masonry. Additionally, the drill can be utilized as a substitute for a robust mixer when undertaking repair tasks, such as blending wallpaper adhesive or preparing tile adhesive. The cordless impact drill has surged in popularity due to its wireless functionality, making it highly suitable for use as a screwdriver. Moreover, even when disconnected, the drill remains operational, provided that its battery is fully charged.

Varieties of tools

Electric drills are widely recognized as the tool of choice due to their versatile capabilities. They have the ability to fulfill various tasks and are classified into two primary categories:

• Household use
• Professional application

The first option is typically employed for temporary repair or occasional interior projects such as installing shelves and moldings, or outfitting the kitchen with wall-mounted cabinets. The second option is designed for frequent and prolonged use at construction sites on a daily basis.

Professional tools can have a maximum power of 1550 W, while drills used for household purposes typically have a power of up to 600 W. Lightweight drills with a power of up to 300 W do not have an additional second handle, unlike two-speed household impact drills. These lightweight drills are commonly used in difficult-to-reach areas where larger and more powerful tools cannot be used due to their size.

A cordless impact drill is a lightweight tool that provides a maximum torque of 24 N . m for soft metals and up to 55 N . m for hard metals. It is capable of drilling holes with a diameter of up to 13 mm. This portable tool falls into the category of two-speed impact drills.

All modern impact drills come with speed control, making them versatile tools that can drill holes at high speeds or drive screws at slower speeds. Many models also include a reverse function, which makes it easier to remove the drill bit from a hole or unscrew screws in screwdriver mode.

One question that often arises is the purpose of the long metal piece sticking out of the special holder on the removable handle. This is actually the drilling depth regulator. It allows you to accurately measure the depth of the drill hole and acts as a makeshift limiter during the drilling process.

Advantages of use

The advantages of any impact drill, compared to regular electric tools, are well-defined.

1. One advantage is the ability to drill holes in very strong materials. For this purpose, impact drills are equipped with special victorite tips, which allow for rotary and translational movements.
2. If the drill is equipped with a reverser and a speed regulator, it can also be used for unscrewing screws, self-tapping screws, and screws when dismantling various equipment.
3. Furthermore, with the use of special attachments, a drill can be transformed into a grinder or even a mini-bulldozer with slight modifications.

Technical nuances of the choice

When selecting an impact drill, it’s important to have a clear understanding of the specific tasks you’ll be using it for. A cordless impact drill is a valuable tool for working in a rural home or cottage, as it doesn’t require a power connection and can be used in outbuildings or on the garden plot where there may not be access to electricity. If you opt for a corded drill, it’s recommended to choose one with a cord length of at least 5 meters. This ensures that you can work without worry of the tool disconnecting from the power source due to excessive tension on the cord.

The reverse drill is a highly convenient tool that can be used as an alternative to a screwdriver. It is particularly useful when drilling into materials such as concrete or brick, as the reverse function helps to easily remove the drill from the hole during breaks in work, allowing the cutting tool to cool down. When choosing a reverse drill, it is important to consider the amount of torque it offers. The higher the torque, the easier it is for the electric motor to work, resulting in faster and higher-quality drilling.

Many reverse drill models also come with additional features:

• Speed control can be adjusted by pressing the start button, with stronger presses resulting in faster rotation.
• A processor is included in some models, allowing users to select the optimal rotation speed.
• The button can be fixed in a certain position to prevent hand fatigue during extended use.

All the details should be taken into account before purchasing a tool, rather than when it is already in use – this will enable the user to select the exact tool they need, without paying for unnecessary power.

It is important for every user to understand that for home use, an impact drill with a metal body should be chosen: this option will offer a longer lifespan compared to a similar tool made of plastic.

The greater the power, the quicker and more effortless it becomes to bore a hole with impeccable edges in any hard material, yet the tool’s weight and size increase. A 400 W impact drill weighs 1.4 kg, while a 1000 W drill nearly doubles in weight – this increase in mass is a result of the enlarged main gearbox dimensions. Certain manufacturers preserve the tool’s compactness by incorporating small, yet powerful electric motors with high torque reducers – however, this arrangement significantly raises the price.

What is the difference between household and professional tools

At times, it can be challenging to make the correct decision when faced with a multitude of options: there are various models available for home use as well as professional activities. Household impact drills are designed with aesthetic appeal and several enhancements that prioritize ergonomics.

Using such tools is effortless and enjoyable, although many homeowners prioritize technical specifications over visual appearance.

One key distinction between a drill intended for home use and one for technical purposes is how they operate. While a home drill is typically used on an occasional basis, a technical drill is designed to withstand constant and heavy use. As a result, technical drills are more powerful and larger in size. These models feature a modified design, with a gearbox enclosed in a durable steel housing and internal components engineered for superior cooling.

The electric motor is safeguarded from dust as the professional tool is suitable for use in any surroundings, be it draughty interiors of under-construction buildings or dusty basements where electrical wiring and other improvements need to be done.

The professional impact drill is a highly powerful and top-quality tool with exceptional reliability in all its parts, specifically designed for prolonged usage in the most unfavorable conditions.

In order to select an outstanding and dependable tool for home or professional activities, it is important to prioritize the principle – the finest impact drill boasts the highest technical indicators within its category. The crucial aspect is to meticulously inspect the impact drill prior to making payment and not compromise on quality, as you will be purchasing a tool for long-term use.
