Why do you need an impact drill?

What is the difference between an impact drill and an impactless drill and peorator

For any construction and repair work, electric hand tools, such as rotary drills, regular drills, and impact drills, are used. At first glance, this tool is similar in appearance, but differs in functionality. It is necessary to know what is the difference between an impact drill and a hammerless drill, what is the difference between these power tools and how to choose the right one.

This drill is designed for drilling holes in metal, wood, plastic and durable materials. brick and concrete. From an electric motor, the rotation is transmitted through a gear box to a cam-type chuck in which the cutting tool (drill bit) is fixed. For working with hard materials, bricks and concrete, one rotation is not enough to make a hole.

It differs from an ordinary drill by the presence of a ratchet mechanism, which gives the tool a reciprocating motion. a blow, they allow you to drill holes in a solid material.

Important! Ordinary drills are not suitable for such work, you must use a tool with a pobeditovye tip.

The impact mode in this power tool can be switched on and off. At idle speed the percussion mechanism does not work, it starts only by pressing the tool.

The construction market today offers a wide range of electric drills. Impact drill, angle drill, mixer drill, geared drill It is not difficult to get confused in such a variety. However, the impact drill, which is the main object of this article, differs favorably from the listed samples. Than? Let’s get to the bottom of it.

An impact drill is a multi-purpose device. the main difference is the special mechanism of movement of the drill bit that performs not only rotary but also reciprocating movements. This advantage of the impact drill mechanism allows you to work with all kinds of materials: wood, metal, plastic, brick, concrete.

But this is not the only advantage. The best impact drills are high-powered devices used for:

  • threading in the metal;
  • screwing in and out screws;
  • drilling in wood, metal, natural stone;
  • for making holes in concrete and bricks.

Special purpose drills

Drill. a tool multifunctional in principle, but for the comfortable performance of specific tasks, some models are distinguished by a special design, a set of peculiar characteristics. Let’s take a closer look at them.

Impact drill

Drill with a hammer can help drill into lightweight concrete or masonry, to work on soft materials, the function is disabled. Let’s say right away that this is not a peorator: the impact power here is ten times less (joules are not even indicated in the manual) and the principle of operation of the beating mechanism is different. In an impact drill, the main work is done by the ratchet, which consists of their gear clutches that separate under load (one of them slips off the other) and the shaft moves steadily.

In the peorator, the impact is obtained from the work of a special “drunken” bearing and pneumatic elements. The drilling function is the main function of the rotary drill, but the impact mode is only an auxiliary function of the drill. First, it can drill only light concrete and brick; second, such mechanism serves for a very short time; third, other parameters of the tool (weight increases, spindle backlash is present, accuracy of impactless drilling decreases).

Drill impact force and its resource directly depend on the tool pressure force, on the strength and geometric characteristics of the gear, on the location of the ratchet (the further from the chuck. the weaker is drilling).

So, an impact drill is a good solution for rare “10 minutes a year” drilling jobs, an amateur version. These machines can in no way replace the drill, and the well-known versatility comes at the price of lowering some of the standard features. There are no rules without exceptions, percussion drills can be found in professional lines (Bosch GSB 16 RE, Makita HP2071).

Screwdriver for screws

Work with fasteners is one of the most important functions of the drill, in the chuck of any of them you can clamp a bit and twist screws, but some machines are adapted for this better than others:

  • Reverse is very important because screws occasionally need to be unscrewed during work, fortunately, this feature is available in almost all modern drills.
  • Variable speed. It is not possible to work with self-tapping screws at high speed. it is necessary to slow down. There are preset options, a sensitive button is used, multi-position gearbox (multiple speeds).
  • Impulse mode (short jolts). Good for removing consumables.
  • Removable chuck sometimes allows the bit shank to be inserted directly in the spindle (Kress 650 BS). Smaller and lighter machines.
  • Adjustment of tightening torque. Such a function is considered very specific, it is characteristic of the tool, which is allocated to a special class (screwdriver). Read more about cordless electric screwdrivers in the article “How to choose a cordless screwdriver”.

Perhaps it is worth mentioning drills-electric screwdrivers with automatic cassette feed screws, a very handy device for large-scale fixing work (for example, Makita 6844).

Mixer drill

Many drills (if not to speak about “pure” mixers with a chuck under the whisk) capacity from 1000 watts are capable of mixing viscous solutions. For this kind of work, they are often equipped with extended auxiliary and D-shaped main handles (Makita 6300-4). In addition, power drills have a multi-speed gearbox, allowing reduction of the gear with an increase in torque (Bosch GRW 11 E). High power of such machines and availability of several protection systems allow installing large tooling: drills of large diameters, drill bits (including diamond drilling). Many such drills have a break clutch that protects the worker and the machine from damage if they jam (Makita DBM080).

Angle drill

Usually it is a lightweight compact machine, designed to work in hard-to-reach places. They are equipped with an angular gearbox, so the spindle and accessories are positioned to the body axis at right angles (as in an angle grinder), such as the Makita DA3011F. Otherwise. special differences angular drill does not have, well, except that their power is generally low and percussive function can not be. The real alternative to a highly specialized angular drill are angular attachments for standard models, which allow you to solve special problems.

Screwdriver type

Such a tool is used mainly for screwing and unscrewing screws. It has a telling name. an electric screwdriver. Such a device is usually inherent in such characteristics as:

  • switchable speed mode, i.e. low and high speeds;
  • the possibility of setting a certain force at which the gear unit will disengage, so that the entire mechanism does not fail.

An electric screwdriver can be wired or cordless, or rather cordless. And it is the second type that is most widely used because of the convenience of its use. Most models have two batteries included. This makes it possible to work on one battery while charging the second one.

Pros and cons

The main advantage of impact drills is that you can work with almost any material, even the hardest. The main disadvantage includes a reduced accuracy of drilling, if compared to a household tool. In addition, impact drills create a lot of noise in operation.

Other advantages, about which it is worth knowing:

  • Wide range of drilling capabilities in hard materials.
  • It is possible to install different types of drills.
  • Easy to repair.
  • Very long tool life.
  • To work with hard materials, you have to exert great physical force.
  • If you actively use the machine when working with concrete, it will have a shorter service life.
  • If you compare the impact drill to a rotary hammer drill, the former has a weaker impact.

Important! Almost all professional devices are equipped with a function for adjusting the speed of rotation of the shaft.

What else to consider when choosing a drill

When choosing a device, in addition to the basic characteristics, it is necessary to take into account additional features. These should include:

  • Locking the power button. This characteristic allows you to work safely with the device;
  • Automatic shutoff feature. The presence of this function prevents the drill from burning out with prolonged use. The device automatically shuts off in the event of heat;
  • backlight. Allows you to make a hole accurately, even in a dark room;
  • Dust collector. Facilitates further cleaning of the room.

The additional criteria should also include the availability of nozzles. Not superfluous will be the second handle, with which to work in hard-to-reach places will be convenient.

Service life and reliability

In the peorator internal elements are protected from severe loads and vibrations by pneumatic mechanisms. The product also includes a special coupling to avoid malfunctions if the drill bit runs into a reinforcement mesh in the concrete or gets stuck during operation.

The impact drill will last long if used strictly for its intended purpose in softer materials. When used in concrete on the ratchets of the tool is a serious load, so the parts fail quickly enough.

Attention! Severe vibration has a negative effect on the operation of all components and mechanisms, and they fail in a short period of time.

To the delight of neighbors

Not everyone has held a peorator in his hands, but the sound of this tool behind the wall is familiar to all. Why the neighbors choose it for repairs?

Peorator is preferable when you are going to drill a hole in the wall or chisel the floor, and if you drill holes, then the deep, large diameter and in large quantities. The tool can penetrate hard materials up to and including natural stone. So there is a suspicion that 50% of neighbors in the past life were miners.

Just as in the case of drills, we will consider the mains-powered tool.

Criteria for choosing a good tool

The choice in favor of one or another model depends on how you plan to use it. If you need to drill a couple of holes from time to time and occasionally screw in screws, you will be enough and an impact drill. And if you move into a new apartment, or are going to do major repairs in the present apartment, which involves drilling out walls, cutting jambs, chiselling of floors, you should definitely buy a peorator.

What to look for

If you have opted for an impact drill, here are a few points to consider when buying the tool:

  • Power. The larger it is, the lighter and more convenient the product is to work with.
  • Number of revolutions (rotation speed) at idle speed.
  • Variable speed adjustment.
  • The diameter of the holes the impact drill produces in different materials in impact mode.
  • Availability of reversible motion (movement in both directions). For use when you need to remove a screw or when you need to remove a jammed drill bit from material.
  • Number of speeds (one, two or more).
  • Availability of additional “screwdriver” attachments.

Impact drill can also be used as a grinder, angle grinder and stationary drilling machine (fixed to the table).
