One of the very first rotaries found dates back to the second century BC. It was a bronze pointed peak, curved in the upper part in the form of a crank for the hand, for which the sharp tip was rotated. On the middle part there are stops for a wooden sleeve. The upper part ended with a handle and an emphasis. Such a hand-held mechanical drill was a similar to the well-known brace in our time.

Is the bobbin a product of the past?

Although the whirlpool has its origins in ancient times, it has not lost its purpose even in our time. The development of technical progress has not bypassed this seemingly simple product. equipped modern devices it is fundamentally different from that found in the second century BC, the main differences are:

this is the presence of a cartridge, which, depending on the design, can clamp a shank with a diameter of 0.8 mm to 13 mm .;
the second is a ratchet, which is designed to help make holes in materials with limited space, for example, near a wall. With its help, you can make not a circular, but a translational movement of the handle using a ratchet. The device of the ratchet mechanism is simple - clinging to the notches of the wheel connected by the rod to the working body, it transfers the force applied to the handle only in one direction;
also, the height of the shank and the purpose of the actuator can be changed at the rotator, depending on the need.
When changing the working tool, the brace can be used as a screwdriver or just a drill.

Drill application

Drills are widely used in construction and garden work. Hand and electric drills make a hole in the ground much faster than when digging.
Winter fishing does not do without holes. They are quickly and accurately made in a layer of thick ice when ice fishing with the same device is much more accurate and faster than ice picking.

The design of rotaries and drills for all purposes of their varieties was not only in the tips of the cutting device, but also in the withdrawal of waste material from the work area - along the screw or screw grooves on the working body.

Ratchet Rotator 250mm Stanley 1-02-715

A versatile tool designed to work with high force and a large universal tool. The brace is equipped with a four-jaw self-centering chuck for the diameter of the round shank of the working tool up to 13 mm.

Due to the presence of a ratchet mechanism, it is possible to work with any nozzles in hard-to-reach places. The handle and thrust head are made of thermoset high-strength plastic and are close to metal in strength.

The landing of the handle and thrust head is made on ball bearings, which reduces the resistance to torsion to zero and virtually eliminates their failure.

Chrome-plated parts give the product a beautiful aesthetic appearance and protect against corrosion.

The tool can be used not only for drilling holes in wood and other materials, but thanks to direct muscle control, to quickly cut threads with taps and dies. Another brace is used to work with fasteners; with it, you can easily twist and unscrew screws and screws.

The production of handicrafts of the American company Stanley has been founded since the beginning of the century and has a high reputation all over the world. A universal mechanical hand drill can be bought at specialized dealer centers of the company, stores. Numerous Internet resources also offer this and many other tools with instant clearance and delivery by mail to the specified address.

Manual mini drills mechanical

Such devices are so miniature that it is more common to call them a pencil or a pen than a drill, but by design they are just drills.
Average size of fixtures: Length 12-18 cm. Weight 20-25 gr. Can be used with conical and conventional drills, like screwdrivers or an awl. Shank diameter clamp from 0.2 to 3.2 mm.

The body is made of a hollow rod, into which a freely rotating stop - head is inserted from above. This emphasis is usually made removable. Drills or working bits with a flat and cross sting can be placed inside the cavity of the rod.

The lower part of the body is made with a threaded groove, onto which the cartridge is screwed. Regular collet chuck with clamping external thread for clamping.
The most demanded manual mini drills are mechanical in professions related to electronics and electrical engineering, with such an improvised tool it is very convenient to clean or make new holes in the circuit boards of electrical devices, disassemble small mechanisms, and use it as a marker for making notches on hard surfaces.

The body is usually made of duralumin with external square notches in the middle part for greater grip with the fingers of the hand.

Multi Handle (Hand Micro Collet Drill from Wave)

It's no exaggeration to say that this is one of the most stylish and beautiful micro drills on the market. In addition, it is made very high quality and has the following advantages:

The case is made with large notches of durable aluminum alloy.
The material is a thin-walled tube, the inner cavity is closed with a plug with an annular rubber seal. The rubber ring does not interfere with the slippage of the cover during rotation. But when removed from the case, it has significant resistance.

The clamping device is made according to the type of clamping 3 jaw chucks for drills. All other similar models are purely collet clamps.
The product is produced by the Japanese corporation Wave.

Collets

The principle of operation of the collet clamp can be understood from the figure. The body of the clamp is made of high quality spring steel. The classic round body has slots into which the working tool is inserted with its edges.

If the tool shank is round, then it is clamped by unscrewing the expanding rod in the center or outside the body with a clamping sleeve.

The Wave 3-jaw chuck holds and centers the work drill shank more securely than a collet. This is especially true for shanks with small diameters from 0.3 to 1 mm. Carbide-tipped jaws are spring-loaded for ease of use when changing tools. The clamp is made by simply twisting the skirt of the cartridge case.

By purchasing a beautiful and high-quality instrument, as a bonus, you can enjoy working with a good instrument.

How much progress has been made

If there is no desire to twist by hand, then you can purchase the Micro 8050-35 product from the American company Dremel

This machine is powered by a built-in li - ion battery with a voltage of 7.2V and can serve not only as a tool for drilling holes, but, depending on the interchangeable nozzle used, as a grinder or a grinder. The weight of the device is only 250 g.
Primary packaging in cardboard box on which bright pictures show the available nozzles, methods of work and a photo of the tool itself.
Includes 18 nozzles Charger with power supply for output voltage 12V, 150-200 mA. The block is universal, but it is better to check it once again by looking at the inscription as in the picture. If there is no such inscription, then you can purchase a suitable adapter, many of them are inexpensive for sale. Judging by the feedback from readers, the charger also works well from 220 V. Of course, before plugging in 220V (instead of 115V), it is better to consult a specialist or a seller. The package includes a box with accessories and a case for carrying the grower, as well as a standard number of nozzles 18 pieces, which include: polishing paste; metal mesh different hardness; conical cutters, cutting wheels, drills.
There is a backlight of the working area, which turns on when the start button is pressed, the backlight is bright - four LEDs located around the spindle shaft.
The three-stage speed controller operates from the "plus - minus" button and has five adjustment steps in thousand rpm: 10; 15; 20; 25; 28. When turned on, the motor is set to medium speed. At the top of the case is a battery charge indicator, consisting of two LEDs: red light indicates the end of charging.

It should be remembered about the features of Li - ion batteries - regardless of the intensity of work, they must be changed every 5-6 years from the date of issue.

The domestic model is represented by "Whirlwind G-160GV"

Model with full electric drive and is a versatile tool for use from grinding to engraving.
The kit includes the grower itself, a plastic case, a flexible shaft, a set of nozzles.
The device weighs 630 grams with a rated power of 160 watts.
The speed of rotation of the nozzle is from 8000 to 30000 rpm and is regulated by a switch located on the back of the case. The number of adjustment steps is from one to seven. On the opposite side is the power button.
The motor is commutator, modernized with quick access to the electric brushes, which allows them to be quickly changed without opening the case.
The versatile interchangeable bit system includes 2 x 3.2mm collets and 1 x 2.3mm collet.

Unforgettable! about safety: before changing the working nozzles, it is necessary to disconnect the device from the mains.

A flexible shaft is used to work with small details and engraving. Installation of the shaft will not cause difficulties; for this, the end of the cable is inserted into the hole in the output shaft of the machine and fixed with a threaded clamp of the protective cover.

A metal bracket is provided on the back of the case for the possibility of hanging the tool.
A mini electric or mechanical drill can be bought at numerous dealerships and stores. On numerous Internet resources, you can place an order with delivery to the address; in case of poor-quality delivery, the supplier guarantees a refund. When buying a manual mechanical drill in Moscow by Internet order or a phone call, the goods are delivered to your home address with payment for the goods to the courier.

Single speed mechanical hand drill

One of the stages of improvement rotary steel hand drills mechanical
This device has a gear, which allows you to increase the number of revolutions of the working shaft several times. The amount of revolution depends on the number of teeth of the large wheel with teeth applied to it, which is engaged with the gear fixed on the working shaft and through it with the cartridge. The value of revolutions or, as it is also called speed, depends on the gear ratio of this gear pair - the greater the ratio of the number of teeth, the less effort and greater speed. The handle for the drive is fixed on the big wheel. The drill chuck usually has an internal thread and is screwed to the shaft with it. Handles for gripping brushes can be on ball bearings, bushings, or simply rigidly fixed to the base, made of wood, various plastics, textolite. Rotaries and handheld devices for drilling holes are easy to use, because the design is collapsible, which is very convenient for carrying in small cases or bags.

Devices with a two-stage gearbox

In addition to a single-stage gearbox, two-speed gearboxes are installed on manual devices. The manual mechanical two-speed drill is a compact, lightweight, reliable, multifunctional device. This design reduces the size gear wheels, dimensions, weight, and also in some models an additional gear is used, which, when engaged, is already a two-stage small-sized multiplier (gearbox working to increase the angular velocity of the output shaft), which significantly expands functionality devices, for example, at a low drill speed, you can drill fragile materials like tiles, at high speed - metal.
The main advantage of two-speed products: independence from electricity; output power depends only on muscle strength; high reliability, small dimensions and weight. Also, the advantages include: for a drill, a manual mechanical price is much lower than a mains power tool and even lower than those working from autonomous power sources.
