    Отличная миниатюрная дрель. Рекомендую. Можно использовать как ручную дрель или в составе самодельного станка. Трехкулачковый патрон надежно фиксирует сверла разных диаметров. В отличие от цанг патрон не нужно менять при смене диаметра сверла. Отсутствие фиксирующих винтов на конусе Морзе обеспечивает минимальную вибрацию. Алюминиевый кронштейн в виде уголка не мешает держать дрель в руках и позволяет быстро закрепить дрель на направляющей станка. При напряжении питания 12 В ток холостого хода 0,3 А. Дрель легко сверлит сверлом диаметром 1,5 мм алюминиевую пластину толщиной 1 мм. Ток при этом может увеличиться до 0,8 А. Чтобы одеть втулку с конусом Морзе на вал двигателя я рекомендую втулку предварительно аккуратно и равномерно разогреть газовой горелкой. Чтобы установить кронштейн на двигатель потребовалось аккуратно снять краску с внутренней стороны отверстия для шейки двигателя и заменить винты из набора на винты с потайной головкой. Excellent miniature drill. I recommend. It can be used as a hand drill or in a home-made machine. Three-jaw chuck fixes the drill of different diameters. In contrast to the collet chuck should not be changed by changing the diameter of the drill. The absence of the fixing screws on the cone Morse ensures minimal vibration. Aluminum bracket in a corner does not interfere to keep the drill in his hands and allows you to quickly fix the drill guide on the machine. When the supply voltage 12 V no-load current of 0.3 A. Drill easy drill holes of 1.5 mm diameter aluminum plate of 1 mm thickness. The current may be increased up to 0.8 A. To wear sleeve with Morse taper on the motor shaft sleeve, I recommend at first carefully and evenly heat the sleeve by a gas burner. To install the bracket on the engine required carefully remove the paint from the inner side of the hole for the neck of the engine and replace the screws from the kit on the screws with countersunk head.

    1. The chuck runs true, a bit grit in it, but otherwise very nice. 2. The motor isn't a ball-bearing one, sleeve bearing only. The parameters are also quite different. Idle speed at 24V is about 12000, idle at 12V about 6000. Motor parameters (measured from the received motor): kN = 514.4 rpm/V - Speed constant kV = 1/kN = 1.944 mV/rpm - Voltage constant (motor voltage = kV*N+Ra*I = kV*N + Ra * (tq/kT + i0 + i0*N) ) kT = 18.57 mNm/A - Torque constant i0 = 115mA - idle current at zero speed (theoretical) i1 = 10.74µA/rpm - idle current speed factor idle current = i0 + i1*N[rpm] Ra = 2.1Ω - armature resistance At 5A it should deliver about 0.1Nm of torque Idle current is about 180mA at 12V and about 240mA at 24V, drops somewhat once the motor is warm.

    I have made a drill press of it

    These motors are great for making workshop tools for the miniature hobbyist. I bought 2 sets and have made a drill press with one and am going to make a mini lathe with the other. Good prices and good stuff; you cannot go wrong at Bang-good!

    Ürün açıklamalardaki gibi, gayet güzel. Kısa sürede kargoladılar ama ülkeye geç geldi. Tavsiye ederim. Just like as described, no problem. I do recommend. Thanks for the fast shipping, as well.

    This is a very useful device for the home lab. I use this device to drill holes in PCB with a hand

    The board works perfectly and finely adjusts

    I received mine last week and assembled it immediately. Hammering the 'JT' bush onto the motor shaft was a bit scarey but worked well. I connected it to a battery via a PWM speed controller, excellent; so good I ordered another one today. I tested for run-out (wobble) and I found a distortion of 0.002" or less at 1 & 1/4" out from the nose of the chuck with a 1/8" shaft installed. Dam good, Banggood.

    From this you can create several sets of tools for cutting, sanding, grinding, polishing, drilling. It is a very useful tool for a good price. I applaud them for its simply and variability of use. I recomending to this assembly DC speed controller (for example: http://www.banggood.com/PWM-DC-Motor-Speed-Switch-Controller-Control-Reversible-Regulator-p-912617.html?rmmds=search). I can only recommend. Banggood congratulation.
