Top 5 Positive Customer Reviews for モーターは
The motor is fast enough for drilling PCB from 12V but I use it with 19V laptop adapter for the faster speed. The drill chuck feels cheap on the first touch because of the light weigh, but the grip is very good on it. The chuck trunk is made of Cu, jaws are metal, housing is eloxed aluminium. Drill bits are standard low quality, you need to sharpen them after 20-30 holes. I suggest to buy a kit of carbide drill bits for the longer lifetime. Highly recommanded for PCB drilling.
