Frequently asked questions
Can I drill PCBs with this mini drill?
Yes, the 0.5–3.0 mm chuck accepts small PCB drill bits. Use suitable bits, secure the board firmly and wear eye protection.
Is it safe to run from the 220 V mains?
Power it only through the supplied adapter, which converts 220 V AC to 12 V DC. Keep the adapter dry, do not leave the tool running unattended, and disconnect power before changing bits.
