Frequently asked questions
What supply voltage should I use?
The motor is rated 3–12 V DC, and the listing mentions a 12 V 1 A supply. Lower voltage reduces speed and torque. Do not exceed 12 V.
Which drill bits can I use?
The collet accepts bits from 0.5 mm to 3.2 mm in the listed sizes. Choose a bit whose shank matches one of these sizes, and use it on soft materials such as plastic, wood and thin aluminum.
