World’s smallest Power Drill 3D printed in New Zealand

By -

A maintenance engineer from Auckland, New Zealand named Lance Abernethy has made a very small power drill using his Ultimaker 2 3D printer in just 25 minutes!


It is unofficially the world’s smallest working power drill with 17 x 7.5 x 13 mm size and a 0.5-mm bit.

It is fit for making holes through soft objects like human skin (see below).


The maker first made a 3D model with Onshape 3D software with his power drill as a reference and used a hearing aid battery in his machine along with some wires from a headphone cable and a tiny motor.

Check out the drill in use below:

The maker plans to make a power drill that is even smaller than this one in future!
