Consider the stated short cordless runtime and the unresolved battery and accessory details against your intended tasks.

Frequently asked questions

What work is this rotary tool intended for?

The listing describes engraving, grinding, polishing and sanding, including smoothing PLA and ABS 3D-print layers and drilling small holes.

How long does the battery last?

The product information claims about 30 minutes of wireless use and a 60-minute charge from 0 to 100%. It also says the tool can be used wired, but does not specify the conditions for that use.

What accessories are included?

Features claim a 38-piece accessory kit, and the explicit contents list names one 38-piece kit. The accessories are not itemised in that list, so check the selected listing for the exact contents.

Which battery does it use?

The listing has conflicting battery information: its details name an LR44 battery and a lithium-ion cell. Confirm the supplied battery configuration with the retailer before purchase.
