Speed range and collet size decide which accessories are worth buying · review
A pen-shaped cordless engraver weighing 0.10 kg with five speeds, a 3/32-inch collet, 20 engraving bits, an LED work light and a 700 mAh battery the listing rates for over two hours.
The bottom line A precise, quiet engraving pen with a stated collet, battery life and useful indicators. Its speeds carry no rpm, and the charging cable has to come from elsewhere.
Six bullets: a smooth, quiet motor at 32 dB with a concentric shaft for cleaner lines; 20 engraving bits and five speeds for wood, metal, glass and plastic; battery, charging, speed and overload indicators and an LED work light; a 700 mAh battery for over 2 hours, USB-C charging in about an hour, cable not included; a 0.10 kg pen-shaped body and a hard case with magnetic slots that charges the pen; and a collet for 3/32-inch accessories.
A pen weighing 0.10 kg. It is held like a pencil for lines and shading, not like a hand grinder for cutting. The listing is built around that use, and the five other rotary tools here are not.
3/32 inch, 2.3 mm. Many rotary tool bits use a larger 1/8-inch shank, so accessories from general kits will not all fit. The sixth bullet states the size so a buyer can check.
Five levels are described as moving between delicate detail and deeper engraving. No rpm is given for any of them.
At the last look-up, the German Amazon store was asking roughly 60 €.
It is sold in the American Amazon store as well, in its own currency, which the euro figures above leave out on purpose.
The British, French, Italian and Spanish Amazon catalogues list the product, yet no seller was offering it.
