Afantti EUCMB101 cordless mini rotary tool, three speeds review
A small cordless rotary tool on a 380 mAh battery with three speeds up to 15,000 rpm and copper collets, which its maker restricts, in capitals, to small and light projects.
The bottom line An inexpensive cordless tool that is honest about its limits: three speeds, a small battery and a clear warning against heavy work. Collet sizes and runtime are missing.
The Afantti EUCMB101 listing, bullet by bullet
Five bullets: cordless use on a 380 mAh battery; three speeds of 5,000, 10,000 and 15,000 rpm; a small, light body with copper collets and a durable motor; a capitalised restriction to small and light projects; and uses from grinding and polishing to engraving, cutting, drilling and rust removal.
A small tool that says so
“ONLY for small and light projects.” The fourth bullet sets the limit itself. A 15,000 rpm ceiling and a small battery are consistent with it, and the page takes the maker at their word.
Speeds as no-load figures
5,000 to 15,000 rpm is how fast the tool spins free. Under load it slows, and the listing gives no torque or power figure to say by how much.
What the Afantti listing omits
Collet sizes, accessory contents, runtime and charging time. For a cordless tool the last two decide how long a session lasts.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 16 € to 18 €.
It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.
The American Amazon store returned no entry, so the buy button there opens a search rather than a missing page.
