## What reviewers say

The only whitelisted tester with hands-on prose for this exact model is Pro Tool Reviews, which names the Dremel 8240 its best cordless rotary tool. It praises cordless versatility, the included flex-shaft attachment, and a 35,000 RPM top speed, while flagging a sparse accessory kit. No measured benchmarks were published for this model, and no other whitelisted outlet had coverage. (Based on 1 review, 2024-03-26.)

Praised: Cordless 12V design takes grinding, polishing, and cutting anywhere; Included flexible-shaft attachment handles a range of angles and positions; 35,000 RPM top speed is strong for a cordless model.
Flagged: Accessory kit is relatively limited.
Disagreement: Single-source only, so no cross-source comparison is possible. Pro Tool Reviews reported no physically measured benchmarks for the 8240 (its 12V, 2.0Ah and 35,000/5,000 RPM figures are manufacturer specs), so runtime and power claims remain unverified by any whitelisted tester.
