Should I buy a corded or cordless Dremel?

Across the reviewers we read, the split is clear: corded models like the 4300 and 4000 deliver constant power for long bench sessions, while cordless 12V models (8240, 8250) trade some runtime for portability. r/Tools commenters repeatedly note cordless models are 'more than enough' for hobby work, while heavy-duty users still prefer corded for sustained material removal.
