§ FAQ

What is the difference between the Dremel 3100 and the Dremel 100?

The 3100 adds variable speed control (5,000–35,000 RPM dial), 33% more amperage (1.2A vs 0.9A), and usually includes an attachment. The 100 runs at a fixed 35,000 RPM. For most users, the 3100 is the better buy unless budget is the primary concern.

What accessories fit the Dremel 3100?

The 3100 accepts all standard 1/8" shank Dremel accessories — the same vast accessory library that fits the 4000, 4300, 8240, and 8250. It uses a standard collet, so accessories with 1/32" or 3/64" shanks require a matching collet.

Does the Dremel 3100 have electronic feedback?

No. Electronic feedback (which maintains speed under load) is a feature of the higher-tier Dremel 4000 and 4300 series. The 3100 may slow down slightly under heavy cutting loads. For sustained heavy use, consider the 4000.

Can I use the Dremel 3100 for wood carving?

Yes, the 3100 is fully capable of wood carving. Variable speed lets you dial in the right RPM for your carving bits. However, for extended carving sessions, the 4000 or 4300 offer more consistent performance under load due to their electronic feedback systems.

How does the 3100-1/15 differ from the 3100-2/60?

They use the same 3100 motor and body. The 3100-1/15 includes 1 attachment and 15 accessories, while the 3100-2/60 includes 2 attachments and 60 accessories. Choose the 2/60 if you need a broader set of accessories out of the box.

Is the Dremel 3100 good for beginners?

Yes. The variable speed dial is intuitive, and the 15-accessory kit covers the most common tasks. It is a solid starter corded rotary tool for crafters, students, and light DIYers who want more flexibility than a single-speed tool.
