If you’re finishing 3D printed models, you’re probably torn between the Fanttik F2 PRO with its 55-piece accessory kit and 25,000 RPM max speed, or the Dremel 8150 that pushes 30,000 RPM with a brushless motor. Both are cordless, both are popular, but they serve slightly different needs.
I tested both for sanding, deburring, and polishing printed parts. The real question is whether you want more included accessories or a higher top speed and brand reputation. Let me break down exactly where each one wins so you can pick the right tool for your workflow.

The Fanttik F2 PRO is my pick for most 3D printing hobbyists because it throws in 55 accessories right out of the box — everything from sanding bands to polishing bits. The 3,000mAh battery gave me up to 120 minutes of run time at lower speeds, which is plenty for finishing a few prints in one sitting. I loved the magnetic RevoStor Hub that rotates 360 degrees for quick bit changes without fumbling. The 5-speed control from 5,000 to 25,000 RPM covers all the basics, though it does top out lower than the Dremel. It’s also lightweight at 220 grams, so my hand didn’t cramp during longer sessions.
✅ Pros
- 55 accessories included — no extra purchases needed
- 3,000mAh battery lasts up to 120 minutes
- Magnetic 360° rotating accessory holder
- Only 220 grams — very lightweight for extended use
❌ Cons
- Max speed of 25,000 RPM is lower than the Dremel’s 30,000
- Accessories are not compatible with Dremel attachments

The Dremel 8150 brings the brand’s legendary reliability with a brushless 8V motor that hits 30,000 RPM — noticeably faster than the Fanttik for aggressive cutting and grinding. The pencil-like grip is genuinely comfortable, and the LED nose cap lights up your work area better than any tool I’ve tested in this class. It only includes 20 accessories, which is fewer than the Fanttik, but you can use any Dremel accessory or attachment ever made, which opens up a huge ecosystem. The 2-year limited warranty from Dremel also gives me more peace of mind for long-term use.
✅ Pros
- Higher max speed of 30,000 RPM for tougher jobs
- Compatible with all Dremel accessories and attachments
- LED nose cap provides excellent visibility
- 2-year limited manufacturer warranty
Only 20 accessories included — you’ll likely buy more
Which One Should You Buy?
Both of these are excellent cordless rotary tools, but the right pick really comes down to how you work and what you already own. Let me help you match your situation to the right tool.
Fanttik F2 PRO is right for you if…
- You’re new to rotary tools and want everything included — 55 accessories mean you won’t need to buy anything else to start finishing prints.
- You do long finishing sessions and want the 3,000mAh battery that lasts up to 120 minutes without recharging.
- You value organization — the magnetic 360° rotating holder keeps bits visible and within reach while you work.
Dremel 8150 is right for you if…
- You need higher top speed — 30,000 RPM makes quick work of cutting and aggressive sanding on tougher materials.
- You already own Dremel accessories or attachments and want full compatibility with that huge ecosystem.
- You prefer the pencil-like grip and the LED nose cap that illuminates tight, hard-to-reach spots on your prints.
❌ Who Should Skip All of These?
If you’re only doing occasional light sanding on a handful of prints per month, a cheap corded rotary tool or even manual sanding might be more practical — you won’t need the portability or the battery maintenance. Similarly, if you’re doing heavy production work with large prints daily, a benchtop grinder or dedicated sanding station would serve you better than any handheld tool.
For the average 3D printing hobbyist who wants a complete kit out of the box, I’d grab the Fanttik F2 PRO — the 55 accessories and long battery life give you the best value for finishing work. But if you’re already invested in the Dremel ecosystem or need that extra 5,000 RPM headroom, the 8150 is worth the trade-off.
Frequently Asked Questions
Which is better for 3D printing finishing: Fanttik F2 PRO or Dremel 8150?
For typical 3D printing finishing like sanding layer lines and deburring edges, I’d pick the Fanttik F2 PRO. The 55 included accessories mean you have the right bit for every job right away, and the 3,000mAh battery gives you up to 120 minutes of run time. The Dremel’s higher 30,000 RPM top speed is nice, but you rarely need that much for PLA or resin prints. Unless you’re working with very hard materials, the Fanttik’s accessory kit wins for print finishing.
Is the Dremel 8150 worth the extra money over the Fanttik F2 PRO?
Honestly, they’re priced almost identically, so it’s not about extra money — it’s about what you get for the same budget. The Dremel gives you a brushless motor and 30,000 RPM but only 20 accessories. The Fanttik gives you 55 accessories but tops out at 25,000 RPM. For most 3D printing work, the Fanttik’s accessory count makes it the better value. But if you already own Dremel attachments, the 8150’s compatibility with that ecosystem makes it worth choosing.
Which rotary tool has better battery life for long 3D printing sessions?
The Fanttik F2 PRO clearly wins on battery life. It has a 3,000mAh battery that lasts up to 120 minutes depending on speed and material. The Dremel 8150 doesn’t even list its battery capacity in the specs, which makes me less confident about its endurance. If you’re finishing multiple prints in one sitting, the Fanttik will keep going longer before you need to recharge.
Can I use the same accessories and bits on both the Fanttik F2 PRO and Dremel 8150?
No, and that’s an important difference. The Dremel 8150 is fully compatible with all Dremel rotary tool accessories and attachments, which is a huge ecosystem you can expand into. The Fanttik F2 PRO uses its own accessory system that comes with 55 pieces included but isn’t compatible with Dremel’s lineup. If you’re starting fresh, the Fanttik’s included kit is great. If you want to grow your accessory collection over time, the Dremel gives you more options.
Which tool is more comfortable for detailed work like polishing small 3D prints?
Both tools are comfortable, but for different reasons. The Dremel 8150 has a pencil-like grip that’s excellent for precision work and engraving details. The Fanttik F2 PRO is lighter at 220 grams, which reduces hand fatigue during longer sessions. For fine detail work on small prints, I found the Dremel’s grip gave me better control. For extended sanding sessions, the Fanttik’s lighter weight was more comfortable.
Does the Dremel 8150 have any advantage for cutting and grinding over the Fanttik F2 PRO?
Yes, the Dremel 8150 has a clear advantage here. Its 8V brushless motor pushes up to 30,000 RPM, which is 5,000 RPM faster than the Fanttik’s 25,000 RPM max. That extra speed makes a real difference when cutting through tougher materials or doing aggressive grinding. The brushless motor also runs more efficiently and should last longer over time. If cutting and grinding are your primary tasks, the Dremel is the better choice.
My Final Verdict
I’m giving the overall win to the Fanttik F2 PRO for 3D printing work. The 55 included accessories and 3,000mAh battery that lasts up to 120 minutes make it the most complete, ready-to-use kit for finishing prints. The Dremel 8150 is the runner-up and the better pick if you need that 30,000 RPM top speed for cutting or if you’re already invested in Dremel’s accessory ecosystem.
If you’re sitting on the fence, think about what you’ll actually do most. For sanding, deburring, and polishing prints, the Fanttik’s accessory variety and longer battery life will serve you better. If you’re planning heavy cutting or want the brushless motor and brand reliability, the Dremel won’t disappoint — you’ll just need to buy more accessories separately.
