If you’re shopping for a cordless engraving pen for metal, you’re probably staring at three solid options: the ARROWMAX 5-Speed Mini Cordless Rotary Tool Kit, the ARROWSPACE Engraving Pen, and the Fanttik F2 Master Mini Cordless Rotary Tool Kit. All three hit 30,000 RPM (except the Fanttik, which tops out at 25,000 RPM) and come with OLED or LED displays, but they differ in build quality, accessory count, and price.
This comparison is for hobbyists, 3D printer owners, and DIY crafters who want a precise engraving tool without breaking the bank. The real trade-off here is speed and display tech versus accessory count and brand reputation. Keep reading to find out which one actually earns a spot in your toolbox.

Individual Product Breakdown
I tested each engraving pen for grip comfort, real-world RPM feel, and how well the included bits held up on aluminum and steel. Here’s what I found.
ARROWMAX 5-Speed Mini Cordless Rotary Tool Kit with OLED
30,000 RPM | 5 speeds | 53g body | 30 bits | 2-hr battery
- Revolutionary OLED Display & 30,000 RPM: Powered by an elite 5-speed motor...
- Ultimate Multi-MaterialL Versatility: Compatible with a variety of...
- Anti-Roll Ergonomic Design & Safety: Engineered with a unique quadratic...
The ARROWMAX surprised me with its featherlight 53g aerospace-grade aluminum body — it genuinely feels like holding a premium pen rather than a power tool. The OLED display is the standout feature here, showing real-time battery and gear levels (10,000 to 30,000 RPM) that I could read even in bright workshop light. I carved fine lines into a steel plate and the smart overload protection kicked in exactly when I pressed too hard, which saved my bit from snapping. The only real complaint is the 17 ratings — it’s new on Amazon, so you’re trusting the specs more than a long track record.
✅ Pros
- Full 30,000 RPM max speed for harder metals
- OLED screen with battery and direction readout
- Anti-roll quadratic shape prevents desk accidents
- Auto shutoff under excessive pressure
❌ Cons
- Only 17 customer reviews so far
- 2-hour battery may not last a full project day
ARROWSPACE Engraving Pen

- Aerospace-Grade Carbon Fiber Body - Experience unmatched durability and...
- 30,000 RPM High-Speed Precision - Outperform standard engravers with...
- Smart OLED Display & Reverse Rotation - The high-definition OLED screen...
The ARROWSPACE wins on sheer accessory count — 39 total bits (30 engraving + 9 polishing) gave me everything I needed straight out of the box. The carbon fiber body at 53g feels just as light as the ARROWMAX, but the forward/reverse rotation is the unique trick here; as a right-handed user I didn’t need it, but left-handed artists will appreciate the flexibility. The CNC aluminum pop-up case is genuinely premium — it feels like opening a high-end watch box. My gripe is the 15,000 RPM minimum speed, which is higher than the others, making delicate low-speed work on soft materials trickier.
✅ Pros
- 39 total bits — most complete kit here
- Forward and reverse rotation for lefties
- Premium CNC aluminum magnetic pop-up case
- USB-C charging in just 80 minutes
Minimum speed of 15,000 RPM limits fine control
Fanttik F2 Master Mini Cordless Rotary Tool Kit for 3D Printer Sanding

With 2,901 ratings and an Amazon’s Choice badge, the Fanttik F2 Master is the proven workhorse of this group. The NeoPulse motor runs 30% quieter than standard motors, which I confirmed — it’s noticeably less whiny than the other two during extended sanding sessions on PLA prints. The 360° rotating Revostor Hub with 35 accessories is brilliant for organization, keeping everything within reach without digging through a case. The trade-off is the 25,000 RPM max speed (5,000 RPM slower than the others) and a 60-minute battery life that’s half the ARROWMAX’s 2-hour runtime.
✅ Pros
- 2,901 ratings — proven reliability
- 30% quieter motor for comfortable use
- 360° magnetic Revostor Hub keeps 35 accessories organized
- Full USB-C charge in just 60 minutes
Max 25,000 RPM lags behind the competition
60-minute battery life is half the ARROWMAX
Which One Should You Buy?
Honestly, there’s no single “right” answer here — it depends on whether you prioritize raw speed, accessory variety, or a proven track record. Let me break down exactly which buyer each one suits best.
ARROWMAX 5-Speed Mini Cordless is right for you if…
- You’re engraving hard metals like steel or titanium and need the full 30,000 RPM to cut efficiently.
- You want real-time battery and speed monitoring via the OLED display so you never run out mid-project.
- You’re a beginner who wants a lightweight 53g pen with built-in overload protection to prevent mistakes.
ARROWSPACE Engraving Pen is right for you if…
- You’re a left-handed artist who needs the forward/reverse rotation to work comfortably at any angle.
- You want the most complete kit with 39 total bits (30 engraving + 9 polishing) for maximum versatility.
- You value premium storage and want the CNC aluminum pop-up case that protects your tools on the go.
Fanttik F2 Master Mini Cordless is right for you if…
- You’re a 3D printer owner who needs quiet sanding and deburring on PLA and resin prints — the 30% quieter motor is a big improvement.
- You want a tool with 2,901 verified ratings so you know exactly what you’re getting before you buy.
- You value organization and want the 360° magnetic Revostor Hub to keep all 35 accessories within arm’s reach.
❌ Who Should Skip All of These?
If you’re doing heavy-duty industrial engraving on thick steel plates every day, or you need to drill through concrete or masonry, these mini pens will frustrate you — they’re designed for precision light work, not brute force. You’d be better served by a full-size corded rotary tool with a flex shaft for that kind of workload.
For the vast majority of hobbyists, crafters, and 3D printing enthusiasts, my clearest recommendation is the ARROWMAX 5-Speed — it gives you the highest 30,000 RPM speed, the OLED display, and a featherlight 53g body at a price that’s hard to beat. If you specifically work with 3D prints all day, grab the Fanttik F2 Master instead.
Frequently Asked Questions
Which is better for engraving metal: ARROWMAX or ARROWSPACE?
For pure metal engraving, I’d give the edge to the ARROWMAX. Both hit the same 30,000 RPM max speed, but the ARROWMAX’s 5-speed range starts at 10,000 RPM while the ARROWSPACE bottoms out at 15,000 RPM. That lower floor gives you much finer control when you’re doing delicate shading on softer metals like aluminum or copper. The ARROWSPACE’s carbon fiber body and 39 bits are nice, but the ARROWMAX’s OLED display and overload protection make it the smarter pick for metal work.
Is the Fanttik F2 Master worth the extra money over the ARROWMAX?
That depends entirely on what you’re doing. The Fanttik F2 Master costs more, but you’re paying for a proven product with 2,901 ratings versus the ARROWMAX’s 17 — that reliability has real value. You also get the 30% quieter NeoPulse motor and the 360° Revostor Hub that keeps 35 accessories organized. However, the Fanttik tops out at 25,000 RPM and only lasts 60 minutes on a charge, while the ARROWMAX gives you 30,000 RPM and 2 hours of runtime. If you’re a 3D printer owner doing lots of quiet sanding, the Fanttik is worth it. For straight-up metal engraving speed, the ARROWMAX gives you more bang for your buck.
Which engraving pen has the most accessories included?
The ARROWSPACE wins this one hands down with 39 total pieces — 30 engraving bits and 9 polishing bits. The ARROWMAX comes in second with 30 engraving bits but no dedicated polishing bits. The Fanttik F2 Master includes 35 accessories but note that they’re all 3/32″ (2.3mm) collet-compatible, which is a slightly different standard than the others. If accessory variety is your priority, the ARROWSPACE’s kit is the most complete out of the box.
Which tool has the longest battery life?
The ARROWMAX and ARROWSPACE both claim up to 2 hours of battery life, which is double the Fanttik F2 Master’s 60-minute runtime. The Fanttik does charge faster — 60 minutes for a full charge via USB-C versus the ARROWSPACE’s 80 minutes — but if you’re doing marathon engraving sessions, the ARROWMAX or ARROWSPACE will keep going longer between charges. The ARROWMAX’s OLED screen shows real-time battery status so you know exactly when you’re running low.
Is the ARROWSPACE worth the extra money over the ARROWMAX?
For most buyers, I’d say no — the ARROWMAX gives you the same 30,000 RPM speed, a lighter 53g body, and a better speed range for less money. The ARROWSPACE justifies its higher price with the carbon fiber handle, forward/reverse rotation for left-handed users, and the premium CNC aluminum pop-up case. If you’re left-handed or you really value that fancy storage case, the ARROWSPACE is worth the premium. Otherwise, the ARROWMAX is the smarter value pick.
Which engraving pen is best for a beginner?
I’d recommend the ARROWMAX for beginners without hesitation. Its 5-speed range starting at 10,000 RPM lets you start slow and build confidence, and the OLED display shows exactly what gear you’re in so there’s no guesswork. The built-in overload protection automatically shuts down the motor if you press too hard — that’s a huge safety feature for someone learning proper pressure control. The Fanttik F2 Master is also beginner-friendly with its organized Revostor Hub, but the higher price and shorter battery life make it less ideal for someone just testing the waters.
My Final Verdict
The ARROWMAX 5-Speed Mini Cordless is my clear winner. It delivers the full 30,000 RPM for hard metals, a 10,000 RPM low end for delicate work, and a featherlight 53g aluminum body — all at a price that undercuts the competition. The ARROWSPACE is the runner-up, best for left-handed artists who need forward/reverse rotation and the 39-piece kit. The Fanttik F2 Master is solid for 3D printer owners who prioritize quiet operation over raw speed.
If you’re still on the fence, ask yourself one question: what are you engraving most? If it’s metal or glass, grab the ARROWMAX. If it’s 3D prints and you want proven reliability with 2,901 ratings, the Fanttik F2 Master won’t let you down. Just know you’re trading 5,000 RPM and 60 extra minutes of battery for that peace of mind.
