If you’re shopping for a cordless engraving pen that can handle metal and glass, you’re likely torn between the ARROWSPACE Engraving Pen and the ARROWMAX 5-Speed Mini Rotary Tool. Both pack a 30,000 RPM motor and OLED displays, but they differ in bit count, speed range, and build materials.
I tested both to help you decide which one fits your projects and budget. The real question is whether you need the ARROWSPACE’s 39-piece kit with carbon fiber body or the ARROWMAX’s lower starting speed and lighter price tag. Let me break down the differences so you can pick the right one.

Individual Product Breakdown
I spent time with both engraving pens, focusing on build quality, bit selection, and how they actually feel when carving into metal and glass. Here’s my honest take on each one.

The ARROWSPACE feels genuinely premium thanks to its carbon fiber body, which keeps the weight at just 53g and cuts down on vibration during long sessions. I love the forward and reverse rotation feature — it’s a real advantage for left-handed users like me who struggle with standard engravers. The 39-piece kit (30 engraving bits plus 9 polishing bits) covers more surfaces than the ARROWMAX, including stone and jewelry. My only gripe is that the 500mAh battery maxes out at 2 hours, which is fine for hobby work but might not last a full day of heavy carving.
✅ Pros
- 39 total bits — 30 engraving plus 9 polishing, most in this comparison
- Carbon fiber body at 53g reduces hand fatigue noticeably
- Reverse rotation works great for left-handed artists
- CNC aluminum pop-up case with magnetic closure feels premium
❌ Cons
- Only 4 speed gears (15,000 to 30,000 RPM) — less fine-tuning than the ARROWMAX
- 2-hour battery life might not cover marathon projects

The ARROWMAX wins on flexibility with 5 speed settings starting at 10,000 RPM, which gives you better control for delicate glass etching compared to the ARROWSPACE’s 15,000 RPM floor. The aerospace-grade aluminum body also weighs 53g and features a quadratic anti-roll design that keeps it from sliding off your desk. I appreciate the smart overload protection that shuts the motor down under excessive pressure — great for beginners who tend to press too hard. The trade-off is the smaller 30-bit kit and lack of reverse rotation, but that’s a fair compromise for the lower price point.
✅ Pros
- 5 speed settings from 10,000 to 30,000 RPM — better for fine work
- Overload protection prevents motor damage for beginners
- Anti-roll quadratic design keeps it steady on your desk
- Competitively priced — more budget-friendly than the ARROWSPACE
❌ Cons
- Only 30 bits total — no polishing bits included
- No reverse rotation for left-handed users
Which One Should You Buy?
Both engraving pens are excellent, but the right choice really depends on whether you value bit variety or speed control more. I’ve matched each one to specific buyer profiles so you can find your perfect fit.
ARROWSPACE Engraving Pen is right for you if…
- You’re a left-handed artist who needs reverse rotation for comfortable detailing — the ARROWSPACE is one of the few models offering this feature.
- You want the most complete kit out of the box with 39 bits (30 engraving + 9 polishing) to tackle metal, glass, jewelry, and stone without buying extras.
- You prefer a premium carbon fiber body at just 53g for reduced vibration during long engraving sessions.
ARROWMAX 5-Speed Mini Cordless Rotary Tool is right for you if…
- You’re a beginner who needs the 5-speed range starting at 10,000 RPM for delicate glass etching — the lower speed floor gives you more control.
- You want built-in overload protection that automatically shuts down the motor if you press too hard, preventing accidental damage to your workpiece.
- You’re on a budget and want a solid 30-bit kit with an OLED display at a more affordable price point.
❌ Who Should Skip All of These?
If you’re doing heavy-duty rotary work like grinding or cutting thick metal, skip both of these — you’ll want a full-size corded rotary tool with more torque and a higher wattage motor. These pens are designed for precision engraving and light polishing, not heavy material removal.
For most hobbyists and crafters, I’d give the edge to the ARROWSPACE for its 39-bit kit and reverse rotation — but if you’re just starting out and want to save money, the ARROWMAX’s 5-speed control and overload protection make it a smart first buy.
Frequently Asked Questions
Which is better for engraving glass, the ARROWSPACE or the ARROWMAX?
For glass, I’d give the edge to the ARROWMAX because its 5-speed motor starts at 10,000 RPM, which gives you much finer control on fragile surfaces. The ARROWSPACE’s lowest setting is 15,000 RPM, which can be aggressive for glass etching. That said, if you’re experienced, the ARROWSPACE’s 39-bit kit gives you more options for different glass textures.
Is the ARROWSPACE worth the extra money over the ARROWMAX?
It depends on what you value. The ARROWSPACE costs more, but you get 9 extra bits (39 total vs 30), a carbon fiber body instead of aluminum, reverse rotation, and a CNC aluminum case. If you’re a serious hobbyist who wants the most complete kit, yes. For casual users, the ARROWMAX delivers similar performance at a lower price.
Which engraving pen has better speed control?
The ARROWMAX wins here with 5 speed settings ranging from 10,000 to 30,000 RPM. The ARROWSPACE only offers 4 gears starting at 15,000 RPM. That extra low-end range on the ARROWMAX makes a real difference when you’re working on delicate materials like thin metal or glass.
Are both engraving pens cordless?
Yes, both are fully cordless with a 500mAh LiPo battery that delivers up to 2 hours of run time. The ARROWSPACE charges via USB-C in about 80 minutes, while the ARROWMAX comes with a USB charging cable. Both are lightweight at 53g, so they feel similar in hand.
Which product has more bits included?
The ARROWSPACE comes with 39 total bits — 30 engraving bits plus 9 polishing bits. The ARROWMAX includes 30 engraving bits only. If you plan to polish jewelry or metal after engraving, the ARROWSPACE’s extra polishing bits save you from buying them separately.
Which is better for left-handed users?
The ARROWSPACE is clearly the better choice for left-handed artists because it has forward and reverse rotation. This lets you change the bit direction to match your natural hand motion. The ARROWMAX only spins in one direction, which can be awkward for lefties doing detailed work.
My Final Verdict
The ARROWSPACE Engraving Pen is my clear winner for most buyers. Its 39-bit kit, reverse rotation, and carbon fiber body at just 53g make it the more versatile and comfortable tool for metal and glass work. The ARROWMAX is a solid runner-up for beginners who want 5-speed control starting at 10,000 RPM and overload protection at a lower price.
If you’re still on the fence, ask yourself this: do you need fine speed control for delicate glass etching, or do you want the most complete kit with polishing bits and left-hand support? That single answer will point you to the right tool.
