ARROWMAX (sold on Amazon as AM ARROWMAX) makes small, cordless rotary tools shaped like thick pens. An arrowmax mini engraving pen spins a tiny bit at high speed so you can write names on tumblers, etch patterns into glass, carve wood, or polish metal, without the cord and bulk of a full-size rotary tool. Most of the kits come in a metal carry case with an OLED screen on the pen showing speed and battery, which makes them popular gifts for crafters.
The six ARROWMAX kits below include four engraving pens with 30 to 42 bits, one Bluetooth app-controlled pen, and one mini drill pen for jewelry and resin, and they differ mainly in speed range, number of accessories and how you control the speed.
ARROWMAX Engraving Pens Compared
| Kit | Speed range | Accessories | Runtime | Speed control |
|---|---|---|---|---|
| AM ARROWMAX Mini Engraving Pen (30 bits, black) | 15,000 to 30,000 RPM | 30 diamond bits | Up to 2 hours | 4 speeds, forward and reverse |
| AM ARROWMAX Electric Mini Engraving Pen (SGS, grey) | Up to 30,000 RPM | 42 | Up to 90 minutes | 4 RPM modes, forward and reverse |
| AM ARROWMAX Mini Engraving Pen (SGS, black) | Not listed | 42 | Up to 90 minutes | 4 RPM modes, forward and reverse |
| AM ARROWMAX Mini Engraving Pen (SGS MINI, Bluetooth) | 10,000 to 20,000 RPM | 36 | Up to 90 minutes | App, 1,000 RPM steps |
| AM ARROWMAX Mini Drill Pen (SDS) | Up to 900 RPM | 10 drill bits | Not listed | 4 or 5 speeds |
| AM ARROWMAX Smart Engraving Pen (SGS PRO) | Not listed | 42 (30 engraving, 12 polishing) | Not listed | 5 RPM modes plus Smart Motion |
A few terms, explained simply. “RPM” (revolutions per minute) is how fast the bit spins; higher speeds cut hard materials like glass and metal more cleanly, while lower speeds give more control on soft materials. “Bits” are the interchangeable tips: engraving bits (often diamond-coated) cut lines, and polishing bits smooth and shine. “Forward and reverse” lets the bit spin either way, which helps left-handed users and certain textures. A “hollow-cup motor” is a lightweight motor design ARROWMAX says gives more torque, meaning turning strength, in a small body.

AM ARROWMAX Mini Engraving Pen
Best for: Tech-minded crafters wanting app control
Pros
- Bluetooth app, 1,000 RPM steps
- 36 accessories
- Magnetic charging
- Up to 90 minutes runtime
Cons
- Top speed 20,000 RPM
- Case type listed two ways
Best for: Gift-givers wanting the 42-bit kit in black

- Up to 90 minutes runtime
- OLED display
- 1-year manufacturer warranty
Cons

- Light-duty only
Best for: Beginners wanting the widest speed range
Pros
- 4 speeds from 15k to 30k RPM
- Forward and reverse rotation
- 30 diamond bits
- Up to 2 hours runtime
Cons
- Fewer bits than 42-piece kits
- No polishing bits listed
The AM ARROWMAX Mini Engraving Pen in black is the newer kit with the widest listed speed range: a 4-speed motor from 15,000 to 30,000 RPM. The listing says this handles toughened glass and hardwood, and describes a high-torque design.
It comes with 30 CNC-machined diamond bits and claims compatibility with more than 50 surfaces, including metal, ceramic, stone and leather. One click switches rotation direction for left-handed users, and the squared-off handle stops it rolling off the table. An OLED display shows speed, battery and direction, and the 500mAh lithium polymer battery gives up to 2 hours of use, the longest runtime stated here. It arrives in a gift box.
This is the one we would suggest for a beginner who mostly wants to engrave. It gives way to the 42-bit kits if you also want polishing and sanding accessories.

AM ARROWMAX Electric Mini Engraving Pen
Best for: Crafters wanting engraving plus polishing
Pros
- 42 accessories with aluminum case
- Hollow-cup motor, 3x torque claim
- Magnetic in-box charging
- One-hand speed and direction
Cons
- Speed range listed inconsistently
- Light-duty only
The AM ARROWMAX Electric Mini Engraving Pen (SGS, grey) is the ARROWMAX mini engraving pen 42 bits kit, packed in an aluminum case. It uses a hollow-cup motor that the listing says has three times the torque of a standard motor, with a diamond tip for fine detail.
You change speed and direction with one hand: the power button toggles direction and a gear key cycles through four RPM modes. The 42 accessories cover grinding, polishing, shaping, sanding, wood carving and engraving, though the listing does not itemize them and says the tool is not for heavy-duty work. The 5V rechargeable battery runs up to 90 minutes, and a magnetic charger lets you charge the pen inside its box. The specifications give both minimum and maximum speed as 30,000 RPM, which conflicts with the four-mode description. It weighs 0.36 kg.
This suits crafters who want one kit for engraving, polishing and small carving jobs. If app control appeals, look at the Bluetooth SGS MINI.
AM ARROWMAX Mini Engraving Pen 42 Bits in Black
This AM ARROWMAX Mini Engraving Pen is the black version of the 42-bit SGS kit. Its feature bullets match the grey model: hollow-cup motor, one-hand speed and direction changes with four RPM modes, 42 light-duty accessories, an aluminum case, OLED display, and a 5V battery with up to 90 minutes of use plus magnetic in-box charging.
This listing adds a 1-year manufacturer warranty, which the grey listing does not mention. It does not list speed figures in its specifications. Dimensions match the grey version at 8.86 by 2.95 by 1.18 inches.
Choose between the two 42-bit kits by color preference and whether the stated warranty matters to you. For a gift, black often looks sleeker in the case.
AM ARROWMAX Mini Engraving Pen SGS MINI with Bluetooth App
This AM ARROWMAX Mini Engraving Pen (SGS MINI, grey) is the ARROWMAX Bluetooth engraving pen. With the optional Android or iOS app, you can set speed in 1,000 RPM steps from 10,000 to 20,000 RPM and choose direction, which gives finer control than preset modes.
It includes 36 accessories: 24 engraving bits and 12 polishing bits, plus a storage bag, manual and USB cable. The title mentions an aluminum case, while the components list says a storage bag, so check which you receive. The 5V battery runs up to 90 minutes, with magnetic in-box charging. Its top speed of 20,000 RPM is lower than the 30,000 RPM kits, which may matter on glass and hard metals.
This suits tech-minded crafters who like dialing in exact speeds for delicate work. For maximum speed on hard surfaces, the 30-bit or 42-bit pens are stronger.
AM ARROWMAX Mini Drill Pen for Jewelry and Resin
The AM ARROWMAX Mini Drill Pen (SDS) is not an engraver: it is the ARROWMAX mini drill pen for making small holes, spinning slowly (up to 900 RPM) for control rather than speed. That makes it ideal for resin charms, beads, jewelry, wood and plastic.
It includes 10 titanium-coated steel drill bits from 0.6mm to 2.2mm on a universal 2.35mm (3/32-inch) shank, stored in a magnetic CNC alloy box that holds up to 20 bits. It has LED lights, an OLED display, a 500mAh battery and USB-C charging. The title says 5 speeds while the specifications say 4, and the specification type “Drill Press” does not match this handheld tool.
This is a smart add-on for resin artists who already own an engraving pen. For engraving names or patterns, choose one of the SGS pens instead. If you are putting together a bigger gift for a craft room, a compact 3.2 cu ft mini fridge with freezer can keep resin supplies and drinks cool nearby.
AM ARROWMAX Smart Engraving Pen SGS PRO for Finer Control
Best for: Experienced crafters wanting finer control
Pros
- Smart Motion twist speed control
- 5 RPM modes
- 30 engraving plus 12 polishing bits
- Magnetic charger included
Cons
- Runtime not stated
- Heavier at 12.6 ounces
The AM ARROWMAX Smart Engraving Pen (SGS PRO) is the ARROWMAX smart engraving pen with a unique Smart Motion System: the pen adjusts its speed based on how you twist it, which the listing says keeps engraving and polishing consistent.
It offers 5 RPM modes with forward and reverse in each, a hollow-cup motor, a diamond-tipped head, and 42 accessories (30 engraving bits and 12 polishing bits) in an aluminum case. A 5V rechargeable battery and magnetic charger are included. One bullet calls it the “SGS MAX” rather than SGS PRO. The listing does not state runtime or speed figures, and it weighs 12.6 ounces.
This suits crafters who already engrave and want smoother control. First-timers may find the simpler four-mode pens easier to learn.
How to Choose the Right ARROWMAX Engraving Pen
- Engrave or drill: The SDS is a drill pen for holes. All others engrave.
- Speed: Up to 30,000 RPM helps on glass and metal; the Bluetooth SGS MINI tops out at 20,000 RPM.
- Accessories: 30 diamond bits for engraving only; 36 or 42 accessories add polishing.
- Control style: Button modes on most, app control on the SGS MINI, twist control on the SGS PRO.
- Runtime: Up to 2 hours on the 30-bit pen, 90 minutes on the SGS kits.
Gift idea for a hobby room: bundle an engraving pen with personalized tumblers to engrave and a small light-up mini fridge for the workbench.
