Updated: 4 days ago
The Pocket NC V2 does something genuinely rare: it puts true 5-axis CNC machining on a desk. Not a rotary attachment bolted onto a 3-axis frame. Full simultaneous motion across five axes, the same fundamental capability used in industrial machining centers, in a machine that connects via USB and fits next to a monitor. Five-axis systems at this level of functionality are difficult to find in a desktop format at anywhere near this price.
The original Pocket NC raised $355,833 from 280 backers on Kickstarter in 2015, before a production unit existed. Penta Machine has spent a decade since delivering and refining that machine. The V2 now ships in two configurations: the V2-10 at $7,499 with a 10,000 RPM spindle, and the V2-50 starting at $10,799 with a 50,000 RPM NSK spindle. Both cut up to G5 titanium, accept standard G-code, and ship with Kinetic Control. Current lead time is 6 weeks.
What it does: True simultaneous 5-axis CNC machining in a desktop footprint.
What changes: Complex aluminum or titanium parts that require multiple setups on a 3-axis machine get completed in one.
What to know: Requires CAD/CAM workflow knowledge. The V2-50 also requires compressed air.
Track record: $355,833 raised on Kickstarter in 2015. Shipping and refined for a decade since.
From $7,499, ships in 6 weeks from Penta Machine
Quick Verdict
Who Is It For?
The Pocket NC V2 is for engineers, product developers, jewelers, and technically capable makers who cut metal prototypes regularly and have working knowledge of CAD/CAM software. The core buyer is anyone currently outsourcing aluminum, delrin, or steel parts to a machine shop for short runs and absorbing the lead time and cost of each design iteration.
Main Strengths
True simultaneous 5-axis motion at desktop scale: complex geometry in a single setup, no refixturing, no cumulative positional error between operations.
Cuts up to G5 titanium; tested on 6061 aluminum, 303 stainless, acetal, and wax. The V2-10 handles the material range most prototyping work requires without additional infrastructure.
Embedded simulator at sim.pocketnc.com included on both models: validate G-code before cutting stock, at no added cost.
±0.0005 in homing repeatability and Tool Center Point Control standard on both models, precision that holds for production prototype work.
1-year machine warranty and 2 years of remote service included, with a 6-week lead time from a manufacturer with a decade of delivery history.
Main Limitations
CAM software is not included and carries a real cost. Five-axis simultaneous toolpath capability is not free, and Fusion 360 now runs on subscription pricing. Budget for it before ordering.
The V2-50 requires a compressed air supply of 1 gallon per minute at 25 psi. Mandatory, not optional. The spindle warranty (3 months) is void without it.
The comfortable work envelope is approximately 3 inches cubed. Part size is a hard constraint regardless of budget or skill level.
Is the Pocket NC V2 Worth Buying?
If you prototype regularly in aluminum, delrin, brass, or steel and currently send those parts out, the V2-10 at $7,499 is worth calculating against your outsourcing spend. Five-axis capability means multi-setup jobs get done in one, and Penta's decade of delivery history substantially reduces the uncertainty that comes with hardware this specialized. If you have no CAD/CAM experience yet, build that first. Available at Penta Machine.
What Is the Pocket NC V2?
The Pocket NC V2 is a fully assembled 5-axis CNC milling machine that fits on a workbench. It cuts metal from solid stock using subtractive machining, with simultaneous motion across five axes: X, Y, and Z for linear movement, A for part tilt (-25° to 135°), and B for continuous rotation. Complex geometry, undercuts, and multi-face parts are completed in a single setup without repositioning.
Two spindle configurations cover different needs. The V2-10 runs at up to 10,000 RPM on an ER-11 collet system, requires no air supply, and handles the material range most small-shop and prototyping applications demand. The V2-50 reaches 50,000 RPM via an NSK high-speed spindle, requires compressed air, and delivers tighter surface finish tolerances. Both share the same 6061 aluminum frame, the same axis travel, and the same Kinetic Control platform.
Pocket NC was founded by a husband and wife engineering team who spent four years and five hardware iterations developing the original machine before the 2015 Kickstarter. Four years of iteration before asking for a single dollar is a detail worth noting. The project now operates as Penta Machine, with Tool Center Point Control standard on both models, rotary compensation built in, and tooling and vise hardware in the box on day one.
What Can the Pocket NC V2 5-Axis CNC Machine Actually Do?
Metal prototype iteration is where the V2 earns its place. A part sent to a machine shop comes back in days or weeks, and each design revision restarts that clock. On the V2, the same part is cut in hours, revised in CAD, and recut the same day. For any workflow that depends on physical testing rather than simulation alone, that compression matters.
The five-axis capability adds a specific advantage over 3-axis desktop machines. A bracket with features on multiple faces, a housing with angled ports, a small mechanical component with compound curves: these parts require multiple setups on a 3-axis machine, each demanding fixturing, re-zeroing, and careful alignment. Each step adds time and compounds positional error. The V2 handles them in a single setup, with the A and B axes doing the repositioning automatically.
The machine has found genuine use in jewelry and watchmaking, where small intricate brass or precious metal parts require tight tolerances at very small scale. University engineering programs use it for student prototype work. Robotics developers use it for small aluminum structural parts. The 3-inch cubed work envelope aligns well with all of these. It does not align well with larger workpieces, and that boundary is real.
The 5-axis capability is only worth paying for if your parts actually need it. Flat or prismatic parts with features on one or two parallel faces are handled fine by a 3-axis machine at lower cost and with a simpler CAM workflow. The V2 is the right choice when geometry demands it, not because five axes sounds more capable than three.
Pocket NC V2 Key Features and Specs: 5-Axis Motion, Spindle Configurations, Precision, and Materials
Pocket NC 5-Axis Motion: What Simultaneous Machining Delivers
Three-axis CNC machines move in X, Y, and Z. The Pocket NC V2 adds A and B: A tilts the part, B rotates it continuously. The cutting tool reaches the workpiece from nearly any direction without stopping the job to reposition. Each repositioning step on a 3-axis machine compounds error and adds setup time. The V2 removes those steps for complex geometry.
Both 3+2 machining (rotary axes index to a new surface, lock, then linear axes cut) and full simultaneous 5-axis motion are supported. Curved surfaces, undercuts, compound angles, and multi-face parts are handled in a single setup.
Pocket NC V2-10 vs V2-50: Spindle, Collet, and Air Requirements
The frame, axis travel, repeatability, and control software are identical on both V2 models. The decision is entirely about the spindle.
The V2-10 runs 2,000 to 10,000 RPM with an ER-11 collet (up to 1/4 inch shank), spindle runout of 0.0005 in or less, no air required. Collets are inexpensive and available from 1/8 inch to 1/4 inch and in metric equivalents. For aluminum, delrin, softer steels, brass, wax, and wood, the V2-10 covers the material range without additional infrastructure. It is the right starting point for most buyers.
The V2-50 runs 1,000 to 50,000 RPM via an NSK spindle, runout of 0.0001 in or less, and requires 1 gallon per minute of compressed air at 25 psi. Without air, chips can enter the spindle bearing and cause permanent damage. Penta will not honor the spindle warranty without confirmed air use. The spindle warranty is 3 months rather than the standard 1 year, consistent with industry practice for high-speed spindles. Choose the V2-50 if surface finish tolerances and spindle speed are the limiting factors in your work, and you have or will source a compatible air supply.
Pocket NC V2 Precision: TCPC, Repeatability, and Kinetic Control
Both models deliver ±0.0005 in XYZ homing repeatability, ±0.002 in axis repeatability, and an overall part tolerance of ±0.005 in. Tool Center Point Control maintains the tool contact point while the rotary axes move, standard on both configurations. Rotary compensation corrects for geometric errors in the A and B axes during complex cuts.
Kinetic Control ships with every V2. The embedded simulator at sim.pocketnc.com validates G-code before cutting. CAM software is sourced separately; Penta provides post-processors for major platforms. Power supply is universal: 90-264 VAC, 47-63 Hz, single phase.
What the Pocket NC CNC Machine Can Cut: Materials and Work Envelope
Tested materials: G5 titanium, 6061 aluminum, 303 stainless, acetal (delrin), machinable wax. Optimal for: aluminum, softer steels, brass, delrin, wax, wood. Composites, ceramics, and gemstones are not recommended as abrasive particles enter the bearings and accelerate wear.
Practical work envelope: approximately 3 inches cubed. V2-10 ER-11 collet accepts tooling from 1/8 inch to 1/4 inch shank and metric equivalents. Thread milling is supported on both models.
Pocket NC V2 Price: V2-10 vs V2-50 Cost and Extras
The V2-10 starts at $7,499. The V2-50 starts at $10,799. Both include the machine, vise and hardware, a Datron end mill, a 2-inch wax cube, cables, and a power cord. The 1-year machine warranty and 2 years of remote service are included in both configurations. CAM software, additional tooling, and for the V2-50, a compatible air compressor, are purchased separately.
Financing is available for US business customers with two or more years of credit history. Penta Machine accepts credit card, PayPal, and Google Pay. The V2-10 at $7,499 is unusually affordable for a desktop 5-axis CNC mill with this length of delivery history. The V2-50 at $10,799 is a more specific professional buy, with a shorter spindle warranty and ongoing air infrastructure requirements.
Should You Buy the Pocket NC V2?
The Pocket NC V2 makes sense for anyone running a regular metal prototype workflow and paying machine shop rates to do it. The five-axis capability reduces multi-setup jobs to single setups, the embedded simulator reduces wasted stock, and the machine is available when you need it rather than when the shop queue allows.
Penta Machine has been shipping these for a decade, through five hardware iterations before the Kickstarter and continuous refinement since. That track record substantially reduces the uncertainty that comes with a hardware purchase this specialized.
The V2-10 at $7,499 is the right starting point for most buyers: no air supply required, ER-11 tooling is inexpensive and available everywhere, and it handles the full aluminum-to-delrin material range without additional infrastructure. The V2-50 at $10,799 is for professionals who need the surface finish and spindle speed, and are equipped to manage the air requirement. Both ship in 6 weeks.

FAQ about the Pocket NC V2 Desktop 5-Axis CNC Machine
Is the Pocket NC V2 beginner friendly?
Not really. The V2 requires working knowledge of CAD software to design parts and CAM software to generate toolpaths. The embedded simulator helps, and Penta provides post-processors for major CAM platforms, but this is not a plug-and-play machine. Build CAD/CAM experience before expecting usable parts out of the gate.
Can the Pocket NC V2 really cut titanium?
Yes, with caveats. The V2 has been tested on G5 titanium, but titanium cuts slowly on a desktop machine and requires careful toolpath strategy. The V2-50's 50,000 RPM spindle handles harder materials more effectively than the V2-10. For most buyers, aluminum, delrin, and softer steels are the practical daily-use materials.
What is the difference between the Pocket NC V2-10 and V2-50?
The only hardware difference is the spindle. The V2-10 runs up to 10,000 RPM with an ER-11 collet, no air required. The V2-50 reaches 50,000 RPM via an NSK spindle and requires compressed air at 1 gallon per minute at 25 psi. Frame, travel, and repeatability are identical on both. The V2-50 carries a 3-month spindle warranty vs. 1 year for the rest of the machine.
What software do you need for the Pocket NC V2?
You need CAD software to model parts and CAM software to generate toolpaths. Fusion 360 is the most common starting point and supports 5-axis toolpaths. Penta provides post-processors for several CAM platforms. The machine runs standard G-code and includes an embedded simulator at sim.pocketnc.com for validating cuts before they run.
Where can I buy the Pocket NC V2?
The V2-10 and V2-50 are available directly from Penta Machine. Current lead time is 6 weeks. Financing is available for US business customers. Penta Machine accepts credit card, PayPal, and Google Pay.
