PwnCNC Spindle Kit

Upgrade your CNC with a powerful, configurable spindle kit built around your machine, voltage, and cooling preferences.

The PwnCNC Spindle Kit is our budget-friendly spindle upgrade package for customers who want the core components needed to add a VFD-controlled spindle to their CNC. Each kit is configured based on your selections and includes a spindle motor, pre-programmed VFD, spindle cable, collets, wrenches, and cooling components when applicable.

This kit is a great option for customers who are comfortable completing the final installation, mounting, enclosure planning, and machine-specific control wiring themselves.

Spindle Kit vs. Spindle System

This product is a configurable spindle kit. It includes the major spindle components, but it does not include a fully enclosed, plug-and-play VFD enclosure.

If you want a cleaner, more complete installation experience, consider our PwnCNC Spindle System instead. The Spindle System includes the spindle kit components preassembled into an integrated VFD enclosure for a more finished installation.

Configured for Your Setup

Choose your spindle motor, voltage, cooling style, and compatible options from the dropdowns above. Based on your selections, the appropriate components will be added to your cart as part of the kit.

Important: This is a configurable bundle. If you manually remove individual bundle components from your cart, those removed items will not ship, even if they were part of your original selections.

Spindle Motor Options

• 1.5kW, 110V, 65mm, ER11 — air-cooled or water-cooled
• 1.5kW, 110V, 80mm, ER20 — air-cooled or water-cooled
• 2.2kW, 220V, 80mm, ER20 — air-cooled or water-cooled

Special-order spindle motors may be available upon request. Special orders typically require additional lead time.

What’s Included

• PwnCNC 110V or 220V VFD, pre-programmed for supported spindle control methods
• Detachable VFD keypad with manual speed control dial
• Power cord matched to selected voltage
• Selected spindle motor
• 20' pre-crimped shielded spindle cable
• Three collets matched to spindle size
• Two spindle wrenches matched to spindle size
• Cooling pump and tubing for water-cooled models

Collets and Wrenches

ER11 spindle kits include:

• 1/16" ER11 collet
• 1/8" ER11 collet
• 1/4" ER11 collet
• 13mm and 17mm wrenches

ER20 spindle kits include:

• 1/8" ER20 collet
• 1/4" ER20 collet
• 1/2" ER20 collet
• 21mm and 30mm wrenches

Water-Cooled Models

Water-cooled spindle kits include a cooling pump and tubing. A coolant reservoir and coolant liquid are not included. Many customers use a dedicated bucket or reservoir with an appropriate coolant mixture.

The included tubing is 10mm OD and may require minor adjustment or “massaging” to fit through the standard compression nuts on some water-cooled spindle motors. For a cleaner fit, consider adding our Kool Connectors.

What’s Not Included

• CNC controller control cable
• VFD enclosure
• Keypad mount or keypad extension cable
• Coolant liquid
• Coolant reservoir
• Spindle mount, unless selected or included separately
• Machine-specific mounting hardware not listed above

The included VFD should be installed safely and properly. We recommend enclosing the VFD in an appropriate enclosure as part of your installation.

Technical Highlights

• Operating range: 8,000–24,000 RPM
• ER11 collets on 65mm motors
• ER20 collets on 80mm motors
• 1.5kW motors draw approximately 12A at 110V
• 2.2kW motors draw approximately 10A at 220V
• Supports G-code speed control using compatible PWM or Modbus setups
• Quiet fan mode configured on supported VFDs

Build Time and Availability

PwnCNC Spindle Kits are assembled, configured, and tested in-house before shipment. While we keep many components in stock, each kit is built based on your selected motor, voltage, cooling style, and controller-related options.

Most spindle kits ship within 1–2 weeks. Depending on motor availability, special-order components, or current order volume, lead time may extend to 4–6 weeks.

If your build timeline is critical, please contact us before ordering so we can confirm current availability.

Compatibility

PwnCNC Spindle Kits are compatible with many popular CNC machines, including Onefinity, Shapeoko, and other CNC platforms when configured correctly. Some machines require controller-specific cables, mounts, brackets, or setup steps.

Please review our compatibility documentation and machine-specific installation guides before ordering.

Important Notes

• This is not the same product as our enclosed PwnCNC Spindle System.
• This kit requires proper installation, grounding, mounting, and machine-specific setup.
• The spindle cable shield must be properly drained to ground on the VFD side.
• Controller cables are sold separately unless specifically selected or included.
• Water-cooled models require coolant liquid and a reservoir, sold separately.
• VFD enclosure is not included and is recommended for safe installation.
• Always follow proper electrical safety practices when installing spindle equipment.

Recommended Add-Ons

• Spindle control cable for your CNC controller
• VFD enclosure or upgrade to a complete Spindle System
• Keypad mount and keypad extension cable
• Kool Connectors for water-cooled spindle setups
• Additional ER11 or ER20 collets
• Cyclone Bits
