- NEMA 23 frame size – fits Sherline CNC-ready mills, lathes, and rotary tables.
- Dual-shaft design – both ends of the shaft are usable; flats are ground on each end for secure attachment of handwheels and couplings.
- Standard step angle – 1.8° per step (200 steps/rev) for precise motion control.
- 2.0 A/phase – both motors are rated at 2.0 amps and work with existing Sherline CNC power supplies and driver electronics.
- 6-lead wiring – allows use in a variety of bipolar or unipolar configurations (see spec sheets for wiring diagrams).
- Designed for Sherline CNC – plug-and-play with Sherline driver boxes and motion controllers when used with the supplied connectors.
- Coupler requirement: Because of the increased torque, the high-torque motor (P/N 67126) must be used with the updated CNC coupling (P/N 671052). This coupling replaces the older 3-slot coupling (P/N 67105).
- Motor mounts: When used with a Sherline stepper motor mount (P/N 67101), be sure that the shaft entering the coupling has a flat aligned with the set screw. Tightening against the round shaft can damage the shaft and make removal difficult.
- Handwheel use: The dual-shaft design lets you mount a handwheel on the rear shaft for manual operation when the drivers are powered down. When the motors are energized, they hold position and cannot be moved easily by hand.
- Controller compatibility: P/N 67127 with the 5-pin DIN plug is designed to plug directly into Sherline’s 4-axis driver box, CNC systems, and linear and rotary controllers. P/N 67130 (no plug) is intended for non-Sherline or custom controllers.

Headstock Riser Block Set
The standard Sherline lathe can accommodate parts up to 3.5" (90 mm) in diameter. However, there are times when you may need to work on larger pieces. The Sherline headstock spacer block increases the lathe’s maximum working diameter to 6" (152 mm), significantly expanding its capabilities.
This set includes a 1.235" (31.37 mm) spacer block that fits beneath the headstock, along with a riser-rocker tool post to elevate the cutting tool accordingly. If you plan to turn parts between centers while using the headstock riser, you’ll also need a tailstock riser block to maintain proper alignment.
Note: Although the spacer block allows turning parts up to 6" in diameter, the lathe’s motor power remains unchanged. This accessory is best suited for machining easy-to-cut materials or for occasional use when extra clearance is needed. If your work frequently requires this added capacity, upgrading to a larger lathe may be advisable.

Horological Milling Machine Bushing and Depthing Accessory
This accessory was developed based on a concept shared by longtime Sherline user and Craftsman of the Year, Jerry Kieffer. The idea is to adapt a small milling machine for multiple clock and watch repair tasks - replacing the need for several specialized tools. It simplifies and enhances depthing by letting you position a gear exactly where it needs to be, check its mesh with a mating gear, and then precisely machine the bushing hole in the correct location.
With the Sherline mill, you can precisely position and align clock and watch components, allowing for highly accurate machining of bushing holes in both size and location. Once the machining is complete, the mill can also serve as a manual press for bushing insertion.
Used in combination with your Sherline mill, this accessory transforms your setup into a versatile three-in-one clock and watch repair machine - while retaining the full functionality of a precision milling machine.
The photos show the depthing attachment on a 5400 mill. If you want to use it on a 5000-series mill you will need to add the headstock spacer block.
Stepper Motors
P/N 67127 – Standard Stepper Motor (with Plug)
The standard Sherline stepper motor (P/N 67127) comes pre-wired with six leads into a 5-pin DIN connector that plugs directly into Sherline’s CNC driver boxes and linear or rotary controllers. Simply plug each motor into the corresponding axis cable for a quick, clean setup. This motor is ideal for typical Sherline CNC applications where cutting loads are moderate, such as machining aluminum, brass, plastics, and light cuts in steel.P/N 67130 – Stepper Motor (Without Plug)
P/N 67130 is the same basic motor as P/N 67127 but supplied with six raw wire leads and no connector. It is intended for non-Sherline controllers or custom installations where a different pinout or connector is required.P/N 67126 – High-Torque Stepper Motor
Sherline’s high-torque stepper motor (P/N 67126) uses the same NEMA 23 frame size and 1/4" dual shaft as the standard motor, but delivers over 75% more holding torque. This added torque is especially useful on the Z-axis, where it can better handle the weight of the headstock and motor, and for heavier cuts or higher feed rates. Rated at 2 amps, the high-torque motor is fully compatible with all Sherline CNC machines, including complete CNC systems, the 4-axis driver box, CNC rotary tables, and Sherline linear and rotary controllers. No power supply upgrade is required. [/pane] [pane title="Specifications Comparison"]| Specification | P/N 67127 – Standard | P/N 67126 – High-Torque |
