12″ Deluxe Mill
The 12″ Deluxe Tabletop Mill is Sherline’s most popular milling machine, offering an ideal balance of precision, versatility, and value.
Like all Sherline milling machines, the 12″ mill is built in the USA and features:
- Precision-machined dovetailed slides with adjustable gibs
- Permanently lubricated spindle bearings
- Adjustable preload, anti-backlash leadscrews
- A high-torque 90V DC motor with electronic speed control
Spindle speed is continuously variable from 70 to 2800 RPM—no belt or gear changes required. A secondary pulley position provides additional torque for low-speed operations.
This compact tabletop mill is ideal for customers who need a high-precision mini milling machine for small parts. Despite its small footprint, it’s capable of machining wood, plastic, aluminum, and even steel with exceptional accuracy. The 10″ benchtop mill delivers full-size performance in a desktop-sized package—making it perfect for home shops, labs, and prototyping environments.
Note on Ordering a Metric Mill – Most Sherline cutting tool, such as center drills, are offered in fractional sizes. If you opt for a metric machine with metric collets or holders, you’ll need to order compatible fractional-size holders to use these tools effectively.
Standard Equipment for the 12″ Benchtop Mill
- 12″ base with laser-engraved scales
- Brass leadscrew cover that keeps chips off the rear of the Y-axis leadscrew
- 2.75″ (70 mm) x 13.0″ (330 mm) table with laser-engraved scales and two T-slots
- 1.235″ headstock spacer block
- Resettable, zero-adjustable handwheels:
- (2) 2″ (51 mm) handwheels on X- and Y-axes
- (1) 2-1/2″ (63 mm) handwheel on Z-axis
- All with laser-engraved aluminum collars
- ¼” Drill Chuck w/ key, #1 Morse arbor with drawbolt
- Pulleys, drive belt, three hexagonal keys, spindle bars, gib removal tool, eight-foot three-wire power cord, and instruction manual
- Oil reservoirs on the X/Y axes and the Z axis help keep critical parts lubricated. These were initially developed for CNC machines that run constantly for hours on end but can benefit manual machines as well
12″ Mill with DRO
Our 12" DRO Benchtop Mill includes a digital readout box and specialized handwheels with built-in electronic encoders that replace the standard handwheels (standard handwheels are not included with the DRO option). These DRO handwheels interface with the readout box, which translates handwheel movement into precise digital readings for all three axes. Each axis can be zeroed at any time with the push of a button, and the DRO continuously displays spindle RPM whenever the motor is running. The readout is compatible with both inch and metric machines.
This compact DRO mill is ideal for customers who need a small-format machine capable of producing highly accurate, precision parts. Proudly made in the USA, all our mills are backed by exceptional customer support. Despite its desktop size, this machine delivers full-size performance—capable of cutting wood, plastic, aluminum, and even steel with excellent rigidity and accuracy.
Using the DRO System
The DRO displays each axis position relative to a zero point you set.
- Inch models show position to 0.0005″ (three and a half decimal places)
- Metric models show position to 0.01 mm
The system supports both ball screw and leadscrew machines. As well as the ability to use Metric DROs on inch machines or inch DROs on metric machines. It features six selectable modes based on machine type (mill or lathe), screw type (leadscrew or ball screw), and preferred display units (inch or metric). For setup instructions, refer to the official DRO Mode Instructions.
You can electronically compensate for backlash by inputting the measured backlash value for each axis. When the direction of handwheel rotation reverses, the DRO subtracts the backlash before updating the position—eliminating common errors and making it easier to track travel distance and direction. The power supply automatically switches between 120V and 240V, making it suitable for use in countries with 220–240V electrical current. A socket adapter may be required outside North America.
Notes on Ordering a Metric Mill – Most of our cutting tools, such as center drills, are manufactured in fractional sizes. If you’re using a metric machine with metric collets or end mill holders, you’ll need to order fractional holders to fit these tools.Standard Equipment for the 12″ Benchtop Mill

12″ CNC-Ready Mill
Our CNC-ready tabletop mill is ideal for customers seeking a compact CNC milling solution for producing small, precision parts. Made in the USA and backed by exceptional customer service, this mill offers full-size machine accuracy in a desktop footprint. Despite its size, it’s capable of cutting wood, plastic, aluminum, and even steel with impressive rigidity and precision.
CNC-ready mills come with factory-installed stepper motor mounts in place of handwheels and are ready for you to add your own stepper motors and CNC controls. Please note: these are not turn-key systems and cannot be operated until motors and controls are installed. CNC-ready machines do not include stepper motors, a computer, or CNC software.
Sherline recommends dual-shaft stepper motors so manual control is still possible using the included handwheels, which mount to the rear shaft once the motors are installed. Sherline also offers high-quality stepper motors and CNC components to complete your system.
Additionally, you can explore various aftermarket suppliers for compatible motors, drivers, and software. Visit our CNC Dealers page for a list of suppliers and links to their websites.

14″ 8-direction Mill
The Deluxe 8-Direction Milling Machine is one of the most versatile mills Sherline offers. In addition to standard X-, Y-, and Z-axis movement, this model provides five additional directions of headstock adjustment—allowing you to position the spindle for drilling or milling operations from nearly any angle.
- The headstock pivots up to 90° left or right.
- The column bed also rotates side to side up to 90°, enabling angled drilling.
- A specialized knuckle joint allows the column to tilt front to back.
- The ram-style column base can swing side to side up to 90°, offering even greater flexibility.
- Loosening the column cap lets the ram move in and out, providing over 5.5″ of additional travel.
With this wide range of movement, the machining possibilities are nearly limitless within the compact work envelope of the machine. The 14″ base also increases Y-axis travel by 2″ compared to the Model 5400 mill, making it a powerful tool for advanced miniature machining applications.
The 8-direction benchtop mill is ideal for users who need a small, precision milling machine capable of high-accuracy work. Like all Sherline mills, it is made in the USA and supported by unmatched customer service. Despite its compact size, this 14″ benchtop mill is engineered to handle wood, plastic, aluminum, and even steel—delivering full-size machine precision in a desktop footprint.

18″ NexGen Mill
The Sherline NexGen Benchtop Mill is the largest vertical milling machine we offer. As Sherline mills have become increasingly popular in industrial, laboratory, and educational settings, the need for a larger-capacity mill led to the development of the NexGen model. This benchtop mill features an expanded mill base, a longer crosslide table, and an extended column—providing greater work area and capability than our Deluxe 8-Direction Benchtop Mill (Series 2000/2100).
To fully support the extended travel of the column, we’ve increased the cross-section of the column base for added rigidity. To further improve stability during heavy cuts, the column arm no longer swings side to side. However, you still retain full flexibility with 90° rotation to the left and right, as well as in-and-out column movement—giving the NexGen mill a total of seven directions of adjustment, including X, Y, Z, and headstock rotation.
The NexGen mill is ideal for customers seeking a compact, high-precision mini mill for small parts. All Sherline milling machines are made in the USA and backed by exceptional customer support. Despite its small footprint, this 18" benchtop mill delivers full-size machining accuracy. It’s capable of cutting wood, plastic, aluminum, and even steel with precision and rigidity.
