8″ Tabletop Lathe with DRO
Our 8″ DRO Benchtop lathes 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 each axis. 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 lathe is ideal for customers who need a small-format machine capable of producing highly accurate, precision parts. Proudly made in the USA, all our lathes 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.

Thread-Cutting Attachment
A key advantage of owning a lathe is the ability to machine threads. While taps and dies can cut many threads, acquiring a comprehensive tap and die set to cover all non-standard thread sizes can be costly. Sherline provides a unique and versatile thread-cutting attachment for its lathe. This affordable attachment enables you to machine thirty-six different unified thread pitches (ranging from 80 to 5 threads per inch) and twenty-eight different metric thread pitches (ranging from .25 to 2.0 mm). It also allows for both left-hand and right-hand threading. A 60° carbide cutting tool is included, but you can also grind a standard high-speed steel tool to cut various thread forms at any pitch diameter. This versatility allows you to machine both standard and non-standard inside or outside threads, as long as they fall within the lathe’s size limitations.
Note: Ensure you lubricate the gears with light oil before using the threading attachment.
The attachment includes:
- 15 aluminum gears
- Mounting brackets
- Engagement mechanism
- 4.00" (102 mm) handwheel
Thread cutting on the Sherline lathe is accomplished by gearing the spindle to the leadscrew. As the spindle is rotated using the handwheel mounted on the headstock spindle, the tool advances according to the gear ratio. Once the tool reaches the end of its movement, simply stop cranking, reverse the tool, and turn the spindle in the opposite direction until the tool passes its starting point. Reset the tool, and you’re ready for the next pass. It’s as straightforward as tapping! By using the supplied 127-tooth gear, you can cut true metric threads on an inch lathe or true inch threads on a metric lathe.
⚠️ Note: The thread-cutting attachment is not compatible with the 3C Headstock.
Adapting the Leadscrew Engagement Lever for Use with Digital Readout (DRO)
If you plan to use the leadscrew engagement lever with the Thread Cutting Attachment in conjunction with a Digital Readout (DRO), you will need to equip your lathe with the DRO sliding shaft (sold separately) for proper leadscrew engagement.Gear Selection Calculator
The Sherline Thread Attachment Calculator, created by Joo Beng Koh of Singapore, automates gear selection based on your desired thread count. Originally shared on the Sherline Lathe & Mill Facebook Group, Joo Beng graciously allowed us to feature this tool on our website. The calculator simplifies the setup process, particularly for users who frequently change their thread specifications.
For instructions, select the desired parameters in the light yellow fields, and the corresponding gear selections will appear in the green boxes. An accompanying image shows the correct gear placement along with step-by-step guidance for installation. This tool has greatly improved the process for Joo Beng and can help others as well.
