17″ Benchtop Lathe with DRO
Our 17″ 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.

- WW Collet Adapter*
- Drawbar & 3/8" Knockout Bar
- Set of 5 Collets: Inch set: 1/16", 1/8", 3/16", 1/4", and 5/16" Metric set: 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm, and 6.0 mm
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.
Tailstock Riser Block
For those customers interested in turning larger diameters between centers, the Tailstock Riser Block will raise the tailstock to correspond with the riser block kit, allowing you an additional 1.235" (31.37 mm) of clearance. The Tailstock Riser Block has a two-part dovetailed base to allow for easy installation and secure locking to the bed.
WW Collet Sets
Collets provide a quick, easy method of mounting cylindrical parts or bar stock in the lathe with a great deal of centering accuracy. Each collet is actually a small, precision 3-jaw chuck that fits into a special tapered adapter in the headstock. A drawbar that passes through the headstock and threads into the backside of the collet is used to draw the collet up into the tapered adapter. The adapter causes the jaws of the collet to close down, gripping the part to be machined. Typically, collets provide a very accurate part mounting system, but each size collet can accommodate only a small range of diameters of approximately ±.001" (.02mm).
WW collets differ from milling collets in that they have a hole all the way through the collet and drawbar. The maximum diameter stock that can pass entirely through the collet is 3/16" or 4.5mm. The WW collets that are larger than this diameter are sometimes referred to as "pot" chucks.The Sherline WW collet set includes a WW style collet taper adapter, a drawbar, and a set of five WW collets. These collets are manufactured by Sherline and are built to standard WW specifications; however, we have come across collets that are called WW and will not fit our drawbar and adapter. Be sure to check WW collets made by other manufacturers to be sure they fit our adapter before you purchase them. Sherline manufactures a slightly larger .315" adapter and drawbar set that will accommodate some of these other brands.
Collet AccuracyThese collets have a maximum runout of .002" or less. If the WW collet adapter is trued in as suggested in the instructions, it will run dead true. This will allow the collet runout to be at its best. Collet sizes above 3/16" (4.5mm), considered pot chucks, are not bored through. They are only bored .260" deep and depending on your setup and length of the part, you may experience greater runout further away from the front of the collet.
5-piece collet set includes:Other Collet Sets
Sherline also offers sets that include a wider selection of collets. It includes 17-inch size collets from 1/16 to 5/16", while the metric set includes 14 metric collets from 1.5 mm to 8.0 mm. These sets come in an oak box with a divider that has extra holes for more collets should you add them later. It also includes a drawbar, a collet adapter, knockout bar, two collet pot chucks, and a collet blank.
The largest set we offer includes 78 collets from 0.3 mm to 8.0 mm by 0.1 mm increments. This comes in an oak box with 96 holes in case you add some inch sizes but does not include the adapter, drawbar or other accessory items in the sets described above.
