12" Manual Mill
12" Manual Mill with optional accessory package
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
