JET JTM-1050EVS2 10" × 50" Electronic Variable Speed Vertical Milling Machine
Are you losing time between cuts resetting speeds by hand and fighting a table that drifts under load?
What if your mill held position through every pass and let you dial in the right spindle speed without stopping the work?
Meet the JET JTM-1050EVS2 10" × 50" Electronic Variable Speed Vertical Milling Machine, a full-size knee mill built for shops that demand consistent results on steel, aluminum, and cast iron day after day.
With the JTM-1050EVS2, you get a Meehanite-cast column and base, Class 7 spindle bearings, Turcite-B way coating, and a variable speed range of 60 to 4,500 RPM that covers facing, boring, and end milling without a belt change.
When this machine is on your floor, you spend less time setting up and more time cutting to spec.
JET JTM-1050EVS2 for Accurate, Repeatable Milling on Metal
Meehanite-Cast Column and Base Resist Flex Under Load
The column and base are cast using the certified Meehanite process, which produces a dense, consistent iron structure. That rigidity keeps the spindle in alignment when you are taking heavy cuts in steel or cast iron. The base also incorporates a leveling design that lets you set the machine flat without raising it off the floor.
Class 7 Spindle Bearings Maintain Accuracy in Heavy Cuts
Class 7 spindle bearings are rated for high-load, high-speed operation. They support the spindle against radial and axial forces so your cuts stay true under pressure. The spindle head is internally cooled, which pulls heat away from the bearings and motor during extended runs and extends their service life.
Electronic Variable Speed Drive Covers 60 to 4,500 RPM
The Delta inverter-driven variable speed system lets you set spindle speed with a dial rather than swapping belts. The 60 to 4,500 RPM range handles everything from slow-speed facing on large-diameter cutters to high-speed finishing on aluminum. Speed changes happen without stopping or reaching inside the head.
Turcite-B Way Coating and Dual Axis Locks Keep Table Position
The X and Y-axis ways are coated with Turcite-B, a low-friction bearing material that reduces vibration and keeps table movement smooth and consistent. Dual locks on every moveable surface let you fix position on any axis before a cut. The table and ways are hardened to 54 HRC and precision ground, so contact surfaces stay accurate under daily use.
