JET JTM-1050VS2 Mill with 3-Axis ACU-RITE 203 DRO (Quill) and X & Y-Axis Powerfeeds is a professional-grade variable speed knee mill engineered by JET for precision milling operations in demanding shop environments. Built on Certified Meehanite castings with a hardened and ground 10" x 50" table, this machine combines a wide spindle speed range, integrated digital readout, and dual-axis powerfeeds to deliver consistent, high-accuracy results across a broad range of milling applications. High precision Class 7 bearings support the spindle, and a three-stage power downfeed with automatic stop makes operation straightforward and repeatable. The JET JTM-1050VS2 is backed by the industry-leading JET Two Year Warranty.

Frequently Asked Questions

What spindle taper does the JET JTM-1050VS2 use?

The JTM-1050VS2 uses an R-8 spindle taper, which is a widely adopted standard in knee mill tooling and compatible with a broad range of collets, end mill holders, and accessories. The collet capacity range is 1/8 to 7/8 inch.

Does this mill include a coolant pump?

The JTM-1050VS2 features an internal coolant tank built into the base for use with a coolant system; however, the coolant pump is not included and must be purchased separately.

What does the one shot lubrication system do?

The one shot lubrication system allows the operator to lubricate all critical wear surfaces - including the ways, lead screws, and gibs - with a single action, ensuring consistent maintenance and reducing the time required for routine upkeep.

What is the full spindle speed range, and how is it controlled?

The JTM-1050VS2 offers a variable spindle speed range from 70 to 3,800 RPM, giving operators the flexibility to machine a wide variety of materials at optimal cutting speeds. The variable speed drive allows smooth speed adjustment without the need to change belt positions for every speed setting.
