Frequently Asked Questions

What spindle taper does the JET JTM-1254RVS use?

This mill uses an R-8 spindle taper, which is one of the most common and widely supported tapers in manual vertical milling. It accepts collets with a capacity range of 1/8" to 1".

What is the spindle speed range on this variable speed mill?

The JTM-1254RVS offers a variable spindle speed range of 80 to 3,800 RPM, allowing operators to dial in the optimal cutting speed for a wide variety of materials and tooling sizes.

How does the pneumatic power drawbar work and what are its benefits?

The air-powered (pneumatic) drawbar allows for fast, convenient tooling changes directly at the spindle without the need for manual wrenching. This significantly reduces changeover time and operator fatigue during high-production operations.

What quill down feed rates are available, and does the machine have an automatic stop feature?

The quill offers three down feed rates of .0015, .003, and .008 inches per revolution (IPR). The machine also includes a three-stage power downfeed with an automatic stop, enabling precise and repeatable depth-of-cut control for drilling and boring operations.
