Frequently Asked Questions

What spindle taper does the JET JTM-1254RVS use, and what is the collet capacity range?

The JTM-1254RVS uses an R-8 spindle taper with a collet capacity ranging from 1/8" to 1", making it compatible with a wide variety of standard R-8 tooling used in professional milling applications.

What is the variable spindle speed range on this mill?

The spindle speed is variable from 80 to 3,800 RPM, allowing operators to dial in the optimal cutting speed for different materials and tool diameters without stopping to change belt positions.

What power downfeed rates are available, and does the mill have an automatic stop feature?

The JTM-1254RVS features a three-stage power downfeed with available feed rates of .0015, .003, and .008 inches per revolution (IPR). The power downfeed also includes an automatic stop for precise, repeatable depth control.

Are the two 115V outlets on the electrical box general-purpose outlets?

No. The two 115V outlets located on the electrical box are dedicated for Powerfeeds only and are not intended for general-purpose use with other accessories or equipment.
