Frequently Asked Questions

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

This mill is configured with an NST #40 spindle taper, which provides broad compatibility with a wide range of standard milling toolholders, collets, and end mill adapters commonly used in professional shop environments.

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

The JTM-1254VS offers a variable spindle speed range of 80 to 3,800 RPM, allowing operators to dial in the optimal cutting speed for a variety of materials and tooling diameters without the need for manual gear changes.

What DRO system is included, and does it cover all three axes?

This package includes the ACU-RITE 203 3X (K) DRO, which provides digital readout on all three axes - X, Y, and Z - giving operators precise position feedback during milling, boring, and drilling operations.

How does the three-stage power downfeed work, and does it have an automatic stop?

The three-stage power downfeed provides three selectable quill down feed rates - .0015, .003, and .008 IPR - and is equipped with an automatic stop feature, allowing operators to preset a depth and have the quill disengage automatically when that depth is reached for repeatable, accurate results.
