Frequently Asked Questions

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

The JTM-1254VS uses an NST #40 spindle taper, which accepts a wide range of standard NT-40 tooling including end mill holders, collet chucks, and face mill adapters.

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

The spindle speed ranges from 80 to 3,800 RPM, providing the flexibility needed to machine a broad variety of materials including steel, aluminum, brass, and plastics at optimal cutting speeds.

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

The air power drawbar uses shop air pressure to engage and release the drawbar mechanism, allowing the operator to change tooling quickly without manual wrench tightening. This significantly reduces tool change time and operator fatigue during production runs.

What electrical power is required to operate the JTM-1254VS?

The JTM-1254VS is powered by a 5HP motor requiring 230/460V, 3-phase electrical service. Additionally, there are two 115V outlets on the electrical box dedicated specifically for the Powerfeeds.
