Frequently Asked Questions

What spindle taper does the JET JTM-1254RVS use, and what collet sizes are compatible?

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 selection of standard R-8 tooling available on the market.

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

The spindle speed ranges from 80 to 3,800 RPM, allowing the operator to dial in the correct cutting speed for a broad variety of materials, from soft aluminum to hardened steel.

What are the available quill down feed rates for the three-stage power downfeed?

The three-stage power downfeed offers feed rates of .0015, .003, and .008 inches per revolution (IPR), each with an automatic stop feature for repeatable depth control during drilling and boring operations.

How does the pneumatic power drawbar improve tool change efficiency?

The pneumatic (air-powered) drawbar automates the clamping and release of tooling in the R-8 spindle, dramatically reducing the time and effort required to change cutting tools compared to a manual drawbar, which supports higher productivity during multi-operation jobs.
