Frequently Asked Questions

What spindle taper does the JMD-40GHPF use, and what tooling does it accept?

The JMD-40GHPF is equipped with an R8 spindle, which allows use of all mill tooling. The R8 taper is one of the most widely available standards in the industry, giving operators broad compatibility with end mills, collets, drill chucks, boring heads, and other common mill accessories.

What is the spindle speed range on this machine?

The JMD-40GHPF delivers a spindle speed range of 65-1550 RPM across 6 speeds. Speed changes are made quickly and efficiently through quick-select gear shift levers, minimizing downtime between operations.

Does this mill/drill include power downfeed as a standard feature?

Yes. Power Downfeed is standard on the JMD-40GHPF, providing automated spindle advance for consistent and controlled material removal. The auto spindle travel extends to 4-1/2 inches, and a calibrated fine down feed is built in for precise depth management. An easy to read internal depth gauge further supports accurate depth monitoring.

Is the Mill Drill Stand included with the JMD-40GHPF?

No. The Mill Drill Stand, p/n 350045, shown in some images, is optional and not included with the machine. It must be purchased separately if a dedicated stand is desired for your installation.
