The JET JMD-45GH Geared Head Square Column Mill/Drill with Newall DP700 2-Axis DRO & X-Powerfeed is a heavy-duty mill/drill built for precision drilling and milling in a shop environment. This is a mill/drill designed for precision drilling, table positioning, and controlled metalworking operations. Model Number JMD-45GH, Stock Number JT9-351151. If you need a machine that gives you more rigidity and better position control than a lighter bench model, this is the step up.

What makes this machine matter is the combination of a geared head, a square column design, and a built-in measurement and feed package. The geared head gives you 6 spindle speeds with a 65 to 1550 RPM range, so you can match the cut to the material without a slow belt-change routine. The Newall DP700 2-axis digital readout helps you track table position accurately, while the X-axis powerfeed reduces hand cranking on longer passes and repetitive work.

The structure is built around a cast iron body and a square column with dovetail ways, which is the kind of design you want when rigidity matters. On a machine in this class, stiffness is not a luxury. It directly affects hole accuracy, surface finish, and how confidently you can work through tougher setups. The 9-1/2 x 32-1/4 inch table gives you usable work support, and the 20-1/2 inch longitudinal travel plus 8.25 inch cross travel give the table enough range for a wide variety of shop tasks.

The spindle setup is built for real work, not just light hobby use. You get an R8 spindle taper, which is a common and practical choice because tooling is easy to source and widely used in milling applications. The 3 inch quill diameter and 5 inch spindle travel support controlled feed and depth changes, and the machine is rated for up to a 4 inch face mill capacity. There is also a calibrated fine down feed built in, which is exactly the kind of detail that helps when the cut needs more feel and control.

JET also built in shop-use features that make the machine easier to live with day to day. The head tilts 90 degrees left and right for angled work, a spindle guard adds a layer of protection at the point of operation, and the work lamp helps visibility at the table. The quick-select gear shift levers are another practical win. When speed changes are easier, operators are more likely to run the right speed instead of just making do.

Power comes from a 1.5 horsepower motor with 115/230V input. At 728 lbs net weight, this is not a portable shop tool and it is not pretending to be. That weight is part of the value because mass helps damp vibration and supports more stable cutting. Overall dimensions are listed at 29 x 36 x 50 inches, with a base size of 26-11/16 x 15-15/16 inches, so this machine needs a proper place in the shop and a plan for installation.

This JET mill/drill makes the most sense for serious metalworking shops, maintenance departments, toolrooms, schools, and advanced users who want DRO-guided positioning and powerfeed support in one package. If your work involves precision drilling, slotting, facing, and general milling where rigidity and repeatability matter, the JET JMD-45GH Geared Head Square Column Mill/Drill with Newall DP700 2-Axis DRO & X-Powerfeed is built for that job. If you only need occasional light drilling, this is more machine than you need. If you want a production-minded square column mill/drill with the right control features already in place, it is right in its lane.
