Variable-Speed Geared Head
The JMD-45VSPFT uses a variable-speed geared head with a spindle range of 50–2,500 RPM. This gives the operator flexibility to select an appropriate speed for the material, cutter diameter, and machining operation.
The geared-head design is intended to deliver power to the cutting tool while maintaining the rigidity required for demanding drilling and milling work. JET also incorporates quick-select gear-shift controls for rapid spindle-speed changes.
Newall DP700 2-Axis Digital Readout
The Newall DP700 2-axis DRO provides a digital reference for machine positioning. It can make it easier to monitor table movement and establish repeatable machining positions without relying solely on graduated handwheels.
The DRO is particularly useful when:
- Locating multiple holes
- Establishing machining coordinates
- Repeating dimensions
- Monitoring table movement
- Setting up workpieces
- Performing repetitive machining operations
It complements the machine's mechanical positioning system rather than replacing proper measurement, workholding, and setup procedures.
X-Axis Table Powerfeed
The X-axis powerfeed automatically moves the table along its longitudinal axis. Instead of manually turning the table handwheel throughout a milling pass, the operator can use powered table movement to maintain a more consistent feed.
This can be especially useful for:
- Long milling passes
- Repetitive machining
- Surface milling
- Slotting operations
- Consistent feed-rate requirements
- Reducing operator fatigue
The table provides 20-1/2 inches of longitudinal travel, giving the powerfeed a substantial working range.
Power Downfeed
Unlike a basic mill/drill, the JMD-45VSPFT includes a power downfeed system with up to 4-1/4 inches of automatic spindle travel. The machine also provides a 5-inch total spindle travel and calibrated fine downfeed control.
This feature can be useful for repetitive drilling and machining operations where controlled spindle movement is desirable. The machine is also described by JET as having tapping capability in this configuration.
Milling and Drilling Capacity
The JMD-45VSPFT offers substantial capacity for a mill/drill of this class:
- 1-1/2-inch drilling capacity
- 4-inch face-mill capacity
- 3/4-inch end-mill capacity
The R-8 spindle taper accommodates commonly available milling tooling and accessories, making the machine adaptable to a variety of general machining operations.
Rigid Square Column Design
The machine uses a 7-7/8 x 7-5/8-inch square column with dovetail ways. This design provides a rigid support structure for the head and helps maintain stability during drilling and milling.
The head can tilt 90° to the left or right, providing additional flexibility for angled machining setups. The 19-11/16-inch swing and 18-1/8-inch maximum spindle-to-table distance also provide useful working clearance.
Large Worktable
The JMD-45VSPFT has a 9-1/2 x 32-1/4-inch table with 20-1/2 inches of longitudinal travel and approximately 8-1/4 inches of cross travel.
The table includes four 5/8-inch T-slots, allowing compatible vises, clamps, and workholding fixtures to be secured to the machine.
Practical Workshop Features
JET equips the machine with several features intended to improve day-to-day operation:
- Spindle guard
- Work lamp
- Internal depth gauge
- Calibrated fine downfeed
- Forward/reverse switch
- Quick-select spindle controls
- 90° left/right head tilt
- X-axis powerfeed
- Power downfeed
- Newall DP700 2-axis DRO
- R-8 spindle
The mill/drill is also specified as CSA/CUS certified.
Electrical and Installation Information
The machine uses a 1-1/2 HP, 115/230V, single-phase motor. Its overall dimensions are approximately 29 x 36 x 50 inches, and the listed net weight is 833 lb.
The optional mill/drill stand shown in some product imagery is not included as standard, so the installation arrangement should be confirmed before purchase.

- Professional machine shops
- Metal fabrication
- Industrial maintenance
- Equipment repair
- Toolmaking
- Prototyping
- Small-batch production
