Specifications may vary by exact JET stock number or production configuration. Confirm the specific model and current manufacturer documentation before purchase.
6-Speed Geared Head
The machine's 6-speed geared head provides direct mechanical power transmission to the spindle. The approximately 65–1,550 RPM range allows the operator to select an appropriate speed for different cutters, workpiece materials, and machining operations.
Lower spindle speeds are useful for larger tooling and heavier cuts, while higher speeds can be selected for smaller cutters and appropriate finishing work.
The mechanical gear drive is particularly beneficial when consistent spindle torque is required.
Power Downfeed
The integrated power downfeed provides automatic spindle movement during drilling and boring operations.
Instead of manually feeding the quill throughout the entire cut, the operator can use the power-feed mechanism to maintain controlled spindle movement.
This is useful for:
- Repetitive drilling
- Boring
- Counterboring
- Controlled-depth machining
- Production work
- Consistent hole-making
The machine also provides fine manual quill adjustment for applications requiring precise spindle positioning.
X-Axis Powerfeed
The X-axis powerfeed automates longitudinal movement of the worktable. With approximately 20-1/2 inches of X-axis travel, it can reduce operator effort during longer milling passes.
X-axis powerfeed is particularly useful for:
- Face milling
- Surface machining
- Long edge cuts
- Repetitive milling passes
- Consistent material removal
The appropriate feed rate should be selected according to the cutter, material, spindle speed, and depth of cut.
Newall DP500 2-Axis DRO
The Newall DP500 2-axis digital readout provides digital position information for the machine's primary table axes.
It can simplify:
- Hole-location work
- Repeated dimensions
- Slot positioning
- Pocket machining
- Workpiece setup
- X/Y coordinate positioning
- Returning to established table positions
The combination of the DRO and X-axis powerfeed gives the operator both digital positioning feedback and powered table movement, making repetitive machining more convenient.
Square-Column Construction
The rigid square column with dovetail ways provides structural support for the head and spindle assembly.
This design helps maintain stability when the machine encounters higher cutting forces and is suitable for operations such as:
- End milling
- Face milling
- Slotting
- Boring
- Drilling
- Counterboring
- General stock removal
Proper workholding remains essential when performing heavy cuts.
R8 Spindle
The machine uses an R8 spindle taper, a common milling-machine tooling standard.
Compatible accessories can include:
- R8 collets
- End mills
- Drill chucks
- Boring tools
- Face mills
- Other R8-compatible tooling
The published machine capacities include a 1-1/2-inch drilling capacity, 4-inch face-mill capacity, and 3/4-inch end-mill capacity.
Actual cutting performance depends on workpiece material, tooling, spindle speed, feed rate, depth of cut, and setup rigidity.
Tilting Head
The head tilts 90° to the left and 90° to the right, allowing the spindle to be positioned for angular machining.
This capability can be useful for:
- Angled holes
- Beveled surfaces
- Angular milling
- Specialized fixtures
- Non-standard machining setups
The head must be securely locked in position before machining.
Worktable
The 9-1/2 x 32-1/4-inch worktable provides a substantial surface for workpieces, vises, clamps, and fixtures.
Published travel specifications include:
- 20-1/2 inches longitudinal travel
- 8-1/4 inches cross travel
The table's 5/8-inch T-slots provide mounting points for compatible workholding accessories.
Motor and Electrical Configuration
A 1.5 HP single-phase motor powers the machine. The 115/230V configuration provides flexibility for workshops with suitable electrical service.
The machine should be configured for the correct voltage before operation. Electrical installation should follow JET's instructions and applicable local electrical requirements.

Maintenance
Regular maintenance helps preserve accuracy and extend machine service life.
Inspect:
- Spindle and bearings
- Gear head
- Quill and power-downfeed mechanism
- X-axis powerfeed
- Column and dovetail ways
- Table and T-slots
- Lead screws
- DRO scales and cables
- Electrical connections
- Lubrication points
Clean chips from the table and ways after machining. Keep the DRO scales protected from metal chips, coolant, and other contaminants.
Follow the manufacturer's recommended lubrication and maintenance schedule.
Safety Considerations
Always wear appropriate eye protection and use additional PPE required for the material and operation.
Secure the workpiece firmly using a suitable vise, clamp, or fixture. Never hold material by hand during milling or drilling.
Keep hands, clothing, jewelry, and hair away from rotating tooling and moving table components.
Do not measure, adjust, reposition a workpiece, or remove chips while the spindle is operating.
Disconnect the machine from the electrical supply before changing tooling or performing maintenance that requires access to electrical or moving components.
