Metal Mill Drill Machine with R8 Taper for Precision Machining
JET JMD-18 Metal Working Mill/Drill with R-8 Taper 2 HP 115/230V 1PH
Product Overview
The JET JMD-18 Metal Working Mill/Drill is a versatile machine designed for shops that need both drilling and milling capabilities without the footprint of a full-size milling machine. Powered by a 2 HP single-phase motor and equipped with an R-8 spindle taper, the JMD-18 provides the tooling compatibility and machining capacity needed for a wide range of general-purpose metalworking applications.
Its 12-speed belt-driven head offers spindle speeds from 150 to 3,000 RPM, allowing operators to select an appropriate speed for different cutters, workpiece materials, and machining operations. A large cast-iron work table, 360° swiveling head, and rigid one-piece column further enhance the machine's versatility.
The JMD-18 is well suited for maintenance departments, fabrication shops, repair facilities, machine shops, and users who need a dependable mill/drill for drilling, facing, slotting, and light milling work.
Key Features
2 HP motor provides substantial power for drilling and milling.
115/230V single-phase operation provides flexible electrical installation options.
R-8 spindle taper accepts a broad selection of standard milling tooling.
12 spindle speeds range from 150 to 3,000 RPM for different cutting conditions.
1-1/4-inch drilling capacity handles demanding general-purpose drilling.
3-inch face-mill capacity accommodates larger milling cutters.
3/4-inch end-mill capacity supports common end-milling applications.
360° swiveling head provides flexibility for angled machining.
One-piece cast-iron column helps maintain rigidity and stability.
Heavy-duty tapered roller bearings support the spindle for smooth operation.
Large cast-iron table provides a solid work surface for parts and fixtures.
20-1/2-inch longitudinal table travel provides useful positioning range.
Internal depth gauge helps establish consistent drilling depths.
Quick-stop knob provides a convenient reference for repetitive drilling.
Forward/reverse spindle switch adds operating flexibility.
Work light improves visibility around the machining area.
R-8 Spindle Taper
The JMD-18 uses an R-8 spindle taper, a common standard on milling machines and mill/drills. This makes it compatible with a wide selection of R-8 collets, end-mill holders, arbors, and other milling accessories.
The R-8 system is particularly useful for general-purpose shops because compatible tooling is widely available in different sizes and configurations.
Spindle Specifications
Spindle taper: R-8
Number of speeds: 12
Speed range: 150–3,000 RPM
Spindle travel: 5 in.
Quill diameter: 3 in.
12-Speed Belt-Driven Head
The JMD-18 uses a belt-driven head with 12 selectable spindle speeds. The range from 150 to 3,000 RPM gives the operator flexibility when switching between large and small cutters or different workpiece materials.
Lower speeds can be selected for larger tooling and demanding cuts, while higher speeds are available for smaller cutters and appropriate materials.
A belt-driven design also provides a straightforward mechanical arrangement for a general-purpose mill/drill.
Drilling & Milling Capacity
The JMD-18 is designed to perform both drilling and milling operations, giving users more flexibility than a conventional drill press.
Drilling Capacity
The maximum drilling capacity is 1-1/4 inches. This provides useful capacity for a broad range of general-purpose metalworking and fabrication tasks.
Milling Capacity
The machine is rated for:
Face milling: Up to 3 in.
End milling: Up to 3/4 in.
These capacities make the machine suitable for common operations such as:
Facing
Slotting
Edge milling
Light pocketing
Surface preparation
General material removal
Actual cutting capacity depends on the workpiece material, cutter geometry, spindle speed, feed rate, and workholding setup.
Milling Table
A large cast-iron work table provides a stable surface for securing workpieces and fixtures. The table measures approximately 9-1/2 x 32-1/4 inches and provides 20-1/2 inches of longitudinal travel.
Four T-slots allow the use of milling vises, clamps, hold-downs, and other compatible workholding equipment.
The generous table size makes the JMD-18 useful for both drilling patterns and milling operations where the workpiece needs to be repositioned along the table.
360° Swiveling Head
The machine head can swivel 360°, giving the operator additional flexibility when a machining operation requires an orientation other than standard vertical drilling or milling.
Head adjustment can be useful for:
Angled holes
Beveled machining
Specialized milling operations
Working on irregular components
Improving access to specific workpiece features
The one-piece cast-iron column provides the structural support for the adjustable head.
Motor & Electrical Specifications
The JMD-18 is equipped with a 2 HP single-phase motor designed for 115/230V operation. This dual-voltage capability provides flexibility when integrating the machine into different shop electrical systems.
Motor power: 2 HP
Voltage: 115/230V
Phase: 1 phase
Motor type: Induction
Drive system: Belt drive
Spindle speed range: 150–3,000 RPM
The machine's final electrical connection should be configured according to the motor nameplate, manufacturer's instructions, and applicable local electrical requirements.
Heavy-Duty Construction
The JMD-18 is built around a one-piece cast-iron column designed to provide a rigid foundation for machining. The approximately 4-inch-diameter column supports the head and helps minimize unwanted movement.
Heavy-duty tapered roller bearings support the spindle, while the cast-iron table and base provide additional stability. Proper workholding and machine mounting are still essential for achieving the best machining results.
User-Friendly Features
JET incorporates several features intended to make routine machining more convenient:
Internal Depth Gauge
The built-in depth gauge provides a reference for controlling drilling depth and can be useful when producing multiple holes to similar dimensions.
Quick-Stop Knob
A quick-stop mechanism provides a convenient reference point for repetitive drilling operations.
Forward/Reverse Control
The spindle can be operated in forward or reverse, providing additional flexibility for compatible tooling and machining applications.
Work Light
The integrated work light improves visibility around the cutting area, making it easier to observe the cutter and workpiece during operation.
Typical Applications
The JET JMD-18 is suitable for a variety of metalworking tasks, including:
General drilling
Face milling
End milling
Slotting
Facing
Hole-pattern machining
Maintenance and repair
Fabrication
Prototype work
Equipment modification
Small-batch machining
