1-1/4-Inch Drilling Capacity
The GHD-20T is designed for drilling holes up to 1-1/4 inches in diameter, depending on the material, tooling, and recommended operating conditions.
This capacity makes the machine suitable for applications involving:
- Steel
- Stainless steel
- Aluminum
- Cast iron
- Structural components
- General fabrication materials
Proper drill selection, cutting speed, feed rate, and coolant use are important when drilling larger holes.
Manual Feed Operation
The manual-feed spindle gives the operator direct control over the cutting tool.
This is particularly useful for job-shop work where drilling requirements can change frequently between workpieces. The operator can control spindle engagement and feed pressure according to the material and tooling being used.
Manual operation also provides useful tactile feedback during drilling, which can help when performing setup work, maintenance, and one-off machining tasks.
Tapping Capability
The GHD-20T incorporates tapping functionality, allowing the machine to perform internal-threading operations in addition to drilling.
This makes it possible to drill and tap workpieces without moving them to a separate machine, helping reduce setup time and maintain better positional consistency between the drilled hole and finished thread.
Tapping should be performed using appropriate tooling, spindle settings, lubrication, and machine procedures for the specific thread size and material.
2 HP Three-Phase Motor
A 2 HP three-phase motor provides the drive power required for the machine's heavy-duty drilling and tapping applications.
Three-phase power is commonly used in professional workshops and industrial facilities because it provides efficient motor operation and is well suited to machinery used for repeated machining work.
The machine is configured for 230V three-phase service.
12 Spindle Speeds
The GHD-20T features 12 spindle-speed settings, giving the operator a broad range of choices for matching spindle speed to the workpiece and cutting tool.
Different materials and drill diameters require different cutting speeds. The multiple-speed configuration allows users to select a more appropriate operating condition rather than relying on a single fixed speed.
For best results, spindle speed should be selected according to the tooling manufacturer's recommendations and the material being machined.
Geared-Head Design
The geared-head transmission provides direct mechanical power transfer from the motor to the spindle.
Compared with lighter belt-driven drill presses, a geared-head design is particularly suited to demanding metalworking because it provides a robust drive system for drilling larger holes and performing tapping operations.
The geared head also makes spindle-speed selection straightforward through the machine's dedicated speed settings.
Heavy-Duty Construction
The GHD-20T is built as a floor-standing industrial drill press, providing a stable platform for heavier workpieces.
A rigid machine structure helps minimize unwanted movement and vibration during drilling. The workpiece should still be securely clamped and adequately supported to achieve accurate results.
Typical Applications
The JET GHD-20T is suitable for:
- Machine shops
- Metal fabrication
- Industrial maintenance
- Welding and fabrication
- Equipment repair
- Manufacturing
- General machining
- Job-shop operations
- Production support
- Drilling and tapping work
Common Uses
Large-Hole Drilling
Produce larger holes in metal components using appropriate drill bits and cutting conditions.
Thread Tapping
Create internal threads after drilling the appropriate pilot hole.
Fabrication Work
Prepare holes and threaded mounting points in fabricated assemblies.
Maintenance and Repair
Drill and tap replacement parts or repair components without requiring multiple machines.
General Machining
Handle a wide variety of routine drilling operations in a professional workshop.
Benefits for Professional Users
1-1/4-Inch Drilling Capacity
Provides substantial drilling capability for general industrial metalworking.
Integrated Tapping Function
Allows drilling and tapping operations to be completed on the same machine.
12-Speed Configuration
Provides flexibility for different materials, drill diameters, and machining requirements.
2 HP Three-Phase Motor
Supplies the power needed for demanding drilling and tapping applications.
Geared-Head Transmission
Provides a robust mechanical drive system designed for professional metalworking.
Manual Feed Control
Gives the operator direct control over spindle movement and cutting pressure.
Maintenance
Regular maintenance helps keep the GHD-20T operating accurately and reliably.
- Inspect tooling before use.
- Keep drill bits and taps sharp and properly installed.
- Check spindle operation and tooling retention.
- Inspect the geared-head transmission for abnormal noise or vibration.
- Lubricate components according to JET's maintenance recommendations.
- Keep the work table and machine surfaces free of chips.
- Inspect belts, electrical components, and switches as applicable.
- Keep the machine clean and properly lubricated.
- Check the machine's mounting and structural components periodically.
- Disconnect electrical power before performing service or maintenance.
Safety Considerations
Always wear appropriate eye protection, hearing protection, safety footwear, and task-specific PPE when operating the drill press.
Secure the workpiece using an appropriate vise, clamp, or fixture. Never attempt to hold a workpiece by hand while drilling.
Keep hands, loose clothing, jewelry, and hair away from the rotating spindle and tooling.
Remove the chuck key or other setup tools before starting the machine. Never attempt to change tooling while the spindle is rotating.
Use the correct spindle speed, drill, tap, cutting fluid, and feed rate for the material being machined.
Because this model uses 230V three-phase electrical power, electrical installation and servicing should be performed by appropriately qualified personnel in accordance with applicable electrical requirements.
Disconnect and isolate the machine from its electrical supply before performing maintenance, changing tooling, or making adjustments that require access to moving components.
Why Choose the JET GHD-20T?
The JET GHD-20T Manual Feed Drill Press with Tapping combines a 1-1/4-inch drilling capacity, 2 HP three-phase motor, 230V operation, 12 spindle speeds, geared-head transmission, and tapping capability in a heavy-duty floor-standing machine.
Its ability to perform both drilling and tapping makes it especially useful for professional shops that need a versatile machine for fabrication, maintenance, repair, and general metalworking. The combination of manual feed and multiple spindle speeds also gives operators the control needed to handle a broad range of machining tasks.
